Heteroatoms Fe, F co‐doped NiO hollow spheres (Fe, F‐NiO) are designed, which simultaneously integrate promoted thermodynamics by electronic structure modulation with boosted reaction kinetics by nano‐architectonics. Benefiting from the electronic structure co‐regulation of Ni sites by introducing Fe and F atoms in NiO , as the rate‐determined step (RDS), the Gibbs free energy of OH* intermediates...
Direct electrolysis of pH‐neutral seawater to generate hydrogen is an attractive approach for storing renewable energy. However, due to the anodic competition between the chlorine evolution and the oxygen evolution reaction (OER), direct seawater splitting suffers from a low current density and limited operating stability. Exploration of catalysts enabling an OER overpotential below the hypochlorite...
