Summary: The current physicochemical methods for decolorizing toxic synthetic dyes are not sustainable and have limitations, such as high costs and sludge production. Biocatalysis, using microbes and/or their enzymes, offers a cost-effective, versatile, and environmentally-friendly alternative. Enzymes like laccases, azoreductases, and peroxidases can be used for dye degradation, with the potential to convert toxic dyes into less harmful byproducts. Immobilized cells or enzymes provide advantages in terms of stability, reusability, and longer lifespans, making them promising for the treatment of textile dye effluents. Packed bed reactors are the most efficient and cost-effective heterogeneous biocatalytic reactors for dye decolorization.

Summary: An ultra-highly active Ni-MOF-5 catalyst with high Ni loading was synthesized by replacing Zn2+ with Ni2+ in MOF-5 through a facile one-pot co-precipitation method. The catalyst achieved an ethylene turnover frequency of 352,000 h(-1), far exceeding the activities of all reported heterogeneous catalysts. The high catalytic performance can be attributed to the high Ni loading and full exposure structure of Ni-MOF-5.

Summary: Lithium-oxygen (Li-O2) batteries are considered as the next generation for energy storage systems due to higher theoretical energy density. However, the high charge overpotential caused by insulated Li2O2 results in low energy efficiency and poor battery performance. Designing noble metal-based catalysts can be an effective strategy to develop high-performance Li-O2 batteries. The charge mechanism for noble metal-based catalysts is still unclear and contradictory.

Summary: Iron-mediated divergent reductive coupling reactions of heteroarenes with alkenes have been developed. By switching the substituent site at the C2 and C4 positions of quinolines, either C2 Minisci alkylation or C4 reductive alkylation could be achieved. These approaches feature mild conditions and sensitive functional group tolerance, which enables the functionalization of natural products and medicines. Mechanism investigation revealed that Fe(dibm)(3) would be a dual promoter for both alkyl radical transfer and generation of the more reactive hydrogen donor Ph(RO)SiH2.
