Hydrogen has been deemed as an ideal substitute fuel to fossil energy because of its renewability and the highest density among all chemical fuels. One most economical, ecofriendly, high-performance ways hydrogen production is electrochemical water splitting. Recently, 2D transition metal dichalcogenides (also known TMDs) showed their utilization potentiality cost-effective evolution reaction (HER) catalysts in electrolysis. Herein, recent representative research efforts systematic progress made TMDs are reviewed, future opportunities challenges discussed. Furthermore, general methods synthesizing materials introduced detail advantages disadvantages for some specific provided. This explanation includes several important regulation strategies creating more active sites, heteroatoms doping, phase engineering, construction heterostructures, synergistic modulation which capable optimizing electrical conductivity, exposure catalytic barrier electrode material boost HER kinetics.

Abstract Metal sites play an essential role in both electrocatalytic and photocatalytic energy conversion. The highly ordered arrangements of the organic linkers metal nodes as well well‐defined pore structures metal‐organic frameworks (MOFs) make them ideal substrates to support atomically dispersed (ADMSs) located their nodes, linkers, pores. Porous carbon materials doped with ADMSs can be derived from these ADMS‐incorporating MOF precursors through controlled treatments. These incorporated pristine MOFs MOF‐derived possess unique advantages over molecular or bulk metal‐based catalysts bridge gap between homogeneous heterogeneous for energy‐conversion applications.
