Ultra-small β-Ni(OH)2 Quantum Dots Catalyst with Abundant Edges for Efficient Urea Oxidation Reaction The development of efficient nonprecious-metal catalysts for urea oxidation reaction (UOR) to improve the efficiency of electrocatalytic water splitting for hydrogen production remains a challenge. Herein, we synthesized an ultra-small β-Ni(OH)2 quantum dots catalyst with abundant edges (US-β-Ni(OH)2 QDs) by a coupling approach of co-precipitation and anionic exchange.

1. Introduction Recent years have witnessed rapid economic development in the coastal areas of China, with an increased population density and greater demand for fresh water, along with a severe shortage of water. Thus, seawater utilization is considered as critical to alleviating the shortage of freshwater resources in coastal areas.
