In a world where fossil fuels are running out, biofuels are one of the best green energy alternatives to fuels made from petroleum due to their environmentally beneficial qualities and low cost in comparison with non-renewable fossil fuels. Biofuels are produced from cheap and renewable sources and the energy stored in these biomasses can be assimilated to create sustainable electricity or heat, which can then be exploited to meet current and future societal needs in numerous situations. However, the production of biofuels on an industrial scale takes a lot of time because of the numerous constraints placed on currently available technology and the increased costs that go along with them. Moreover, the processes utilized to transform various feedstocks into the desired output also vary based on the materials and techniques employed. The supply of biofuel feedstocks is large, and with improved processing, we could significantly lower our reliance on fossil fuels. In this context, the use of nanoparticles (NPs) is a commendable solution to the present problems with biomass use, especially given their low cost. The unique qualities of nanomaterials, such as excellent catalytic properties, high surface area-to-volume ratio, remarkable selectivity, and reusability make them admirable tools for boosting biofuel generation. This review predominantly focuses on the contributions of nanotechnology and various immobilization methodologies in accelerating biofuel production from biomasses that might fill in the research gap, which was previously limited by the relatively lower efficiency of traditional techniques of biofuel generation.

Summary At present, the energy requirements of the world majorly depend on fossil fuels, but overconsumption leads to a serious energy crisis, and the greenhouse gases released during the burning of fossil fuel arouse various environmental issues like global warming, acid rain, etc. Biohydrogen is one of the promising fuel among the alternative sources of energy, because it can be derived from renewable sources, cost effective, high energy content, clean, and environmentally friendly fuel. Biohydrogen has been produced by various methods namely thermo‐chemical gasification, solar gasification, electrolysis of water, pyrolysis, steam reforming, and biofermentation. Among them, the biological way of hydrogen production is an environmentally friendly method and does not require any external energy, but beside hydrogen dark fermentation could also generate CO2 and other gases as by‐products, which could contribute to the greenhouse gas augmentation if not well‐controlled. But the quantity of hydrogen production through the photo and dark fermentation method is low, which is also a major constrain for commercialization. In order to overcome this obstacle, many researchers engaged them in the biohydrogen production with nanotechnology which is a potential technique for efficient biohydrogen production. Hence, this review is mainly focused to providing an update of nanotechnology in biohydrogen production and state‐of‐the‐art on its emerging field. In this regard, this review paper highlighted several new findings and achievements in biohydrogen production using both inorganic and organic nanoparticles. Additionally, the synthesis of sustainable and environmentally friendly green nanoparticles in biohydrogen production has been addressed.

Biohydrogen is considered a green fuel due to its eco‐friendly nature since it only produces water and energy on combustion. However, their lower yield and production rate is one of the foremost challenges that need an instant sustainable approach. The use of nanotechnology is a potential approach for the enhanced generation of biohydrogen, owing to the significant characteristics of the nanomaterials such as greater specificity, high surface‐area‐to‐volume ratio, better reactivity and dispersibility, enhanced catalytic activity, superb selectivity, greater electron transfer, and better anaerobic microbiota activity. This article explores the recent trends and innovations in the production of biohydrogen from wastewater through the applications of different nanomaterials. The potential of various nanomaterials employed for biohydrogen production from wastewater is evaluated and the impacts of important parameters such as the concentration and size of the nanomaterials, temperature, and pH on the production and yield of biohydrogen are explained in detail. Several pathways involved in the mechanistic approach of biohydrogen generation from wastewater are critically assessed. Lastly, numerous technological challenges are highlighted and recommendations regarding future research are also provided.
