“…Cellulose is a linear macromolecular polysaccharide that is linked through β-1,4glycosidic bonds [31]. Under the high-temperature condition of 300 • C, cellulose decomposes and polymerizes to produce low-molecular-weight compounds, such as furfural, furan, glycolaldehyde, formic acid, H 2 O, and CO 2 [32]. In addition, anhydrous sugars are also formed during pyrolysis, such as levoglucosan, which is formed by the cleavage of glycosidic bonds and dehydration reactions [32].…”

In addition, anhydrous sugars are also formed during pyrolysis, such as levoglucosan, which is formed by the cleavage of glycosidic bonds and dehydration reactions [32]. If pyrolysis at a high temperature (>300 • C) is continued, levoglucosan will be further hydrated to generate levoglucosone, which will be converted to more stable oxygenated compounds such as furfural, 5-hydroxymethylfurfural, and pyran through the cyclization reaction [31,32].…”

These reactions are accompanied by the generation of functional groups, such as carboxylic acid (-COOH), ester (-COO-), ketone (-C=O), hydroxyl (-OH), and ether (C-O-C) groups [31].…”

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.
