About
Adrien P. Yepseu is a materials scientist whose research focuses on the development of visible-light-active photocatalytic thin films for environmental remediation. His work centers on the synthesis and characterization of composite metal oxide and sulfide semiconductors, particularly zinc oxide (ZnO) and copper sulfide (CuxS) systems. In his most cited work (2021, 6 citations), Yepseu pioneered the use of robotic spray pyrolysis deposition (SPD) to fabricate CuxS/ZnO composite thin films, demonstrating that this scalable, cost-effective technique yields materials with enhanced optical absorption in the visible spectrum. His key contribution lies in showing how the CuxS layer sensitizes ZnO to visible light, significantly improving photocatalytic degradation of organic pollutants under solar irradiation. This work addresses a critical limitation of wide-bandgap photocatalysts like ZnO, which are only active under UV light. Yepseu’s research has implications for developing practical, energy-efficient water purification technologies. His innovative use of robotic SPD for precise, reproducible thin-film deposition marks a notable methodological achievement in the field of photocatalytic materials engineering.
