Organic-Inorganic Hybrid Nanomaterials for Photoelectrochemical Water Splitting

Photoelectrochemical (PEC) water splitting employing nanoparticles is a practical, cost-efficient, and eco-friendly approach for hydrogen production. Organic–inorganic hybrids represent a novel class of adaptable functional materials with customized features and higher energy conversion efficiency. This chapter introduces hybrid nanomaterials that combine the best aspects of organic and inorganic elements, exploring their use in PEC water splitting and hydrogen production as clean and sustainable fuel sources. We highlight and examine two categories of hybrid materials: organic–inorganic composites and hybrid perovskites, reviewing their applications in constructing PEC cells. The discussion covers the designs and techniques used for synthesis, the structural properties, the impact of these hybrids on improving PEC performance, and the possible sustainable practices for their application for wastewater and seawater as electrolytes. This chapter also explores current developments, obstacles, and potential opportunities in the field, providing essential information for academics and professionals involved in sustainable energy research.
