Summary: Enzymatic catalysis has attracted interest from chemists due to its efficiency and selectivity, but the complexity and vulnerability of enzymes limit their application potential. Metal-organic frameworks (MOFs) integrate the structure and active sites of natural enzymes into porous solids, providing bioinspired heterogeneous catalysts with superior stability and customizable structures. This review comprehensively summarizes the advances of bioinspired MOFs for catalysis, discusses the design principles of various MOF-based catalysts, and explores their utility in different reactions. The advantages of MOFs as enzyme mimetics are highlighted, and potential solutions to current challenges in MOF catalysis are discussed.

Summary: Metal-complex-based materials with multiple active sites and well-defined lithium transport pathways have attracted great interest. However, their cycling and rate performances are still limited by structural stability and electrical conductivity. This study presents two hydrogen-bonded complex-based frameworks with excellent lithium storage capability. The remarkable lithium storage performance of these materials was attributed to the stable three-dimensional frameworks formed through multiple hydrogen bonds among mononuclear molecules, as revealed by kinetic analysis and DFT calculations.

Summary: Transition-metal phosphides (TMPs) are considered ideal electrocatalysts due to their abundant reserve, flexible composition, competitive activity, and excellent stability. However, TMPs still face challenges of poor electrical conductivity and agglomeration at high synthetic temperatures. This study successfully fabricated a series of nanostructured Ni2P@SNC using a one-step phosphorization of a well-designed Ni-MOF with red phosphorus as the P source. The optimal Ni2P@SNC-800 displayed excellent HER performance and long durability in both 1.0 M KOH and 0.5 M H2SO4 electrolytes, surpassing the performance of other heteroatom-free MOF-derived Ni2P. This work provides a facile approach for designing and synthesizing MOF-derived TMPs coated with a heteroatom-doped carbon matrix as highly active electrocatalysts.
