ABSTRACT Microbial fuel cells and anaerobic digestion are promising bioenergy methods but inefficient and scalable. With its exceptional surface area-to-volume ratio, nano-catalysts are revolutionizing this field. Researchers have improved energy conversion efficiency by immobilizing or embedding nanoparticles on electrodes or catalytic supports to promote electron transport. Nanomaterials like graphene-based catalysts and metal nanoparticles speed up organic matter breakdown and make bioenergy systems more profitable. Researchers are working harder to find new bioenergy-generating methods to address environmental concerns and the demand for sustainable energy. The study discusses how nano-catalysts and enzymatic catalysts are revolutionizing bioenergy production in green energy. Additionally, enzymatic catalysts are the best bioenergy catalysts. Highly specialized, biocompatible, and renewable enzymes provide unrivaled biofuel production potential. Protein engineering and immobilization have improved enzymes for bioenergy systems. Enzymatic catalysts enable biofuel generation from more feedstocks without harsh chemical procedures by controlling biological reactions quickly and precisely. Combining nano-catalysts and enzymatic catalysts is promising. Nano-catalysts improve enzymatic processes by creating a favorable microenvironment, enhancing surface binding sites, and enabling substrate transport. This combination may maximize bioenergy systems’ biofuel output and wastewater treatment capabilities. In this study, as a green energy breakthrough a nano-catalysts was used for bioenergy generation. In the lab-scale experimental study from GOx which is an oxidoreductase that catalyses the oxidation of β-D-glucose to D-glucono-δ-lactone with glucose oxidase was coated with hematite/silicon dioxide magnetic nanocomposites (Fe2O3/SiO2 MNCs) and the effects of some experimental conditions on photocatalytic degradation process of enzymatic Gox was investigated. The physicochemical properties of the experimental samples were investigated by XRD, FTIR, FE-SEM, EDX, UV-vis spectra, HRTEM and VSM analyses, respectively. The maximum > 99% photocatalytic degradation yields for GOx were measured at 20 mg/l Fe2O3/SiO2 MNC and 1.0 mg/l GOx enzymatic nano-catalyst concentrations, at 300 W UV-vis light irradiation, after 120 min photodegradation time, at pH=7.0, and at 50oC, respectively. According to this study, it was found that by integrating the nano-catalysts to the enzymatic catalysts is a green energy breakthrough to detect sustainable energy generation. These advances will improve the bioenergy generation by overcoming current techniques, by opening new sustainable energy production prospects, and expediting our transition to a greener, more sustainable future. |
