Implementing the dual-ligand strategy, a microporous Zn-based MOF 1 with nitro and amino groups was effectively produced. The activated interconnected pores of 1 exhibited high C2H2 uptake capacity and preferential adsorption behaviour for C2H2 over CO2, as identified by the experiments and simulations. This work provides a new approach for designing and synthesizing the MOFs with desired structures and properties by optimizing their pore environment via the dual-ligand strategy.

Compared to conventional thermal-driven fixation, the light-assisted CO2 fixation into useful chemicals represents a viable strategy for environmental restoratio n and energy sustainability. Hence, in this work, the type of linker was tuned to control the structure and topology of metal–organic frameworks (MOFs), resulting in a diversity of pore networks ranging from two-dimensional (2D) microporous channels (NWU-Cd1, 2) to three-dimensional (3D) nanochannels (NWU-Cd3). Among them, NWU-Cd3 can be employed as a reducing agent to convert Ag-(I) ions to Ag(0) to generate Ag/NWU-Cd3 composite materials in situ due to its large pore size, high CO2 adsorption capacity, and redox activity. Ag/NWU-Cd3 can expand the absorption spectrum to the visible area, and it exhibits excellent photocatalytic activity with the yield of styrene carbonate up to 94.3% at light irradiation and room temperature, which is 5.2 times of that under dark conditions. Notably, each Ag NP of the MOF network functions concurrently as a photosensitizer (harvesting light and producing electrons) and a cocatalyst (serving as the Lewis acid). The plasmonic hot electrons can gather on the Ag NP surface under light irradiation and rapidly transfer to NWU-Cd3 to interact with CO2, resulting in activated CO2*. Simultaneously, the presence of Ag NPs provides an action site for epoxides and accelerates the ring-opening process, and thus, Ag/NWU-Cd3 displays high catalytic reactivity for CO2 cycloaddition under mild circumstances (25 °C, 1 atm). This research clarifies the conjunction of light and Ag NPs in accelerating CO2 conversion and offers a substitutable method to further devise effective heterogeneous catalysts for light-induced CO2 cycloaddition.

This paper focuses on pricing strategies, inventory policies for a supply chain when Radio Frequency Identification (RFID) technology is adopted to cope with inventory inaccuracy. The supply chain consists of one supplier and one retailer, in which the RFID tag price is shared between the supplier and the retailer. We present and compare the performance differences between a wholesale price contract and a consignment contract when the retailer is the Stackelberg leader and the supplier is the follower. Based on the optimal pricing and inventory decisions, an interesting observation of contract selection is that there are two critical values of inventory available rate such that when the inventory availability is less than the lower value, both the supplier and the retailer prefer a consignment contract; when the inventory availability is greater than the upper value, a wholesale price contract is their best choice; when the inventory availability is between the two values, the supplier prefers a wholesale price contract and the retailer prefers a consignment contract. Additionally, there exist threshold values of RFID tag price and sharing rate to determine the contract preference for the retailer. Furthermore, the profits of both the supplier and the retailer are independent of the RFID tag price sharing rate in a wholesale price contract, and the supplier has the incentive to invest in RFID tag cost in a consignment contract.
