Abstract
Energy crisis and water pollution are two serious threats to modern life. To overcome these issues, a ternary photocatalysts is developed using simple hydrothermal method for the production of hydrogen energy and degradation of MB. The synthesized ternary photocatalysts exhibited enhanced photocatalytic efficiency for the production of hydrogen energy and degradation of methylene blue. The synthesized photocatalysts were analyzed using SEM, XRD, UV, PL and BET. Among all the prepared photocatalyst the composite Bi

hydrogen energy. The enhancement in the efficiency was due to the increase in the crystallinity, high absorption region, larger surface area and synergetic effect between the composite. It is believed that this research work will give a practical route to synthesize photocatalyst for improved hydrogen energy and water pollution degradation in practical applications.
