Improved photocatalytic performance via air‐plasma modification of titanium dioxide: Insights from experiments and simulations

Abstract: Commercial titanium dioxide is successfully plasma‐treated under ambient conditions for different periods, leading to reduced crystallite size and the creation of oxygen vacancies. Density functional theory‐based calculations reveal the emergence of additional localized states close to the conduction band, primarily associated with under‐coordinated titanium atoms in non‐stoichiometric titanium‐oxide systems. The plasma‐treated samples exhibit improved photocatalytic performance in the degradation of methylene blue compared to untreated samples. Moreover, the 4‐hour plasma‐treated photocatalyst demonstrates commendable stability and reusability. This work highlights the potential of cost‐effective plasma treatment as a simple modification technique to significantly enhance the photocatalytic capabilities of titanium‐oxide materials.
