We develop a facile method to prepare cobalt phosphate nanoparticles coated by N-doped carbon layers for highly active and stable OER electrocatalyst.
Efficient and durable oxygen evolution reaction (OER) catalysts are highly required for the cost-effective generation of clean energy from water splitting. For first time, an integrated OER electrode based on one-step direct growth metallic iron-nickel sulfide nanosheets FeNi alloy foils (denoted as FeNi3 S2 /FeNi) is reported, origin enhanced activity uncovered in combination with theoretical experimental studies. The obtained /FeNi exhibits catalytic long-term stability toward strong...
The synergistic regulation of the electronic structures transition-metal oxide-based catalysts via oxygen vacancy defects and single-atom doping is efficient to boost their evolution reaction (OER) performance, which remains challenging due complex synthetic procedures. Herein, a facile defect-induced in situ deposition strategy developed anchor atomically dispersed Ru onto vacancy-rich cobalt oxides (Ru/Co3O4–x) based on spontaneous redox between Ru3+ ions nonstoichiometric Co3O4–x....
Cobalt-rich cobalt phosphide catalysts on foils as integrated bifunctional electrodes have been developed and display outstanding performances towards overall water splitting.
Electrochemical water splitting is an important process to produce hydrogen and oxygen for energy storage conversion devices. However, it often restricted by the evolution reaction (OER) due its sluggish kinetics. To overcome problem, precious metal oxide-based electrocatalysts, such as RuO2 IrO2, are widely used. The lack of availability high cost metals compel researchers find other resources development cost-effective, environmentally friendly, earth-abundant, nonprecious electrocatalysts...

Highly monodisperse Ni NPs in UiO-66 give both excellent activity and selectivity for CO<sub>2</sub> methanation at low temperatures.
Efficient and low-cost transition-metal (TM)-based electrocatalysts have been of great importance for producing hydrogen (H2) oxygen (O2) via electrocatalytic water (H2O) splitting to ameliorate global energy environmental problems. However, TM-based materials generally suffer from unsatisfactory activity because their relatively low conductivity unregulated electronic structure. Therefore, the structure engineering is an efficient strategic approach enhance catalytic performances...

Significant challenges remain for developing efficient catalysts in an electrochemical multielectron CO2 reduction reaction (CO2RR), which usually suffers from poor activity and selectivity. Motivated by the recent experimental progress fabricating dual-metal atom (DMACs) N-doped graphene materials (graphene-N6V4; N: nitrogen V: vacancy), we sampled eight types of homonuclear (N6V4-M2, M = Cr, Mn, Fe, Co, Ni, Cu, Pd, Ag) 28 heteronuclear (N6V4-M1M2) to study CO2RR via first-principles...
