Candle flame fabrication of carbon coated CuO-Cu2O composite photocathode for photoelectrochemical water reduction

• C-CuO-Cu 2 O/CF hybrid was synthesized by a facile candle flame annealing. • The composition was confirmed by XRD, Raman and TEM techniques. • The C-CuO-Cu 2 O/CF electrode showed excellent photoelectrochemical activity. • High photoelectrochemical performance was due to carbon coating and hybrid composition. In this work, carbon coated-CuO-Cu 2 O composite on copper foam (C-CuO-Cu 2 O/CF) is synthesized by candle flame treatment and is...
