A new type of photocatalyst is proposed on the basis of aero-β-Ga2O3, which is a material constructed from a network of interconnected tetrapods with arms in the form of microtubes with nanometric walls. The aero-Ga2O3 material is obtained by annealing of aero-GaN fabricated by epitaxial growth on ZnO microtetrapods. The hybrid structures composed of aero-Ga2O3 functionalized with Au or Pt nanodots were tested for the photocatalytic degradation of methylene blue dye under UV or visible light illumination. The functionalization of aero-Ga2O3 with noble metals results in the enhancement of the photocatalytic performances of bare material, reaching the performances inherent to ZnO while gaining the advantage of the increased chemical stability. The mechanisms of enhancement of the photocatalytic properties by activating aero-Ga2O3 with noble metals are discussed to elucidate their potential for environmental applications.

Adsorption Capability

In the present study, Pt, NiO, and RuO2 fine particles as co-catalyst were loaded on the LiInO2 surface by different methods for enhancing its adsorption capability and photocatalytic activity for methylene blue dye (MB) decomposition. Clear adsorption capability and marked photocatalytic activity for MB decomposition were confirmed on the co-catalyst loaded LiInO2 composite particles. Comparing with that of LiINO2, the previously reported NaInO2 photocatalyst had stronger adsorption capability and higher photocatalytic activity. However, the adsorption capabilities and the photocatalytic activities were separately in the same order of RuO2/AInO2 > Pt/AInO2 > AInO2 > NiO/AInO2 and Pt/LiInO2 > RuO2/LiInO2 > NiO/LiInO2 > LiInO2 for the two promising AInO2 (A = Li+ or Na+) photocatalyst.
