Efficient photo-catalytic desulfurization of real diesel fuel using tungsten oxide decorated porous purslane-derived biochar for clean energy generation and environmental remediation

A critical stage in the production of diesel fuels is the extreme reduction of sulfur compounds, which helps shield the environment from harmful emissions. It is also economically advantageous to use a process that is cost-effective for this type of work. In keeping with these ideas, this work presents the photocatalytic method of producing low-sulfur diesel fuel while being exposed to visible light. During this research plan, a fabricated structure consisting of tungsten oxide and porous purslane-derived biochar is presented as a new photocatalyst. Using H2O2 as an oxidant could result in notable improvements in the desulphurization degrees by the 10wt% WO3/Biochar photocatalyst. Through the use of X-ray diffraction, FT-IR, BET, EDX, and scanning electron microscopy, the physical properties of the prepared catalyst were studied, and photoluminescence was used to assess its photo properties. To achieve 97.19% desulfurization efficiency, the reaction time, oxidant amount, and catalyst dose were investigated. The desulfurization efficiency can reach 97.05% after five cycles.
