Cobalt doped MoS2: A photoactivated nanomaterial for removal of methylene blue and phenol

Abstract

This research work reports the study about synthesis, characterizations and Photocatalytic applications of hydrothermally produced MoS₂ and Cobalt doped MoS₂ nanomaterials to overcome the environmental pollution caused by wastewater. MB dye and Phenol were used as model pollutants for evaluation of photocatalytic proficiency of MoS₂ and Cobalt doped MoS₂ nanostructures. The well matched ionic radius of Cobalt with host Mo atom increases their probability regarding alteration of nanomaterial’s optical, structural and catalytic properties. The Cobalt incorporation provided the synergistic effect attributed to efficient degradation up to 96 % and 80 % for MB dye and phenol respectively. Additionally, the prepared samples were characterized to elucidate their optical, electronic and structural properties. Scavenger analysis and reusability test had performed to check the role of active species and stability of optimized sample. This study predicts that the fabrication of Cobalt doped MoS₂ can be used as potential and promising photocatalyst for industrial applications for wastewater treatment.
