Customized High-Value Agricultural Residue Conversion: Applications in Wastewater Treatment

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.
