Foreign transition metals are doped into the hexagonal nickel phosphide structure through a simple and facile bottom-up wet-chemical synthesis process via stabilization with oleylamine, trioctylphosphine (TOP), and trioctylphosphine oxide (TOPO): the as-prepared transition metal-doped nickel phosphide nanoparticles show a high level of doping but create no significant distortion of the crystal structure and morphology against pristine nickel phosphide nanoparticles, which exhibit excellent activity in the electrochemical oxygen evolution reaction (OER), having overpotential as small as 330 mV at 20 mA cm−2 with a low Tafel slope value of 39 mV dec−1.

量身定制的过渡金属掺杂磷化镍纳米颗粒,用于电化学氧释放反应(OER)†
外来过渡金属通过油胺,三辛基膦(TOP)和三辛基膦氧化物(TOPO)的稳定化,通过简单而又简单的自下而上的湿化学合成工艺掺入六角形磷化镍结构中:制备的过渡金属掺杂镍磷纳米粒子显示出高水平的掺杂,但不会对原始磷镍纳米粒子产生明显的晶体结构和形变畸变,而磷化镍纳米粒子在电化学氧释放反应(OER)中表现出出色的活性,在20 mA cm时的超电势小至330 mV -2 39毫伏癸低塔菲尔斜率值-1。
