Deep Decarbonization and Desulfurization using CU-FE/VO- TIO2 in Ambient Temperature with Oxygen Vacancies

The presence of surface oxygen vacancies (Vo) has proven critical in enhancing the reaction and activation processes for the selective oxidation of hydrogen sulfide (H2S) and Carbon. However, achieving efficient H2S removal at ambient temperatures remains a significant challenge. In this study, we report the synthesis of a copper-iron impregnated titanium oxide (Cu-Fe/Vo-TiO2) catalyst designed to address this challenge through a facile impregnation method.

The objectives of this research were to synthesize and characterize novel multi-metal catalyst and evaluate the feasibility of its application to remove H2S in room temperature. 1) The synthesized novel multi-metal catalyst was characterized. 2) The effects of multi-metal catalyst, initial H2S concentration on the behavior of fixed-bed column, and reusability of novel catalyst was investigated. 3) A possible reaction mechanism of novel multi-metal catalyst was proposed through diverse chemical analysis.
