← ScienceWhich consequence results when titanium dioxide promotes reactions?
A)Hydrogen peroxide concentration increases extensively.✓
B)Methanol production declines significantly afterward.
C)Material strength rapidly reduces at interfaces.
D)Ultraviolet light absorption rates decrease sharply.
💡 Explanation
Electron-hole separation occurs due to band gap excitation, enabling redox reactions. This leads to oxidation of water molecules, causing excessive buildup of hydrogen peroxide, because oxidation reactions dominate, therefore excessive peroxide forms, rather than reduced reaction products.
