Molybdenum disulfide (MoS₂) is a promising material for energy and environmental applications. In this paper, we report the direct hydrothermal growth of MoS₂ on a Mo support and its application in the rarely explored electrochemical CO₂ reduction (EC CO₂R) process. To investigate the effects of metal overlayers and the MoS₂ support, Au, Ag, and Cu were sputter-deposited on a MoS₂ electrode. Large amounts of CH₄, C<SUB>2−3</SUB> hydrocarbons, and formate were produced via EC CO₂R on bare MoS₂. The introduction of a Au overlayer on MoS₂ enhanced the production of CO, methanol, and formate. Furthermore, the alkanes (C𝑛H<SUB>2𝑛+2</SUB>, 𝑛 = 2, 3) to alkenes (C𝑛H<SUB>2</SUB>, 𝑛 = 2, 3) ratio was dependent on the applied potential and overlayer metals. Notably, photoirradiation remarkably increased the CO and C₂H₄ concentrations by 28-fold and 10-fold, respectively. These findings provide valuable insights for the development of MoS₂-based materials for CO₂ recycling.
