Abstract: Biogas is quickly becoming a viable renewable energy option since they produce less pollution than traditional fuels and are cheaper than conventional fuels. However, research and resources are turning towards the use of technologies that will optimise their yields in order to speed up their development. Due to their unique characteristics, nanoparticles are attracting more and more attention from scientists in a variety of disciplines, including electronics, agricultural, pharmaceutical, and food industries. The studies on biogas are looking at them as a way to boost the efficiency of similar bioprocesses. A close look at the research done on nanoparticles and their potential use in improving the yields of biogas processes including biogas, biohydrogen, bioethanol, and biodiesel synthesis has been undertaken in this review. In addition, it describes several nanomaterials (including metals, nanotubes, and nanofibers) that have been implemented in these bioprocesses. Also, the assessment on how the immobilized nanoparticles affect biogas production and how well they can block inhibitory chemicals in controlled experiments were elaborated. The impact that nanoparticles have on the efficiency of biofuels manufacturing processes is briefly discussed. In the end, the review suggests ways in which the nanoparticle-based bioprocesses might be enhanced, as well as suggested avenues for further study.
