Biofuel is one of the leading global alternatives to fossil fuels, particularly in the current scenario where energy sources are rapidly depleting. Petroleum fuels endanger both the climate and public health through releasing greenhouse gases during combustion. Nanoparticles acting as catalysts can improve selectivity, quality, and yield with current technology. Biofuel biomasses are abundant, and with improved processing, we may be able to reduce our reliance on fossil fuels significantly. The majority of techniqueshave recently been implemented, and many nanoparticles such as organic and inorganicmetals are now being appliedto improve biofuel fabrication. The largersurface area & volume ratio, design, reusability,catalytic activity, andstabilityof nanoparticlesmake them successful biofuel active ingredients. Furthermore, nanoparticles including nanosheets,carbon nanotubes, andcarbon nanofibershave been discovered to really be cost effective and durablecatalysts for immobilization ofenzyme, thereby enhancing biofuel fabrication in microbes. The incorporation of nanoparticles with in media to replenish thebiohydrogen (H2) fabricationis considered as a strong and potentialapproach. The possible impact of nanoparticlesin enhancing H2 production in darkand photo-fermentative microbes fed sugars as well as organic wastes substances was investigated in this review. Furthermore, the review provides a comprehensive overview of the use of various nanoparticles in biofuel fabrication, as well as significant challenges and potential future prospects.
