Summary: Carbon dioxide cycloaddition into fine chemicals is a promising technology for solving energy crisis and environmental issues. This study investigates the effects of metal type on the performance of CO2 cycloaddition using isostructural MOF-919-Cu-Fe and MOF-919-Cu-Al as models. The results reveal that MOF-919-Cu-Fe with exposed Fe and Cu Lewis acid sites exhibits significantly higher conversion and selectivity compared to MOF-919-Cu-Al. The mechanism suggests that the exposed Fe3+ sites facilitate the ring opening of epoxide and CO2 activation, promoting the CO2 cycloaddition reaction.

Summary: Poly(ionic liquid)s (PILs) have gained attention due to their excellent properties similar to ionic liquids and polymers. However, their applications are limited due to blockage of active sites by abundant and flexible ions. This study reports the synthesis of a PIL/graphene composite catalyst (iPOP-ZnTPy@GNFs) with controlled particle size and dispersion state. The iPOP-ZnTPy@GNFs exhibited higher catalytic activity in the CO2 cycloaddition reaction and efficiently converted epoxides to cyclic carbonates at room temperature or atmospheric pressure. The catalyst also showed excellent substrate scope, catalytic diversity, and reusability.

Summary: In this study, a layered nitro-halide beta-ZrNBr with a narrow band gap and low defect density was synthesized. The material exhibited multifunctionalities for photocatalytic water reduction, water oxidation, and CO2 reduction under visible-light irradiation. The formation of anion vacancies in the nitro-halide photocatalyst was inhibited, leading to improved performance. Furthermore, exfoliation into nanosheets promoted carrier transfer and charge separation. This work expands the territory of functional photocatalysts and provides a new avenue for efficient artificial photosynthesis.

Summary: We present a cost-effective, easy-to-operate, and environmentally friendly magnetic grinding synthesis process for producing non-toxic copper sulfide-based composites with photocatalytic activity. CuS/ZnS and CuS/CdS composites were successfully synthesized without the need for additives or solvents. The composites exhibited high photocatalytic activity in the degradation of dyes under visible irradiation, with degradation efficiencies exceeding 95% for methylene blue and rhodamine B, and over 85% for methyl orange. The CuS/ZnS and CuS/CdS composites demonstrated superior photocatalytic performance compared to pure metal sulfides, and showed good stability in the degradation of organic dyes. The main reactive species responsible for the degradation were identified as photogenerated hydroxyl radicals (OH). Reasonable photocatalytic reaction mechanisms were proposed to explain the processes involved in the CuS/ZnS and CuS/CdS composites' photocatalytic activity.

Summary: Supramolecular chemistry has become an interdisciplinary discipline which includes chemistry, physics, and biology. Metal-organic molecular containers (MOMCs) have received considerable attention due to their rich chemical properties and wide potential applications. In this paper, selected examples of coordination-driven metal-organic supramolecular systems are reviewed, focusing on self-assembly construction and various applications. The different choice of organic ligands with flexible backbones during construction leads to diverse configurations compared to rigid ligands, providing a different perspective on metal-organic system construction.
