Utilization of nano materials in hydrogen production - Emerging technologies and its advancements: An overview

Abstract

Novel, environmentally friendly, and clean energy sources have been developed in response to increased global energy demand and the associated effects of global warming produced by greenhouse gas emissions from fossil fuels. As a result, the development of renewable and clean energy depends largely on hydrogen as a key component. Even, nanomaterial procured from waste for Hydrogen synthesis can be processed through several biochemical/thermochemical procedures. Variables comprising feedstock characteristics, operation needs and technology availability were examined to support technology choice and system features. Such amendments proceed with costly synthesis and operation strategies, low operating efficiencies, insufficient management along with logistics, as well as lack of operation policies. Perhaps, nanotechnology is now crucial in the creation of nanomaterials for the production of hydrogen as a pertinent origin through renewable energy causatives. Nanomaterials have received a great deal of interest in recent years owing to their unusual mechanical, electrical, electronic, optical, and magnetic properties on their surfaces. These features had a predominant impact on the evolution of production and storage techniques, as well as the difficulties experienced in bringing the product to market. This article provides an overview of the nanomaterials that contributed to hydrogen synthesis, storage, and usage. This article will cover a wide range of issues, including Nanomaterials for Photocatalytic (PC) reactions, anaerobic digestion, hydrothermal gasification, microbial fuel cells, lifespan evaluation, and future research studies.
