| 英文摘要 | A novel TiO2-SrCO3 co-catalyst with a porous structure was fabricated by suspension plasma spraying. SrTiO3 as revealed by high-resolution TEM was formed by the chemical reaction of TiO2 with SrCO3 during the high-temperature plasma spraying. A narrow band gap (2.58 eV) and reduction in the recombination speed of photoinduced carriers of the coatings were detected by UV-visible diffuse reflectance spectrometry and fluorescence spectrometry, respectively. The enhanced visible light-driven photodegradation properties of the coatings resulted in promoted degradation of methylene blue. The composite coatings also demonstrated significantly pronounced bactericidal activities against the Gram-negative bacterium Escherichia coli than the pure TiO2 coatings, achieving a killing rate of over 99.7%. The results give insights on the potential to fabricate large-scale nano-TiO2-based porous photocatalytic coatings by suspension plasma spraying for versatile environmental applications.
