Abstract

Enzymes can precisely control the speed and selectivity of chemical reactions by modifying locally the solvent–reactant interactions. To extrapolate these attributes to heterogeneous catalysts, we have employed thermoresponsive poly n-isopropylacrylamide (p-NIPAM) brushes bonded to silica spheres containing palladium. These polymers can form hydrogen bonds with water molecules at low temperatures (<32 °C) allowing the polymer to stay swollen. Detailed reaction kinetics of nitrite hydrogenation showed that p-NIPAM decreases the apparent activation barrier by a factor of 3 at low temperatures. Diffusion-ordered spectroscopy nuclear magnetic resonance and ab initio molecular dynamics simulations showed that when p-NIPAM is present, water molecules near the surface are less mobile. This confinement perturbs the water interaction with the metal, reducing the barrier for the proton–electron transfer reduction of nitrite. Notably, this enhancement vanishes at high temperature as the polymer collapses on itself exposing the Pd to unconfined water. The fully reversible nature of this process opens the door for creating homeostatic catalysts with controlled water-confinement.

Abstract

Achieving the United Nations sustainable development goals requires industry and society to develop tools and processes that work at all scales, enabling goods delivery, services, and technology to large conglomerates and remote regions. Process Intensification (PI) is a technological advance that promises to deliver means to reach these goals, but higher education has yet to totally embrace the program. Here, we present practical examples on how to better teach the principles of PI in the context of the Bloom’s taxonomy and summarise the current industrial use and the future demands for PI, as a continuation of the topics discussed in Part 1. In the appendices, we provide details on the existing PI courses around the world, as well as teaching activities that are showcased during these courses to aid students’ lifelong learning. The increasing number of successful commercial cases of PI highlight the importance of PI education for both students in academia and industrial staff.

Abstract

In 2015 all the United Nations (UN) member states adopted 17 sustainable development goals (UN-SDG) as part of the 2030 Agenda, which is a 15-year plan to meet ambitious targets to eradicate poverty, protect the environment, and improve the quality of life around the world. Although the global community has progressed, the pace of implementation must accelerate to reach the UN-SDG time-line. For this to happen, professionals, institutions, companies, governments and the general public must become cognizant of the challenges that our world faces and the potential technological solutions at hand, including those provided by chemical engineering. Process intensification (PI) is a recent engineering approach with demonstrated potential to significantly improve process efficiency and safety while reducing cost. It offers opportunities for attaining the UN-SDG goals in a cost-effective and timely manner. However, the pedagogical tools to educate undergraduate, graduate students, and professionals active in the field of PI lack clarity and focus. This paper sets out the state-of-the-art, main discussion points and guidelines for enhanced PI teaching, deliberated by experts in PI with either an academic or industrial background, as well as representatives from government and specialists in pedagogy gathered at the Lorentz Center (Leiden, The Netherlands) in June 2019 with the aim of uniting the efforts on education in PI and produce guidelines. In this Part 1, we discuss the societal and industrial needs for an educational strategy in the framework of PI. The terminology and background information on PI, related to educational implementation in industry and academia, are provided as a preamble to Part 2, which presents practical examples that will help educating on Process Intensification.

Abstract

Molecular transport in porous media plays an essential role in heterogeneous catalysis. Here, we have studied a Polymer‐Membrane‐Catalyst Assembly (PCMA) system consisting of PET membranes with a well‐defined pore structure coated with thermo‐responsive polymer (poly(n‐isopropylacrylamide) or p‐NIPAM) coupled to an in‐situ ATR‐IR cell containing palladium supported on γ‐Al2O3. This PCMA model is designed to mimic the structure of a core‐shell catalyst coated with stimulus responsive polymer. At low temperatures (<32 °C), where p‐NIPAM is in its swollen state, the addition of polymer brushes caused a delay in CO chemisorption on Pd. Strikingly, when the polymer collapses (>32 °C), we observed faster CO−Pd saturation. Our multi‐physics model of the CO transport and chemisorption on the PCMA suggests that the delay is caused by the strong affinity of the CO molecules with the polymer brushes. When stimulus responsive polymers are present, a complex interplay between diffusion and absorption determines the dynamic behavior of the system. Furthermore, we demonstrate that this behavior could be reversed by reducing the ratio of polymer inside the pores and the surface, in which the delay observed is now above the LCST. This new insights on the dynamics of transport, absorption, and chemisorption processes occurring on so‐called "nano‐reactors" provide new opportunities for developing new self‐regulating catalysts with faster transitions between ON‐ and OFF‐ states.

23. Polymer Induced Solvation Effects on Liquid Phase Catalytic Hydrogenations

Abstract

The effect of the solvent environment is important for the activity and selectivity of a catalytic reaction conducted in the liquid phase. One must carefully consider the potential interactions between the solvent molecules and the reacting species as these interactions can alter mass transfer rates, reaction kinetics, product selectivity, and catalyst stability as well as the properties of the solvent including density and viscosity. As a result, these so-called solvation effects can induce a significant change in the catalytic performance. However, finding the perfect “marriage” between the solvent, reaction, and catalyst is difficult as only a few solvents can deliver the desired performance. Essentially, the best solvents to stabilize the reactants and products in the bulk might not be the optimal solvation environment for the catalyst. A promising approach could be to decouple the local reaction environment of the active sites from that of the solvent in the bulk. This can be achieved with a polymer coating that can induce a solvation effect near the active site. In this thesis, a thermal-responsive polymer (p-NIPAM) that has a lower critical solution temperature (LCST) has been employed as polymer coating on a model Pd/SiO2 catalyst to validate this concept. The effect of the solvent and polymer-induced solvation effects on the reaction selectivity and activity have been studied using the nitrite and nitrobenzene hydrogenation reactions as probe chemistries.

24. Utilization of p-nipam polymeric brushes in the development of thermo-responsive catalytic systems : a study of the effects of self-regulating polymers on molecular transport and reaction kinetics

Abstract

This thesis presents a proof of concept of self-regulating mechanism by a heterogeneous catalyst in combination with stimuli responsive polymer. These polymers have the unique ability to reversibly change conformation from a swollen to a collapsed state in response to an environmental stimulus (e.g. temperature or pH). The conformation change of the polymer could allow to locally adjust the molecular diffusion of reactants, thereby changing the catalytic activity autonomously. Since the reaction will be intrinsically manipulated, implementing this concept to industrial processes will potentially alleviate the need for using external measures to control the reaction rate, such as passive cooling or using inert dilutants. Thus far, the self-regulating mechanism using stimuli responsive polymers has never been demonstrated for heterogeneous catalysis. Instead, an external stimulus is applied to alter the catalyst activity depending on the polymer conformational state when polymeric brushes are coated on a nano cluster. In the presence of a thermo-responsive polymer, such as poly(n-isopropylacrylamide) (p-NIPAM), the increase of temperature causes the polymeric brushes to collapse after surpassing a certain temperature, the so called Lower Critical Solution Temperature (LCST). Consequently, the change in conformation resulted in a decrease on the reaction rate, due to the partial blockage of the diffusion path of the reactants. These idealized systems demonstrate that thermo-responsive materials can be used to control molecular transport of reactants. However, there is still a significant research gap concerning the development of more practical catalysts that can have this stimulus-responsive behaviour under industrially relevant condition.
