Abstract:
Effective advancements for H 2 S removal are desperately expected to meet security and ecological necessities as natural guidelines on H 2 S emissions. Selective catalytic oxidation, as a green technology, has attracted attention owing to its direct conversion of H 2 S to S without thermodynamic constraints. Herein, we report a carbonencapsulated WO 3 (C@WO 3 -300) catalyst with nearly 100 % H 2 S conversion and 99 % S selectivity. Importantly, it likewise accomplishes noteworthy catalytic stability (over 120 h of continuous operation) and water resistance. Excellent durability may be attributed to the ideal porosity of C@WO 3 , which facilitates the adsorption and activation of H 2 S and O 2 . Additionally, the abundant lone pair electrons of carbon support can optimize the chemical environment of WO 3 -based catalysts and thereby benefit the O 2 activation. This study provides a new avenue for the rational design of efficient and durable catalysts for continuous catalytic oxidative desulfurization.
