Abstract:

CdS/UiO-66-NH2 nanocomposite was solvothermally fabricated from cadmium acetate and the pre -synthesized UiO-66-NH2 in dimethyl sulfoxide (DMSO), which acted as the sulfur source. The as -obtained CdS/UiO-66-NH2 nanocomposite was immobilized on a glass fiber cloth (GF) and was applied for hydrogen sulfide (H2S) removal. The resultant GF immobilized CdS/UiO-66-NH2 nanocomposite exhibited a superior activity and high stability for H2S removal under visible light, in which UiO-66-NH2 acts as the main adsorbent and enriches H2S to promote CdS-based photocatalysis, while photocatalysis by CdS decomposes H2S adsorbed on UiO-66-NH2 to realize an in -situ regeneration of the adsorbent. The introduction of UiO-66-NH2 as the main adsorbent suppresses a fast deactivation of CdS due to an irreversible coordination between metal cation Cd2+ and H2S. This study not only developed a new type of material for fast and efficient removal of H2S, but also underscores the high potential of coupling physical adsorption and photocatalysis for the removal of volatile organic compounds (VOCs) and other gaseous pollutants in the environment.
