In this study, the use of solar energy for the conversion of CO2 to energy bearing materials by ZnS and CuS photocatalysts was investigated. ZnS, CuS, Montmorillonite (MMT), and cetyltrimethylammonium bromide nanocomposites were synthesized by a simple solution method and were studied by FTIR, TEM, SEM, and XRD to examine the dispersion, size, and crystal structure of the produced nanocatalysts and the Montmorillonite base. The results of photocatalytic reduction revealed that the highest yield is related to the 10% CuS doped sample, which consequently shows that it has much more positive effects than acid activation on the overall yield of methane production.
