The advancement of industrialization and urbanization has led to various issues, including increased energy demand, excessive waste output, and negative environmental consequences. To mitigate the harmful effects of fossil-derived fuels, researchers are exploring the production and application of biofuels, which are produced from crops and emit lower pollution compared to fossil fuels. However, the high operational costs and limited production volume are major limitations in this process. Recent studies have investigated the use of nanocatalysts in biofuel production to overcome these challenges. This review discusses the application of nanocatalysts in different stages of biofuel production and their advantages and disadvantages.
Aggrandize industrialization and urbanization have resulted in many issues, such as increased energy demand, a plethora of waste output, and negative environmental consequences. As a result, there is excessive exploitation and over-usage of fuels and finite resources, which is paving the path for the exhaustion of fuels. Extensive use of these fossil-derived fuels has caused serious threats to the environment in terms of greenhouse gases emission leading to breathing troubles and other associated health hazards. In order to mitigate the harmful effects of fossil-derived fuels, researchers are more focused towards the production and application of bio-based fuels like bioethanol, biodiesel, biohydrogen etc. These biofuels are produced from crops and edible/non-edible materials and emit much lower pollution compared to fossil-derived fuels. Even though biofuels are effective alternatives, high operational costs with low production volume are the major limitations of this process, which the available technologies cannot handle. With increasing application of nanoparticles as catalysts in several sectors due to its unique properties such as high catalytic activity, surface to volume ratio, mechanical properties, etc., its application in biofuels production has been explored recently. The present review focuses on the application of nanocatalysts in various stages of biofuel production, different types of nanocatalyst used in the innovative era and for biofuels production and their merits and demerits. The supply of biofuels, such as feedstock is large, and with improved processing, we may be able to significantly lower our reliance on fossil fuels. The present review discusses the current updates, future possibilities, and challenges of biofuels production to help make the country self-reliant in the field of green energy.
