For this reason, developing sustainable and economical fabrication methods for GQDs remains one of the most pressing and promising areas of research. In this context, lignocellulosic biomass (LCB) waste is a prime choice for the fabrication of GQDs due to the presence of high carbon and cellulose content as precursor and reducing agents. Additionally, LCBs are a prime source of potential bioenergy production, which is a key research hotspot nowadays to avoid environmental pollution, global warming, and energy crises. Therefore, the present review provides feasibility for sustainable and environmentally friendly fabrication of GQDs using LCB waste for cellulosic biofuels production technology improvement.
