Titanium(IV) oxide  (Synonyms: Titanium dioxide)

Titanium(IV) oxide is a photosensitizer and photocatalyst. Titanium(IV) oxide can be used as a pharmaceutical excipient such as a flow aid, coating agent, sunscreen, colorant, etc. Pharmaceutical excipients or pharmaceutical excipients refer to other chemical substances used in the pharmaceutical process other than the drug ingredients. Pharmaceutical excipients generally refer to inactive ingredients in pharmaceutical preparations that can improve the stability, solubility and processability of pharmaceutical preparations. Pharmaceutical excipients also affect the absorption, distribution, metabolism and elimination (ADME) process of co-administered drugs. Titanium(IV) oxide can use light energy to generate electron-hole pairs to degrade pollutants. Photons excite electrons in TiO₂ to generate active oxygen species (such as ·OH and ·O₂^-), thereby oxidizing and mineralizing pollutants such as organic compounds and heavy metals. TiO₂ can be used in the research of environmental remediation fields such as water treatment, air purification and self-cleaning materials^[1][2][3].
