Outline of Final Research Achievements

Here, we report simple and effective synthesis route of transforming weak reactive anatase TiO2 catalytic crystals into highly energetic, light active TiO2 by solution plasma processing (SPP). As a result, SPP treated (3 hr) TiO2 exhibit high photocatalytic performance in acetaldehyde deformation compare to pristine TiO2 tested under identical condition. Synthesis of highly reactive core-shell structured TiO2 with oxygen vacancies at room temperature compare to conventional high temperature solid-state process demonstrating SPP is a powerful approach for designing broad range of solar-light driven photocatalytic materials.
