The nanorod-like α-Bi2O3 have been synthesized from the microrod-like α-Bi2O3 using g-C3N4 as a template. The photocatalytic activity of α-Bi2O3 is highly improved by nearly 800% in the oxidation of the gaseous IPA (isopropyl alcohol). The formation mechanism of the nanorod-like α-Bi2O3 was further studied, and demonstrated to be the CO2 corrosion effects.
