Hydrogen is among the most commonly discussed types of novel energies since it generates high energy in a green manner. Thus, hydrogen production under visible light has been studied with a novel hybrid catalyst including copper(II) phthalocyanine (CuPc) supported on graphene oxide (GO) and TiO2 in a pathway involving formic acid degradation. The homogenous distribution of CuPc on GO has been obtained through synthesis of CuPc in the presence of GO. CuPc@GO carried out the decomposition reaction of formic acid in the presence of TiO2 to afford H-2 with TOF of up to 79 h(-1) at room temperature. The catalyst indicated 103% and 39% enhancements in H-2 generation compared to CuPc/TiO2 and CuPc@GO, respectively.
