Synopsis

CaFe2O4 photocatalyst was successfully synthesized by nitrate route using La(NO3)3.6H2O, and Fe(NO3)3.9H2O as metal ion. The material was characterized by various techniques including TGA-DT, XRD, FT-IR, UV-visible, SEM-EDX, XPS and electrochemical analysis. The photocatalytic activity of the CaFe2O4 was successfully tested for hydrogen production H2 under visible light irradiation. A pure phase of CaFe2O4 is obtained at 850 C° with an orthorhombic structure and an average crystallite size of 31 nm. The photocatalytic activity reveals an optimal H2 production of 189 μmol within 30 min at 50°C in NaOH medium and a catalyst mass of 100 mg, under visible light irradiation.
