Confining Pd Nanoparticles and Atomically Dispersed Pd into Defective MoO3 Nanosheet for Enhancing Electro- and Photocatalytic Hydrogen Evolution Performances

“…In recent years, interface engineering has achieved great success in the direction of electrocatalysis, − which can combine two or more substances of different phases by different methods to form an active interface filled with active sites, thereby improving the exposure of the active sites. In addition, the interface of the connection ensures a rapid ion or electron transfer of the electrocatalyst, further increasing the catalytic rate and achieving better catalytic performance. − For example, Zhang’s group combined MoO 3 and 1T′-MoS 2 for better catalytic performance . Nevertheless, their HER performance is still far less than that of noble metals.…”

Defect‐Rich Heterogeneous MoS2/NiS2 Nanosheets Electrocatalysts for Efficient Overall Water Splitting

“…[16,17] In particular, in situ growing nanosheet nanostructures on conductive substrates, such as Ni foam, carbon cloth, and stainless steel, could supply the efficient pathways for charge transport and provide open channels for rapid release of gas bubbles during OER or HER process. [21,22] The interface engineering could be beneficial to enrich the active sites and promote the electronic transfer, and thus boost the sluggish water splitting efficiency.

A 3D hierarchical network derived from 2D Fe-doped NiSe nanosheets/carbon nanotubes with enhanced OER performance for overall water splitting

“…To address these issues, the synthesis of low-cost and high-performance catalysts derived from non-precious metal nanomaterials is of great significance for hydrogen production. 6,7 Recently, three-dimensional (3D) transition Ni metal-based materials such as layered double hydroxide, 8,9 oxides, 10 phosphides, 11–13 and dichalcogenides 14 have attracted a great deal of attention as effective oxygen evolution catalysts, due to their unique physicochemical characteristics. Particularly, nickel selenide materials have recently aroused great interest owing to their simplicity of fabrication and superior electrocatalytic behaviors to hydroxides or oxides.…”
