This work presents a successful example of the preparation of TiO2 and MoO3 NPs based hydrothermal method and the successful application of these NPs as active components, for the potential sulfur compound adsorbents, supporting environmental treatment. https://jns.kashanu.ac.ir/article_114015_afa5e2b8d1baf8c58c3c2b160c1f50fb.pdf
