Green Synthesis of Semiconductors and Environmental Applications

Abstract

This chapter focuses on advancements in the green synthesis approach for nanomaterials and their environmental applications. The eco-friendly, cost-effective, and simple synthesis of inorganic nanoparticles on the environmental applications are discussed. The first section presents an introduction with the basic topics of the green materials synthesis. The second section summarizes the green chemical methods through different routes (precipitation synthesis, electrospinning synthesis, reflux condensation synthesis, hydrothermal, microwave-assisted hydrothermal methods) and the green routes using biological systems from biosynthetic process to synthesize nanoparticles and biosynthesis of passivating nanofilms using spontaneous formation. In the third section, the environmental and energy applications of nanomaterials, including solar cells, photocatalysis, and biohydrogen production are discussed. Therefore, the scientific community can experience the relation of the achieved nanomaterials with their plentiful application possibilities onto the environmental remediation.
