Electrocatalytic water splitting for hydrogen production is an appealing strategy to reduce carbon emissions and generate renewable fuels. This promising process, however, is limited by its sluggish reaction kinetics and high-cost catalysts. The two-dimensional (2D) transition metal dichalcogenides (TMDCs) have presented great potential as electrocatalytic materials due to their tunable bandgaps, abundant defective active sites, and good chemical stability. Consequently, phase engineering, defect engineering and interface engineering have been adopted to manipulate the electronic structure of TMDCs for boosting their exceptional catalytic performance. Particularly, it is essential to clarify the local structure of catalytically active sites of TMDCs and their structural evolution in catalytic reactions using atomic resolution electron microscopy and the booming in situ technologies, which is beneficial for exploring the underlying reaction mechanism. In this review, the growth regulation, characterization, particularly atomic configurations of active sites in TMDCs are summarized. The significant role of electron microscopy in the understanding of the growth mechanism, the controlled synthesis and functional optimization of 2D TMDCs are discussed. This review will shed light on the design and synthesis of novel electrocatalysts with high performance, as well as prompt the application of advanced electron microscopy in the research of materials science.

Electrocatalytic materials with different morphologies,sizes,and components show different catalytic behavior in various heterogeneous catalytic *** has been proved that the catalytic properties of these materials are strongly influenced by several factors at different levels,including the electrode morphology,reaction channels,three-phase interface,and surface active *** developments of mesoscience allow one to study the relationship between the apparent catalytic performance of electro-catalytic materials with these factors from different *** this review,following a brief introduction of new mesoscience,we summarize the effect of mesoscience on electrocatalytic material design,including modulating the geometric and electronic structures of materials focusing on morphology(particulate,fiber,film,array,monolith,and superlattice),pore structure(microporous,mesoporous,and hierarchical),size(single atoms,nanoclusters,and nanoparticles),multiple components(alloys,heterostructures,and multiple ligands),and crystal structures(crystalline,amorphous,and multiple crystal phases).By evaluating the electrocatalytic performance of catalytic materials tuned at the mesoscale,we paint a picture of how these factors at different levels affect the final system performance and then provide a new direction to better understand and design catalytic materials from the viewpoint of mesoscience.
