Book Description
Heterostructured Photocatalysts for Solar Energy Conversion provides a comprehensive description of novel z-scheme hybrid materials based on metal oxide or chalcogenides-based semiconductor, or carbon-based nanomaterials (conducting polymers, graphene, and other carbon materials). The book explores energy conversion applications, such as hydrogen generation, water splitting, CO2 reduction or degradation of organic pollutants, and their associated new material and technology development. The book addresses a variety of topics, such as photochemical processes, materials and fabrication, degradation mechanisms, as well as challenges and strategies. The book includes in-depth discussions ranging from comprehensive understanding, to engineering of materials and applied devices. The concept of visible light active catalysis emerged in recent decades and continues to attract the scientific community. Driven primarily by an opportunity to develop novel multifunctional materials on one hand, and sustainable technologies on the other, several successful approaches have been explored. However, preparation, characterization, and application of visible light active Z-scheme heterojunction-based catalytic nanostructures are still at the foreground of research activity.

Book Description
Energy crises and global warming pose serious challenges to researchers in their attempt to develop a sustainable society for the future. Solar energy conversion is a remarkable, clean, and sustainable way to nullify the effects of fossil fuels. The findings of photocatalytic hydrogen production (PCHP) by Fujishima and Honda propose that “water will be the coal for the future”. Hydrogen is a carbon-free clean fuel with a high specific energy of combustion. Titanium oxide (TiO2), graphitic-carbon nitride (g-C3N4) and cadmium sulfide (CdS) are three pillars of water splitting photocatalysts owing to their superior electronic and optical properties. Tremendous research efforts have been made in recent years to fabricate visible or solar-light, active photocatalysts. The significant features of various oxide, sulfide, and carbon based photocatalysts for cost-effective hydrogen production are presented in this Special Issue. The insights of sacrificial agents on the hydrogen production efficiency of catalysts are also presented in this issue.
