Lattice-disorder layer generation from liquid processing at room temperature with boosted nanointerface exposure toward water splitting

Abstract

The structural symmetry breaking of a highly crystalline substance towards non-crystal phase construction, particularly involving a self-healing process after crystalline grain destruction, is beset by difficulties and critical for water splitting.

Amorphous Co-Mo-B Film: A High-Active Electrocatalyst for Hydrogen Generation in Alkaline Seawater

“…The growing global energy crisis and environmental problems caused by the massive consumption of traditional non-renewable resources drive humans to explore eco-friendly and renewable energy, and hydrogen (H 2 ) is a desirable alternative to fossil fuels on account of its high calorific value and pollution-free features [ 1 , 2 , 3 , 4 ]. Water electrolysis technology provides a facile and sustainable route for the massive generation of high-purity H 2 [ 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. Nevertheless, large-scale water electrolysis would doubtlessly exacerbate the shortage of freshwater.…”

Recent progress on bulk Fe-based alloys for industrial alkaline water electrolysis

“…The catalytic performance is affected not only by the active sites but also by the conductivity and interface bonding strength. [177][178][179][180][181] In situ electrochemical activation can promote the surface of the substrates to transform into some oxides/(oxy)hydroxides, which are the active sites for the HER/OER, 182,183 causing high conductivity and excellent stability under high current densities. Hence, in situ electrochemical activation could enhance the catalytic performance of bulk Fe-based alloys by forming Fe(Ni) oxides/ (oxy)hydroxides.…”

Electronegativity-Induced Valence State Augmentation of Ni and Co through Electronic Redistribution between Co-Ni3N/CeF3 Interfaces for Oxygen Evolution Reaction

“…Hence, it is vital to develop viable and green energy sources to confront the ever-increasing usage of fossil fuels and environmental pollution. Electrochemical water splitting has been envisioned as a rapid, highly productive, and environmentally benign process for producing high-purity hydrogen. − In addition, the lousy kinetics of the anodic oxygen evolution reaction (OER) make it difficult to make progress in the field of water-splitting technology, which requires a significant overpotential in order to achieve the necessary current density. − While pricey metal oxides such as IrO 2 and RuO 2 demonstrate effective OER performance, their paucity, exorbitant prices, and poor stability limit their broad utilization. − The fabrication of highly active electrocatalysts based on earth-abundant elements would be a very promising answer to the aforesaid problems. From this perspective, non-noble metals (Ni, Co, and Fe) and their related sulfides, − oxides, − and phosphides − are being intensively explored as electrocatalysts for the OER.…”
