Photocatalytic activity for H2 evolution of TiO2 with tuned surface crystalline phase

Promotion effect of nickel loaded on CdS for photocatalytic H 2 production in lactic acid solution

“…Hydrogen has been considered a promising candidate because it is a new pollution-free and renewable energy. Since Fujishima and Honda found the photocatalytic phenomenon of hydrogen generation with TiO 2 in 1972 [1], TiO 2 has been extensively studied as a photocatalyst for hydrogen production [2][3][4][5]. However, TiO 2 is only sensitive to near UV light occupying merely 4% of the sunlight energy [6].…”

Optimised photocatalytic hydrogen production using core–shell AuPd promoters with controlled shell thickness

“…11 The pairs either recombine or react with surface adsorbed species; therefore an effective photocatalyst should be able to inhibit recombination whilst utilising the electronhole pairs to perform redox reactions efficiently. However, previous studies have shown that pristine TiO 2 based materials are poor photocatalyst materials for reforming reactions, 12 as the charge transfer from TiO 2 to surface adsorbed alcohols is significant slower than that of the recombination kinetics.…”

Efficient Degradation of Methylene Blue over Two‐Dimensional Au/TiO2 Nanosheet Films with Overlapped Light Harvesting Nanostructures

“…The latter makes TiO 2 without visible light ( > 400 nm) activity, resulting in a poor solar energy utilization. As a consequence, intense research activities have been devoted to the development of visible light active TiO 2 with high photocatalytic efficiency, such as surface photosensitization, element doping, semiconductor combination, and structural control [16][17][18][19][20][21][22][23][24][25][26][27][28].…”
