Description Nano structured metal oxides including TiO2, Co3O4 and Fe3O4 have been synthesized and
evaluated for their photocatalytic activity for hydrogen generation. The photocatalytic
activity of nano cobalt oxide was then compared with two other nano structured metal
oxides namely TiO2 and Fe3O4. The synthesized nano cobalt oxide was characterized
thoroughly with respect to EDX and TEM. The yield of hydrogen was observed to be 900,
2000 and 8275 mmol h�1 g�1 of photocatalyst for TiO2, Co3O4 and Fe3O4 respectively under
visible light. It was observed that the hydrogen yield in case of nano cobalt oxide was more
than twice to that of TiO2 and the hydrogen yield of nano Fe3O4 was nearly four times as
compared to nano Co3O4. The influence of various operating parameters in hydrogen
generation by nano cobalt oxide was then studied in detail.
