Dr. Hamid Kazemi Hakki research focuses on advancing photocatalysis, surface engineering, and material design through the development of highly efficient TiO₂- and ZnO-based thin films, nanocomposites, and hybrid photocatalysts. Significant work has explored sol–gel dip-coated TiO₂–ZnO films, where investigations into surface properties, crystal structure, and film adherence have provided key insights into optimizing photocatalytic performance for pollutant degradation. Additional contributions examine the influence of thermal annealing on TiO₂ film morphology and crystallinity, demonstrating how controlled heat treatments enhance adhesion, surface uniformity, and photocatalytic activity. A major research direction includes the synthesis of Fe-ZnO photocatalysts supported on hydrophobic silica aerogels, enabling floating systems capable of highly efficient photodecomposition of BTX compounds in wastewater. These studies integrate sol–gel chemistry, sequential impregnation, and nanomaterial modification to achieve improved light absorption, charge separation, and catalytic durability. Across multiple projects, the research advances fundamental understanding of structure–function relationships while contributing practical solutions for environmental remediation, solar-driven oxidation processes, and sustainable catalytic technologies. This body of work supports ongoing innovation in photocatalytic materials with enhanced stability, reusability, and performance under real-world conditions.
