Biochar-Driven Activity Enhancement of Co3O4 Catalyst for 4-Nitrophenol Reduction: RSM-CCD Optimization, Kinetic Insights, and Recyclability
To decrease the environmental and health consequences associated with pollution, several cobalt oxides-decorated biochar substrates have been developed for effective catalytic reduction of 4-NP. The porous biochar was produced by pyrolysis of sewage sludge and acid demineralization, and subsequently, Co3O4 was loaded w...
