Abstract:This review outlines the strategies and challenges of the state-of-the-art non-precious group metal-based catalysts toward water electrolysis.
“…Water electrolysis to produce hydrogen, a new and clean energy source, can help solve the current energy crisis and remediate our environment. [1][2][3][4] As its two half reactions, the four-electrontransfer oxygen evolution reaction (OER) at the anode is kinetically more sluggish than the two-electron-transfer hydrogen evolution reaction (HER) at the cathode, and thus mainly determines the efficiency of water splitting. [5][6][7][8][9][10] A high overpotential is usually required to drive the OER, resulting in large energy loss.…”
Cheap and highly efficient electrocatalysts are needed to expedite the sluggish oxygen evolution reaction (OER) in water electrolysis to provide clean and sustainable hydrogen energy. In this work, systematic first-principles...

“…Electrocatalytic hydrogen generation from water splitting is a promising technology for sustainable energy storage, 1–3 which consists of a hydrogen evolution reaction at the cathode, and an oxygen evolution reaction (OER) or a chlorine oxidation reaction (COR) at the anode (eqn (1)–(3)). 4–6 2H 2 O → O 2 + 4H + + 4e − , E ° = 1.23 V2Cl − → Cl 2 + 2e − , E ° = 1.36 VCl − + H 2 O → HOCl + H + + e − , E ° = 1.49 V…”
Individual cobalt hydroxides with clearly identified crystal structures can aid in discerning the relationship between the crystal structure and catalytic activity. Herein, the crystal structure of α-Co(OH)2 and its transformations...
“…Hydrogen (H 2 ) is seen as one of the most essential energy sources in the 21st century due to its advantages of high caloric value and zero carbon emissions. [1][2][3] However, the main source of hydrogen is still conventional fossil fuel reforming. In contrast, electrocatalytic hydrogen production by combining renewable energy with water splitting is considered one of the most promising methods for hydrogen production.…”
Developing efficient and durable samples for electrocatalytic monolithic hydrolysis is a tough but rewarding task. Herein, Ru, B Co-doped Ni2P/Ni5P4 nanoparticles (Ru/B-Ni2P/Ni5P4) is obtained by a facile and time-saving approach...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
