Defect-derived surface phosphorus vacancies on ultrathin Rh2P nanowires break the monogeneity and atomic regularity of thermodynamically stable P-terminated surfaces, which can create additional Rh sites to act as exclusive H adsorption sites and diminish the inhibition effect of the interfacial water network to achieve drastically improved alkaline HOR electrocatalysis.

利用缺陷衍生的磷空位打破 Rh2P 纳米催化剂的表面原子同质性,实现高效碱性氢氧化



超薄Rh 2 P纳米线上的缺陷衍生的表面磷空位打破了热力学稳定的P端表面的单质性和原子规律性,这可以产生额外的Rh位点作为​​排他的H吸附位点,并减弱界面水网络的抑制作用显着改善碱性 HOR 电催化能力。
