研究目的
To synthesize TiO2@rGO nanocomposites by an environmentally friendly and easy method and to demonstrate the factors that affect the photodegradation process using rhodamine-B (Rh-B) as the target organic pollutant.
研究成果
The synthesized TiO2@rGO nanocomposites showed enhanced photocatalytic and degradation activities for eliminating Rh-B dye under certain conditions. The addition of rGO oxide was found to be an efficient catalyst for improving the TiO2 photocatalytic performance. The prepared nanocomposites are promising for applications in environmental photocatalysis, especially in wastewater purification.
研究不足
The study focused on the photodegradation of Rh-B dye under specific conditions (pH, initial dye concentration, catalyst dose, and irradiation time). The applicability of the synthesized nanocomposites to other pollutants or under different environmental conditions was not explored.
