d-Band Center Engineering of Nickel Nanoparticles Accelerates Water Dissociation for Hydrogen Evolution in Neutral NaCl Solution.

While Pt is highly efficient for hydrogen evolution reaction (HER), its widespread use is limited by scarcity and high cost. Herein, a vertically aligned electrocatalyst is present comprising NiS nanotube arrays (NTAs) and Ni nanoparticles (NPs) (NiS/Ni NTAs) for neutral HER. In a neutral 4 wt.

Engineering antibonding orbital occupancy of NiMoO-supported Ru nanoparticles for enhanced chlorine evolution reaction.

Chlorine evolution reaction (CER) is crucial for industrial-scale production of high-purity Cl. Despite the development of classical dimensionally stable anodes to enhance CER efficiency, the competitive oxygen evolution reaction (OER) remains a barrier to achieving high Cl selectivity. Herein, a binder-free electrode, Ru nanoparticles (NPs)-decorated NiMoO nanorod arrays (NRAs) supported on Ti foam (Ru-NiMoO/Ti), was designed for active CER in saturated NaCl solution (pH = 2).

Enhancing Ru-Cl interaction via orbital hybridization effect in RuSnTi electrode for efficient chlorine evolution.

Chlorine evolution reaction (CER) is a commercially valuable electrochemical reaction used at an industrial scale. However, oxygen evolution reaction (OER) during the electrolysis process inevitably leads to the decreased efficiency of CER. It is necessary to improve the selectivity of CER by minimizing or even eliminating the occurrence of OER.
