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 Bi₂WO₆/MoSe₂/Bi₁₂O₁₇Cl_xBr_2−x (2%) showed highest photocatalytic efficiency. In the presence of visible light, it degraded 99.76% MB in 60 min and produced 490.56 h⁻¹ g⁻¹ 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.

能源危机和水污染是对现代生活的两个严重威胁。为了克服这些问题，使用简单的水热方法开发了三元光催化剂以产生氢能和降解MB。合成的三元光催化剂对产生氢能和降解亚甲基蓝表现出增强的光催化效率。使用SEM，XRD，UV，PL和BET分析合成的光催化剂。在所有制备的光催化剂中，复合物Bi ₂ WO ₆ / MoSe ₂ / Bi ₁₂ O ₁₇ Cl _x Br _2-x（2％）表现出最高的光催化效率。在可见光的存在下，它在60分钟内降解了99.76％MB，并产生了490.56 h ^-1  g ^-1氢能。效率的提高归因于结晶度的增加，高吸收区，更大的表面积以及复合物之间的协同作用。相信这项研究工作将为合成光催化剂提供实用的途径，以在实际应用中改善氢能和水污染的降解。
