Photocatalytic water-splitting using TiO2
▶ Photocatalytic activities: reduction/oxidation reactions of photo-generated carries in photocatalysts
▶ Applications of photocatalysts: water splitting, disinfection of water and air purification
▶ Advantages of TiO2: non-corrosive, environmentally friendly, abundant and cost effective
▶ Challenges of TiO2: recombination of photo-generated electron/hole pairs and inability to utilize visible light

Heterojunction of bottom-open TiO2 nanotubes
▶ Photocatalytic activities: reduction/oxidation reactions of photo-generated carries in photocatalysts
▶ Applications of photocatalysts: water splitting, disinfection of water and air purification
▶ Advantages of TiO2: non-corrosive, environmentally friendly, abundant and cost effective
▶ Challenges of TiO2: recombination of photo-generated electron/hole pairs and inability to utilize visible light
▶ Fabrication of NiO adsorbed TiO2 nanotubes are achieved chemical bath deposition (CBD) method.
▶ CBD of NiO particles: Ni + OH → Ni(OH)2 → NiO + H2O
