Summary: Utilizing earth-abundant seawater over scarce freshwater for hydrogen fuel production via water electrolysis is a promising strategy. However, serious anodic corrosion due to chloride oxidation reaction hampers the stability of the electrolyzer. The development of a bifunctional catalyst, such as the nanorod array-based hierarchical NiO microspheres, can greatly enhance the selective seawater splitting and corrosion resistance.

Summary: Using seawater instead of freshwater for hydrogen fuel production via water electrolysis is a promising strategy, but the corrosion caused by chloride oxidation reaction hampers the overall stability of the electrolyzer. A bifunctional catalyst, NRAHM-NiO, developed by morphology engineering, shows outstanding catalytic activity for highly selective seawater splitting. With a small cell voltage, the catalytic activity is superior to benchmark systems and demonstrates specific stability and selectivity without forming chlorine species. The integrated photolysis system shows a 9.9% solar-to-hydrogen efficiency.

Summary: This study demonstrates the importance of tuning heteroatom doping and graphitic structure in carbon materials for achieving highly accessible graphitic structures in advanced potassium ion batteries. The research shows that the potassium storage mechanism in N,S-CNSs is described by an adsorption-insertion mechanism, where the highly disordered/pseudo-graphitic carbon structure contributes to a high-potential sloping region by adsorption and the graphitic carbon structure contributes to a low-potential plateau region by insertion. By tuning the adsorption and insertion mechanisms, N,S-CNS-1200 with a highly developed graphitic structure exhibits satisfactory reversible specific capacity and high capacity retention after 1000 cycles.
