Current Progress and Difficulties in the Application of Nanomaterials for Biodiesel Production
摘要
The sustainability of the energy supply is crucial for achieving sustainable socio-economic development, taking into account economic, environmental, and public health considerations. Despite the scarcity of fossil fuel resources, a significant rise in energy consumption has occurred over the previous century. Because of the problems associated with global warming brought on by rising greenhouse gas concentrations in the atmosphere and the finite supply of fossil fuels, it is crucial to decrease our significant reliance on fossil fuels. These factors compelled nations worldwide to seek out other fuel options. Biodiesels offer public health benefits, but their environmental and economic viability may be called into question because to the controversies surrounding their feedstocks, such as land use change and the conflict between fuel and food production. Hence, it is crucial to exert additional endeavour in mitigating the drawbacks of biodiesel production by the utilization of new technologies, such as nanotechnology. Because of their energy reaction efficiency, selectivity, and time management qualities, nanoparticles (NPs) present a very practical answer to the current problems associated with the use of biomass. They also save expenses. Recently, many strategies have been implemented to boost biofuel production, with the utilization of several types of nanoparticles including metal, magnetic, and metal oxide. The distinctive characteristics of NPs, including their structure, durability, lower ratio of volume to surface area, catalytic capability, and capacity to be reused, contribute to their effectiveness as biofuel additives. Furthermore, nanomaterials like carbon nanofibres, nanotubes as well as nanosheets have demonstrated cost-effectiveness and stability as catalysts for immobilizing enzymes, hence enhancing the synthesis of biofuels. Although nanotechnology offers advantageous characteristics for biodiesel generation, the inclusion of nanoparticles in biological systems also presents significant health and environmental concerns.
