While the mild production of syngas (a mixture of H2 and CO) from CO2 and H2O is a promising alternative to the coal‐based chemical engineering technologies, the inert nature of CO2 molecules, unfavorable splitting pathways of H2O and unsatisfactory catalysts lead to the challenge in the difficult integration of high CO2 conversion efficiency with produced syngas with controllable H2/CO ratios in a wide range. Herein, we report an efficient plasma‐driven catalytic system for mild production of pure syngas over porous metal–organic framework (MOF) catalysts with rich confined H2O molecules, where their syngas production capacity is regulated by the in situ evolved ligand defects and the plasma‐activated intermediate species of CO2 molecules. Specially, the Cu‐based catalyst system achieves 61.9 % of CO2 conversion and the production of pure syngas with wide H2/CO ratios of 0.05 : 1–4.3 : 1. As revealed by the experimental and theoretical calculation results, the in situ dynamic structure evolution of Cu‐containing MOF catalysts favors the generation of coordinatively unsaturated metal active sites with optimized geometric and electronic characteristics, the adsorption of reactants, and the reduced energy barriers of syngas‐production potential‐determining steps of the hydrogenation of CO2 to *COOH and the protonation of H2O to *H.

Ambitions towards a circular economy are increasingly vocalised across academia, policymaking and industry. The endeavour of realising these ambitions provides major opportunities and challenges in chemical engineering, and requires a tremendous roll-out of new technologies. This perspective highlights the suitability of chemical looping as a technology platform to contribute to the valorisation of material streams that are currently not used to their full potential, termed low-grade resources. Such material streams offer significant opportunities to minimise CO2 emissions and accelerate towards a circular materials economy. Apart from defining and identifying low-grade streams, both calorific and non-calorific, a non-exhaustive overview of such streams is provided. Based on a selection of case studies focusing on steel mill gases, bauxite residue, pyrite cinder, calcium carbide slag and automotive shredder residue, it is posited that the characteristics and flexibility of the chemical looping approach offer ample possibilities to efficiently reuse low-grade streams and minimise their environmental impact. Finally, an outlook on chemical looping as a technology platform and its possible role in the drive towards circularity is given, with attention for the roles of industrial, academic and governmental stakeholders. In order to assess the suitability of a chemical looping process for valorising low-grade resources, the importance of holistic technology investigations is stressed, taking into account technical, economic, ecological and societal considerations.

A study of Andean cattle skin was performed to determine the variation of skin substance (SP) produced by lime and sodium sulfide during the Liming and Calera stages using four different treatments (T). According to the ASTM D 2868-17, it is important to characterize the raw materials, followed by the tanning processes until obtaining samples of Wet Blue leather. Besides SP analysis and statistical treatment of the obtained data, sensory and physical-mechanical tests were carried out in the post-tanning stages. The results showed that SP at T1 (2.0% lime-2% Na2S) and T2 (2.7% lime-2% Na2S) produced the highest values; 79.5% and 79.3% respectively; with T3 (3.4% lime-2 % Na2S) and T4 (4.1% lime-2% Na2S) yielding 68.4% and 76.1%, respectively. The statistical analysis of the data evidenced that there is no significant differences between the means of T1 and T2. The results of the physical-mechanical and sensory tests directly relate to the trend of SP consumption in each treatment. The study carried out is aimed to recognize the direct relationship between the skin substance obtained in each treatment and the final product manufactured by the company, referred to the variability of the product to be obtained.

In the coming years, multipurpose catalysts for delivering different products under the same chemical condition will be required for developing smart devices for industrial or household use. In order to design such multipurpose devices with two or more specific roles, we need to incorporate a few independent but externally controllable catalytically active centers. Through space crystal engineering, such an externally controllable multipurpose MOF-based photocatalyst could be designed. In a chemical system, a few mutually independent secondary reaction cycles nested within the principal reaction cycle can be activated externally to yield different competitive products. Each reaction cycle can be converted into a time crystal, where the time consuming each reaction step could be converted as an event and all the reaction steps or events could be connected by a circle to build a time crystal. For fractal reaction cycles, a time polycrystal can be generated. By activating a certain fractal event based nested time crystal branch, we can select one of the desired competitive products according to our needs. This viewpoint intends to bring together the ideas of (spatial) crystal engineering and time crystal engineering in order to make use of the time–space arrangement in reaction–catalysis systems and introduce new aspects to futuristic chemical engineering technology.
