High photocatalytic hydrogen production from methanol aqueous solution using the photocatalysts CuS/TiO2

Preparation of ZnIn2S4/K2La2Ti3O10 composites and their photocatalytic H2 evolution from aqueous Na2S/Na2SO3 under visible light irradiation

“…The highly improved photocatalytic activity of ZnIn 2 S 4 /K 2 La 2 Ti 3 O 10 may be attributed to the following reasons: (1) efficient separation of electron-hole pairs. It is reported that CdS/TiO 2 composites showed higher photocatalytic activity than pure CdS because of the electrons transfer process from the conduction band of CdS to the conduction band of TiO 2 , which would be helpful for the separation of electron-hole pairs [17]. It is similar with ZnIn 2 S 4 /K 2 La 2 Ti 3 O 10 composites.…”

Synthesis of Nanocrystalline of Lanthanum Doped NaTaO3 and Photocatalytic Activity for Hydrogen Production

“…The study of photocatalytic water-splitting has focused on the development of various semiconductor materials, including: TiO 2 [10], ZnO/ZnS [11], and NaTaO 3 [12]. Among them, NaTaO 3 photocatalyst has the highest photocatalytic activity for hydrogen production [13].…”

Perspectives and Advances in Photocatalysis

“…Simamora et al (2013) found that CuO (2.5 wt%)-TiO 2 composite can photosplit water and generate 3.1 μmol H 2 h −1 in presence of 10 mgdm −3 methylene blue within 5 h, but 99 % of the methylene blue degrades in the process. However, exceedingly higher amount of hydrogen (about 570 mmol h −1 ) was produced by CuS/TiO 2 composite in presence of methanol, which corresponds to 32 times of the performance of P25-TiO 2 used under the same condition (Wang et al 2013). Noble metal compounds and the metal loaded photocatalysts have also shown high photocatalytic activity for hydrogen production including Ag 2 O(1 wt%)-loaded TiO 2 (H 2 production rate = 3,350 μmmol h −1 ) (Lalitha et al 2010), dye-sensitised or bare platinised TiO 2 (Kandiel et al 2011) and gold-loaded TiO 2 (Rayalu et al 2013).…”
