Recently, the team from the Advanced Catalysis Center of Lanzhou University has made important progress in the photoelectric catalytic degradation of persistent water-phase organic pollutants.
The team adjusted the morphology of titanium dioxide (TiO2) photocatalysts on the nanometer scale to construct nano-tapered photocatalysts with efficient charge separation efficiency and mass transfer ability, which can reach more than 99% in the degradation of refractory organic pollutants such as phenolic compounds. Photoelectrocatalytic degradation efficiency.
According to reports, the environmental problem of organic pollution in the water phase is a serious threat to human life and health and is highly valued by countries all over the world. In particular, persistent organic pollutants in wastewater have high environmental toxicity and are difficult to degrade. Traditional biological or physical and chemical methods are difficult to effectively eliminate these pollutants. Therefore, Lanzhou University combines the advantages of photocatalysis and electrocatalysis, and the technology developed by Lanzhou University for the degradation of organic pollutants in the water phase by photoelectrocatalysis (PEC) is not only of great significance in scientific research, but also of important practical application significance.
