Cobalt Promotion in Rhenium Sulfide Catalysts
Created using ChatSlide
This research explores the design of catalysts for hydrodesulfurization (HDS) and hydrogen evolution reactions (HER), focusing on the limitations of supported rhenium sulfide catalysts and the enhancement provided by cobalt promotion. It employs operando X-ray absorption spectroscopy (XAS) and chemometric analysis to investigate Co–Re–S materials, examining sulfidation pathways and validating structures through DFT and spectroscopy. Key findings include the formation of ReS₂ and cobalt...
