Constructing Nanoporous Ir/Ta2O5 Interfaces on Metallic Glass for Durable Acidic Water Oxidation

“…Metallic glasses (MG), known as amorphous alloys with uniform chemical composition and long-range disordered microstructure, are considered as one of the ideal dealloying precursors. [16,17] Constructing high-surface-area and highperformance catalysts on MG using corrosion engineering is simple to synthesize, efficient to adjust, easy to large-scale production. [18][19][20][21][22][23] For example, Ni 60 Pd 20 P 17 B 3 metallic glass underwent electrochemical dealloying to form a nanoporous palladium-rich nanorod, exhibiting potential in large-scale preparation.…”

Developing an FexCoyLaz-based amorphous aerogel catalyst for the oxygen evolution reaction via high throughput synthesis

“…[5][6][7] Numerous initiatives have been taken to further improve the catalytic activity of transition metal-based OER electrocatalysts, including morphological modication, defect engineering, doping, compositing, etc., which resulted in appealing catalytic capabilities. [8][9][10][11][12][13][14][15] The introduction of new elements has been found to be a highly effective strategy for enhancing catalytic activity. This is primarily attributed to two key mechanisms.…”

Electronic Redistribution Through the Interface: A Prodigy that Enhances Electrocatalysis

“…In view of the decreasing reserves of traditional fossil fuels and the imminent threat of global warming resulting from escalating carbon dioxide emissions, the scientific community has been prompted to explore alternative paths for fuel combustion that are both environmentally friendly and sustainable. [1][2][3] Hydrogen has been recognized as a very suitable alternative energy source due to its combustion byproduct consisting solely of water. Water electrolysis is often regarded as a highly promising and environmentally friendly method for producing hydrogen, as it does not release any carbon dioxide.…”
