Abstract Stable non‐noble metal electrocatalysts are of essential importance for industrial water electrolysis. Powdery loaded on current collectors by binders often designed, but easily fall off due to strong attack bubbles at an large density (>400 mA cm −2 ). A novel strategy is developed construct a self‐supported dual‐phase porous Co 2 P–Co 3 O 4 film oxygen evolution reaction (OER) and micro‐nanoporous P hydrogen (HER) based the electrodeposition single‐phase CoP gas–liquid–solid...
Hierarchically porous films constructed on gas–liquid–solid three-phase interface by electrodeposition are reviewed. The formation mechanism of structure is discussed. electrochemical properties as electrode materials for energy application highlighted.
Iron group metals chalcogenides, especially NiS, are promising candidates for K-ion battery anodes due to their high theoretical specific capacity and abundant reserves. However, the practical application of NiS-based is hindered by slow electrochemical kinetics unstable structure. Herein, a novel structure Ni3 S2 -Ni hybrid nanosphere with intra-core voids encapsulated N-doped carbon shells (Ni3 -Ni@NC-AE) constructed, based on first electrodeposited NiS particles, dopamine coating outer...
The surface structures of the electrodeposited NiMo films from compact to porous structure are adjusted by combination gravity acceleration and electrodeposition time. evolution mechanism is discussed based on protrusion growth theory. dependence catalytic activity for hydrogen reaction (HER) studied. results indicate that layer first electrodeposited, then protrusions formed. Finally, rapidly grow form a structure. It found only under normal condition due long induced time formation. Under...

The prepared LDHQDs/NiCoP NA demonstrates outstanding overall water splitting performance. coupling effect between the NiCoP and LDHQDs facilitates efficient electron transport modulates adsorption desorption of intermediates.
The structure of Ni films is essential to their electrocatalytic performance for hydrogen evolution reaction (HER). pH value and EDTA (ethylene diamine tetraacetic acid) additive are important factors the control electrodeposited metal due adjustment electrocrystallization side reactions. structures from 3D (three-dimensional) porous compact flat by adjusting solution values or adding EDTA. It found that when increases 7.7 8.1, change with many protrusions. Further increasing 0.1 M causes...
Porous metal films directly electrodeposited by using hydrogen bubbles as template have attracted widely attentions. However, the formation and evolution mechanism of pores are unclear. Lots produced during electrodeposition, which will affect surface structure porous films. Wettability is an intrinsic property to adjust bubble separation expected change film. In paper, Ni was used a model, effects wettability on characteristics were studied. The analyzed based COMSOL simulation. results...
