Nano-heterojunctions as Functional Interfaces for Clean Energy Generation: An Overview

Assistant Professor, Department of Chemistry, Cachar College, Silchar, 788001, Assam, India

The chase for clean, renewable and sustainable alternate source of energy is on the rise due to rapid annihilation of exhaustible energy sources and increasing environmental concerns. Hydrogen, as clean fuel, has a great potential to meet the future energy demands. Photocatalytic splitting of water to produce clean hydrogen fuel may be one of the best options as it utilizes earth abundant water and inexhaustible sunlight. However, development cost effective and efficient photoelectrocatalysts which can convert visible light energy to produce clean hydrogen fuel from water is a prerequisite to enable hydrogen as an alternate fuel as visible light contributes the major fraction of the sunlight. Moreover, the physicochemical modifications like morphology, introduction of oxygen vacancies, high energy facets and heterojunction structures etc. may have significant effect on the photocatalytic activity of the nanocatalysts. This chapter aims to explore recent advancements in the design of nanoheterojunction photocatalysts with enhanced visible light responsiveness, and to highlight how structural modifications, facet engineering, and oxygen vacancies contribute to efficient water splitting for sustainable hydrogen production.
