Abstract

The growing demand for sustainable energy and concerns regarding fossil fuel depletion have accelerated research into bioenergy production technologies. However, conventional bioenergy processes often suffer from low conversion efficiencies, high energy requirements, and limited catalyst performance. Nanotechnology has emerged as a promising approach to overcome these challenges through the application of nanomaterials and nanocatalysts with high surface area, enhanced catalytic activity, and superior electron transfer properties. Nanocatalysts improve biodiesel production by increasing transesterification efficiency and facilitating catalyst recovery. In bioethanol production, nanomaterials enhance biomass pretreatment, enzyme immobilization, and fermentation processes. Nanostructured materials also improve microbial fuel cell performance by promoting electron transfer and increasing power generation. Furthermore, nanotechnology enhances biomass conversion technologies such as pyrolysis, gasification, and hydrothermal liquefaction, leading to higher fuel yields and improved product quality. This review discusses the historical development, applications, advantages, challenges, and future prospects of nanomaterials in bioenergy production, highlighting their potential for sustainable and efficient renewable energy generation.
