Modulating the active sites of nickel phosphorous by pulse-reverse electrodeposition for improving electrochemical water splitting

Byung Keun Kim et al.

Summary: This study introduces pulse-reverse electrodeposition (PRED) as a method to improve the properties of nickel phosphorus (NiP) films and enhance the performance of hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). The research explores the effects of electrochemical parameters in PRED on HER and OER activities, revealing that changes in the dissolution step of PRED have opposite impacts on these two activities. The study shows that increased dissolution amount during PRED enhances OER while decreasing HER activity. Mott-Schottky analysis suggests that the improvement in HER activity by adopting PRED is due to an increase in the reactivity of active sites. In contrast, the increase in OER activity is attributed to an increase in the number of active sites on the surface of NiP films caused by excess dissolution during PRED. Surface analyses indicate that the opposite responses of HER and OER are caused by different factors; the uniform formation of NiP governs HER activity, while the removability of phosphate determines the exposure of OER-active Ni oxide phases.

Exclusive Strain Effect Boosts Overall Water Splitting in PdCu/Ir Core/Shell Nanocrystals

Menggang Li et al.

Summary: In this study, precise synthesis of PdCu/Ir core/shell nanocrystals was reported, which significantly boosted oxygen evolution reaction (OER) through the exclusive strain effect. The compressive strain in the Ir shell downshifted the d-band center and weakened the binding of the intermediates, leading to enhanced OER activity. The strained nanocrystals also exhibited improved hydrogen evolution reaction (HER) activity, making them excellent catalysts for overall water-splitting electrocatalysis.
