This review focuses on wastewater treatment methods based on catalytic technology, with an emphasis on developing greener, more efficient, and economically favorable catalysts using agricultural residues. The main discussions include the preparation of biochar, improving catalytic performance, interactions between biochar surface properties and pollutants, and designing biochar-based catalysts for efficient pollutant degradation. The aim is to provide a waste disposal alternative for environmental pollution alleviation and the promotion of green chemistry and sustainable development.
Wastewater treatment methods based on catalytic technology are receiving more and more attention in recent years. In order to achieve the high-value utilization of agricultural residues, the development of greener, more efficient, and economically favorable catalysts is the focus of this review. The main contents include: (i) discussions around the differences in surface morphology, chemical stability, electrical conductivity, porosity, and the specific surface area of the prepared biochar according to the biochemical composition of different agricultural residues; (ii) through the above comparison, the shortlisting and selection of suitable catalysts for the preparation of agricultural residues to improve the adsorption and catalytic performance; (iii) discussions around the interaction mode and catalytic mechanism between the surface properties of biochar and pollutants; (iv) based upon future needs, discussions around making full use of the distribution of the pyrolysis products of agricultural residue, and designing biochar-based catalysts to achieve the efficient degradation of pollutants in wastewater. The review aims to provide a waste disposal alternative for the alleviation of environmental pollution and the promotion of green chemistry as well as sustainable development.
