Abstract

Chiral tartaric acid (TA)-modified Ni(OH)2 shows chiral-induced spin selectivity (CISS) effect, creating spin channels that significantly enhance electron transfer to promote the formation of NiOOH species. d-TA-Ni(OH)2 achieves a current density of 100 mA cm−2 at 1.38 V with a Tafel slope of 21.88 mV dec−1, highlighting its potential for the urea oxidation reaction.

手性酒石酸工程Ni(OH)2中的自旋极化电子转移解锁NiOOH对尿素电氧化的激活。
手性酒石酸(TA)修饰的Ni(OH)2表现出手性诱导自旋选择性(CISS)效应,形成的自旋通道显著增强电子转移,促进NiOOH物质的形成。D-TA-Ni(OH)2在1.38 V下的电流密度为100 mA cm-2, Tafel斜率为21.88 mV dec1,表明其具有尿素氧化反应的潜力。
