Preparation of Nanowire like WSe(2)-Graphene Nanocomposite for Photocatalytic Reduction of CO(2) into CH(3)OH with the Presence of Sacrificial Agents

A nanowire-like WSe(2)-graphene catalyst was prepared via ultra-sonication and was tested in terms of the photocatalytic reduction of CO(2) into CH(3)OH under irradiation with UV/visible light. The prepared nano-composite was further characterized via XRD, SEM, TEM, Raman and XPS. The photocurrent a...

description A nanowire-like WSe(2)-graphene catalyst was prepared via ultra-sonication and was tested in terms of the photocatalytic reduction of CO(2) into CH(3)OH under irradiation with UV/visible light. The prepared nano-composite was further characterized via XRD, SEM, TEM, Raman and XPS. The photocurrent analysis was further tested for its photocatalytic reduction of CO(2) using gas chromatography (GCMS-QP2010 SE). To further improve the the photo-catalytic efficiency, a sacrificial agent (Na(2)S/Na(2)SO(3)) was added to the WSe(2)-graphene nanocomposite and was found to improve the photo-catalytic efficiency, with the methanol yield reaching 5.0278 µmol g(−1)h(−1). Our present work provides a convenient way to prepare nanomaterials various morphologies that have future applications for environmental remediation.
