Probing the Possibilities: Advancing Photocatalyst Applications
Photocatalyst is a general term for semiconductor materials with photocatalytic function represented by nano-scale titanium dioxide. The representative photocatalyst material is titanium dioxide, which can produce strong oxidizing substances under light irradiation, and can be used to decompose organic compounds, some inorganic compounds, bacteria and viruses. Photocatalyst M aterials The commonly used photocatalyst semiconductor materials are titanium dioxide . ZrO 2 , ZnO, CdS, WO 3 , Fe 2 O 3 , PbS, SnO 2 , ZnS, SrTiO 3 , and SiO 2 are also photocatalyst materials. Since 2000, it has been found that some nano-noble metals (platinum, rhodium, palladium, etc .) have better photocatalytic properties. Research Findings of Photocatalyst s Photocatalyst materials based on zinc oxide have been discovered as early as the 1930s. In 1967, Akira Fujishima, a graduate student of the University of Tokyo working under the guidance of Associate Professor Keni...
