“…In addition, it can be found from Tables and that different agricultural biomass residues show a broad range of productivity toward the formation of furfural or HMF. Several reasons may be attributed to this phenomenon. ,− (1) Different biomasses possess different hemicellulose and cellulose structures due to the nature of plant. (2) The contents of hemicellulose and cellulose are varied in different biomasses, making the sources for formation of furfural and HMF vary.…”

Catalytic transformation of agricultural residues to furfural is a potential source of income for those who have biomass residues to be disposed because furfural derivatives are platform molecules for the preparation of various chemicals, additives, and pharmaceutical precursors. In this work, a modified KIT-6 molecular sieve catalyst with dual acid sites of Lewis acid and Brønsted acid is prepared by grafting sulfonic acid groups on Sn 4+ -doped KIT-6. Characterizations are applied to reveal the generation of Lewis acid and Brønsted acid by the doped Sn 4+ and grafted sulfonic acid groups. The dual acid on the catalyst synergistically contributes to the satisfying catalytic transformation of xylose to furfural. In addition, the one-step and two-step transformations of agricultural residues to furfural and 5-hydroxymethylfurfural were studied. The prepared catalyst shows satisfying stability, and the reason for the slight decline of the catalytic performance was revealed.

“…The CC comprises 500–1400 D‐glucose units that form microfibrils, which are, in turn, arranged together to form cellulose fibrils. The formed cellulose fibrils are then deposited within the amorphous and crystalline regions of the cell wall, finally forming a lignocellulosic complex 62,63 . The complex cross‐linkages within the lignocellulosic biomass contribute to its recalcitrance.…”

The emission of greenhouse gases, particularly carbon dioxide, predominantly from fossil fuel combustion has received critical warnings several times as their levels exceed the tolerable limits in view of global warming. This calls for a paradigm shift from a fossil fuel‐based source to a less hazardous bioenergy source. Plant feedstock is an attractive source of raw materials for bioenergy production; however, chemical or enzymatic digestion of the feedstock is expensive owing to the supramolecular lignocellulosic barrier, indicating the need for better alternatives. Several attempts have been made towards reducing the biomass recalcitrance of straw using genetic transformations. We present a review highlighting potential plant candidates for bioenergy production, the lignocellulose composition of the feedstock, how the composition can impede enzymatic degradation, the regulation of lignocellulose polymer biosynthesis, and the influence of genetic transformation on biomass saccharification. Moreover, the review also discusses conflicting research interests in biomass recalcitrance and suggests a common ground. The review findings suggest that bioenergy production from crop straws will drastically reduce over‐dependence on fossil fuels and consequently pollution levels.
