چکیده انگلیسی
Low cost and effective transition metal based catalysts are critical to the development of hydrogen generation techniques. In this paper, a multifunctional nanosized CoBO material has been developed that can act as highly active catalyst for both hydrolytic and electrolytic hydrogen production, affording a hydrogen generation rate of 7.45Â LÂ minâ1Â gâ1 for hydrolysis of sodium borohydride (NaBH4), and 10Â mAÂ cmâ2 water-splitting current at overpotentials of 270Â mV and 305Â mV for hydrogen and oxygen evolution reaction in 1.0Â M KOH. Meanwhile, oxygen doping is found to be critical to the activity of CoBO catalyst. This work will benefit the rational design of metal boride based material as highly active hydrolysis and electrolysis catalyst for hydrogen generation.
