Summary: Since its inception, green chemistry has been the guiding principle for reducing pollution and protecting the environment. The twelve Principles of Green Chemistry provide tools for designing sustainable transformations and implementing industrial processes with renewable feedstocks. By utilizing clean separation processes and non-toxic products, these processes aim to minimize waste production. Biocatalysts synthesized according to the principles of green chemistry and circular economy play a crucial role in achieving the United Nations' 17 Sustainable Development Goals, leading to a sustainable future by reducing resource consumption and environmental impact.

Summary: Single-atom catalysts (SACs) with the advantages of homogeneous and heterogeneous catalysts have become a hot-spot in catalysis field. However, the lack of metal-metal bond in SACs limits their hydrogenation activity. This study proposes a catalyst, Ir1+NPs/CMK, which combines single iridium atoms and nanoparticles to boost the catalytic activity of quinoline hydrogenation, and achieves significant improvement in reactivity.

Summary: The present study evaluated the synergistic effect of imidazolium-based ionic liquids (IL) in the preparation and immobilization of Burkholderia cepacia lipase, using a hybrid support of poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) and silica. The results showed that the use of IL significantly increased the immobilization yield of the lipase and caused changes in the morphological structure of the hybrid support. Transesterification reactions using the immobilized lipase showed high conversion rates under specific conditions.

Summary: A phosphorous modification method was reported to improve the HDS activity and selectivity of CoMo/δ-Al2O3 catalyst simultaneously. The enhanced HDS performance was attributed to weakened metal-support interaction, resulting in the formation of a large amount of active (Co)MoS2 phase with higher stacking and Co promotion degree. The improved Co promotion degree promotes the HDS activity, while increased stacking decreases the olefin hydrogenation activity. When applied to a real FCC naphtha, the sulfur content could be reduced to 5.4 ppm with only a total research octane number loss of 0.7 units.

Summary: In this work, a method to improve lithium metal anodes is proposed, where ZnO sites are introduced into carbon shell/carbon cloth to reduce the nucleation barrier of lithium deposition. The 3D current collector alleviates the volume change during lithium plating/stripping and the combination of ZnO/C and 3D carbon cloth contributes to uniform lithium plating/stripping. The modified carbon cloth electrodes demonstrate high Coulombic efficiency of 99.34% even under high areal capacity.
