Rice husk valorisation by in situ grown MoS₂ nanoflowers: a dual-action catalyst for pollutant dye remediation and microbial decontamination.

ABSTRACT: Rice husk (RH) is a common agricultural waste generated during the rice milling process; however, a major portion is either burned or disposed of in landfills, posing significant environmental risks. In this study, RH waste was transformed into bio-based catalysts via delignification cum in situ growth of MoS₂ (DRH-MoS₂) for efficient pollutant dye removal and microbial decontamination. The developed DRH-MoS₂ exhibits nanoflower-like structures with a 2H-MoS₂ phase and a narrow band gap of 1.37 eV, which showed strong evidence of photocatalytic activity. With the presence of abundant hydroxyl functionality, delignified rice husk (DRH) exhibits a malachite green (MG) dye adsorption capacity of 88 mg g^-1. However, in sit
