Cu2O nanoparticles supported on pristine carbon nanotubes were synthesized by a green electroless plating method using glucose as the reducing agent. The Cu2O/CNTs nanocomposite materials exhibited remarkable electrocatalytic activity towards hydrogen evolution reaction in alkaline solution, making them efficient HER electrocatalysts for water splitting.
Cuprous oxide (Cu2O) nanoparticles supported on pristine carbon nanotubes (Cu2O/CNTs) were synthesized by a facile and green electroless plating method, in which glucose replaced formaldehyde as the reducing agent. The as-prepared Cu2O/CNTs nanocomposite materials as electrocatalysts exhibited remarkable electrocatalytic activity towards hydrogen evolution reaction in alkaline solution, with an overpotential of 101 mV at -10 mA cm(-2) and a Tafel slope of 88 mV dec(-1). In addition, Cu2O/CNTs electrocatalysts maintained high electrocatalytic activity after the accelerated durability tests in 0.1 M KOH. All these results indicated Cu2O/CNTs can be utilized as efficient HER electrocatalysts for water splitting.
