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.
