Summary: Microbes can offer a more sustainable and energy-efficient option for food and nutrient production compared to plants and animals, but it requires intensive energy inputs. Researchers have discovered that hydrogen-oxidizing carbon and nitrogen-fixing microorganisms can overproduce vitamin B2 using a mixture of gases. This method has shown promising results in maintaining high production of vitamin B2 under hybrid inorganic-biological conditions.

Summary: Fe/Ni-N-C materials were successfully constructed and evaluated in a typical H cell, showing a highest CO Faradaic efficiency of 92.9% and a largest turnover frequency of 10.77 x 103 h-1 at - 0.677 V vs. RHE. When transferred to a larger-scale continuous flow cell, Fe/Ni-N-C exhibited higher current density and FECO with robust durability, preserving over 89% of FECO after 40 hours of electrolysis. The synergetic effects of binary metals effectively enhanced the charge transfer rate and provided favorable kinetics. Furthermore, an aqueous Zn-CO2 battery assembled with Fe/Ni-N-C as the cathode demonstrated excellent charge-discharge cycle stability, serving as the electricity supply for ECR.

Summary: Photocatalysis is a promising technology in the fields of energy conversion/storage and environment purification. However, the low catalytic activity of individual photocatalysts hinders their utilization. Covalent organic framework (COF)-semiconductor-based composite photocatalysts provide a feasible route to achieve high-performance photocatalytic reactions. In this review, the synthetic strategies and performance of COF-semiconductor-based heterostructures in different photocatalytic reactions are comprehensively discussed. The potential and challenges of realizing COF-semiconductor-based heterostructures with simple synthesis methods, diverse functions, high performance, and well-defined reaction mechanisms are also presented.

Summary: In this study, a bimetallic coordination polymer of ZnCoBTC was synthesized using the MOF-on-MOF strategy, where both Co(II) and Zn(II) cations exhibit the same coordination environment. By applying an electric potential, the designed bimetallic MOF precursor can be degraded into active species for efficient oxygen evolution reaction (OER). The ZnCoOxHy nanosheet showed excellent OER performance, indicating the potential use of metals with the same coordination environment as efficient catalysts for future energy applications.

Summary: We investigated the reaction of S(P-3) with 1,3-butadiene and isoprene under single collision conditions using crossed-beam velocity map imaging and high-level ab initio/transition state theory modeling. In the reaction with butadiene, we observed H and H-2 loss from the initial adduct, while in the reaction with isoprene, we observed H loss and methyl loss. Theoretical calculations confirmed that these losses were due to intersystem crossing to the singlet surface forming long-lived intermediates. The results for S(P-3) + 1,3-butadiene showed direct cyclization to the aromatic product and yielded few bimolecular product channels, which was in contrast to the analogous O(P-3) reaction.

Summary: Coordination polymers (InOF-25/26) are transformed into nanostrip-like crystalline particles to synthesize phosphorus-doped multi-defective carbon nanoribbons for anchoring iron phthalocyanine. The resulting FePc-Fe2P@25-CNR electrocatalyst exhibits excellent performance in oxygen reduction reaction (ORR) and shows stability in Zn-air batteries. The improved ORR performance is attributed to phosphating the carbon surface, enhancing bonding with transition metal phthalocyanines, and inducing charge migration.

Summary: Currently, porous metal-organic frameworks (MOFs) are widely used as precursors for the synthesis of porous carbon nanomaterials (CNMs) due to their remarkable properties such as large surface area, high porosity, and excellent stability. However, there is a lack of systematic classification and summarization of the different types of MOF-derived CNMs. In this review, we classify MOF-derived CNMs based on dimension and provide a comprehensive overview of recent advances in their controlled synthesis. The review also highlights the influence of material morphology and composition on the performance of MOF-derived CNMs in popular applications such as heterogeneous catalysis, fuel cells, and sensors.
