Recent progress in Biomass-derived nanoelectrocatalysts for the sustainable energy development

The changing global approach for protecting the planet and turning to a low-carbon economy has made the growing demand for biomasses at the core of biochemistry. Biomass contains all the substances in nature that in the recent past were living things, made from living organisms or their wastes. Biomass is carbon-based and is a mixture of organic molecules, including hydrogen, usually oxygen, and often nitrogen, and small amounts of other atoms such as alkali metals, alkaline earth metals, and heavy metals. Production and consumption of biomasses grew in sustainable procedures do not cause a net change in the CO2 content of the atmosphere. So, the biomasses can be regarded as carbon neutral due to the mentioned net carbon cycle they involve. Energy production from biomass sources is utilized to generate electricity and heat. These sources are renewable sources and CO2 production of these sources is natural and does not produce greenhouse gases. The development of practical techniques for sustainable energy generation from biomass is one of novel strategy to overcome air pollution and move towards the sustainable bioeconomy. This study reviews recent progress in Biomass-derived nanoelectrocatalysts for the sustainable energy development that includes biomass-based electrocatalyst synthesis, biomass-based nanoelectrocatalysts for water splitting, and biomass-based nanoelectrocatalysts for fuel cells. Finally provides future perspectives to motivate future research such as the necessity to increase agricultural and so food production while reducing inputs to balance biomass valorization for energy production versus biomass upgrading, and to develop practical techniques for cheap pretreatment and metabolic engineering of lignocellulosic and efficient strategies for the commercial-scale production of lignocellulosic based-biofuels.

Automated summary

The changing global approach for protecting the planet and turning to a low-carbon economy has increased the demand for biomasses. Biomass is a renewable carbon-neutral compound that can be used for electricity generation and heating. Developing practical techniques for sustainable energy production is a novel strategy to address air pollution and promote a sustainable bioeconomy.
