Room-temperature hydrolysis cleavage of carbon disulfide over a palladium (II)-functionalized Polyarylether

Abstract

The development of low-energy catalysts is crucial for addressing the challenge of removing carbon disulfide contamination. This study presents a Pd(II)-anchored polyarylether where numerous nitrogen atoms coordinate with palladium nitrate. The catalyst demonstrated remarkable activity against carbon disulfide at room temperature. Furthermore, the integration of chemically stable polymers and sacrificial agents enhanced the catalyst's renewability. By synthesizing both experimental and theoretical results, we proposed a reaction pathway whereby hydroxyl nucleophiles attacked the C = S bonds, leading to the formation of carbon dioxide. This research offered significant insights into the pivotal role of immobilized palladium in the hydrolysis of carbon disulfide and underscored the potential of polymers in purifying water from contaminants.
