Description
Summary:In a globalized world, energy remains a critical driver of development. The reliance on non-renewable fossil fuels has led to pollution, health concerns, and accelerated climate change due to greenhouse gas emissions. As fossil fuel reserves diminish, biofuels derived from biomass present a promising and sustainable alternative. Biomass, being abundant and renewable, has the potential to replace fossil fuels, with advances in technology and a focus on green synthesis enabling more efficient and environmentally friendly production processes. Heterogeneous catalysts play a crucial role in biofuel production, significantly impacting the development of more sustainable energy solutions. These catalysts, which operate in a different phase from the reactants, are crucial for achieving high conversion efficiency, recyclability, and minimal environmental impact in biofuel production. Specifically designed to break down lignocellulosic biomass, these catalysts are essential for a carbon-neutral biofuel production process and for driving sustainable development. This article explores the historical development and evolving role of these catalysts in biofuel technology along with a categorization of various catalysts used in biofuel production. The discussion includes an examination of biomass sources and its structural and chemical compositions vital for conversion processes. The application of heterogeneous catalysts in producing diverse biofuels—such as bioethanol, biobutanol, biogas, biodiesel and biohydrogen are analyzed, highlighting recent advancements and improvements in efficiency. Insights and recommendations for future research underscore the indispensable role of heterogeneous catalysts in advancing sustainable energy practices and securing our energy future.
