Nanomaterials Synthesis and Characterization for Photocatalytic Applications

Advances in nanomaterials for photocatalysis centre on tailoring crystal structure, surface chemistry and morphology to optimise light absorption and charge separation. Synthetic approaches span sol–gel and hydrothermal routes, microwave-assisted and plasma-driven processes, and notably solution combustion synthesis (SCS), each offering distinct control over particle size, defect density and porosity. Characterization utilises X-ray diffraction, electron microscopy, surface-area analysis and spectroscopic methods to correlate structural features with photoaktivation efficiency. Such engineered photocatalysts enable applications in water treatment, solar fuel production and emission abatement, addressing global challenges in sustainable energy and environmental remediation. Interdisciplinary efforts now integrate life-cycle thinking, recyclability and scale-up strategies to bridge laboratory breakthroughs and real-world deployment.
