“…Heterostructure engineering is an effect approach for strengthening the catalytic capabilities of the materials by forming properly aligned materials pairs, such as 2D‐2D heterostructures and core‐shell structures. [ 171–173 ] 2D metal‐based (hydr)oxide nanosheets can hybridize with other materials to form heterostructures, such as carbon materials, [ 174–178 ] metals, [ 179–183 ] metal (hydr)oxides, [ 24,184–188 ] metal sulfides, [ 189,190 ] in which the formation of unique interfacial chemical states can modify the electronic structure to improve the electrochemical abilities of the materials. [ 83 ] There are two major types of 2D‐2D heterostructures, the one is the assembly of two different 2D nanostructures in the manner of layer‐by‐layer, the other is the side‐by‐side assembly of two 2D nanomaterials jointing by edges.…”

2D metal (hydr)oxide nanosheets have captured increasing interest in electrocatalytic applications aroused by their high specific surface areas, enriched chemically active sites, tunable physiochemical properties, etc. In particular, the electrocatalytic reactivities of materials greatly rely on their surface electronic structures. Generally speaking, the electronic structures of catalysts can be well adjusted via controlling their morphologies, defects, and heterostructures. In this Review, the latest advances in 2D metal (hydr)oxide nanosheets are first reviewed, including the applications in electrocatalysis for the hydrogen evolution reaction, oxygen reduction reaction, and oxygen evolution reaction. Then, the electronic structure–property relationships of 2D metal (hydr)oxide nanosheets are discussed to draw a picture of enhancing the electrocatalysis performances through a series of electronic structure tuning strategies. Finally, perspectives on the current challenges and the trends for the future design of 2D metal (hydr)oxide electrocatalysts with prominent catalytic activity are outlined. It is expected that this Review can shed some light on the design of next generation electrocatalysts.

Evidence by selected area diffraction patterns shows the successful preparation of large area (cm × cm) MoS2/graphene heterojunctions in coincidence of the MoS2 and graphene hexagons (superlattice). The electrodes of MoS2/graphene in superlattice configuration show improved catalytic activity for H2 and O2 evolution with smaller overpotential of +0.34 V for the overall water splitting when compared with analogous MoS2/graphene heterojunction with random stacking.

“…Molybdenum (Mo), as the earth‐abundant transition metal, has shown unique physicochemical properties due to the similar d‐electrons structure with novel metal Pt. [ 37 ] Mo‐based materials, such as molybdenum oxide (MoO 2 ), [ 38 ] molybdenum disulfide (MoS 2 ), [ 16 ] molybdenum nitride (MoN), [ 39 ] molybdenum carbide (Mo x C), [ 40 ] and molybdenum phosphide (MoP), [ 41 ] have been investigated as the promising candidates for energy conversion. Among them, owing to the similar d‐band electronic density of metal Pt, molybdenum carbide has long been expected to be effective non‐Pt electrocatalysts for electrochemical energy conversion due to its high electrical conductivity and optimal intermediates‐adsorption properties.…”

Molybdenum carbide (MoxC)‐based nanomaterials have shown competitive performances for energy conversion applications based on their unique physicochemical properties. A large surface area and proper surface atomic configuration are essential to explore potentiality of MoxC in electrochemical applications. Although considerable efforts are made on the development of advanced MoxC‐based catalysts for energy conversion with high efficiency and stability, some urgent issues, such as low electronic conductivity, low catalytic efficiency, and structural instability, have to be resolved in accordance with their application environments. Surface and interface engineering have shown bright prospects to construct highly efficient MoxC‐based electrocatalysts for energy conversion including the hydrogen evolution reaction, oxygen evolution reaction, nitrogen reduction reaction, and carbon dioxide reduction reaction. In this Review, the recent progresses in terms of surface and interface engineering of MoxC‐based electrocatalytic materials are summarized, including the increased number of active sites by decreasing the particle size or introducing porous or hierarchical structures and surface modification by introducing heteroatom(s), defects, carbon materials, and others electronic conductive species. Finally, the challenges and prospects for energy conversion on MoxC‐based nanomaterials are discussed in terms of key performance parameters for the catalytic performance.
