Germanium-assisted growth of titanium dioxide nanowires for enhanced photocatalytic and electron emission performance

Ag Nanoparticle-Decorated Cu2S Nanosheets for Surface Enhanced Raman Spectroscopy Detection and Photocatalytic Applications

“…Interestingly, the photocatalytic activity of the Ag/Cu 2 S nanosheets surpassed that of the Cu 2 S nanowires in our previous work [8]. Figure 3d shows that the photocatalytic degradation of the RhB dye followed a pseudo-first-order reaction according to the Langmuir-Hinshelwood mechanism [30,31], applying Equation (1):…”

Effect of Nitrogen Doping on the Photocatalytic Properties of TiO2

“…[7][8][9][10][11][12] However, there are still problems in the current photocatalytic application process, such as the wide band gap energy can only be excited by ultraviolet light, and the photo-generated electron-hole recombination easily affects the photocatalytic efficiency. [13][14][15][16][17][18] As demonstrated in the literatures, N doping can effectively reduce the bandgap energy (Eg) [19][20][21] and promote the separation of electron-hole pairs. [22][23][24] Studies have fully demonstrated that the hybridization of the 2p orbital of N and the 2p orbital of O after N doping increases the valence band of TiO 2 , thereby reducing the Eg of TiO 2 and broadening the response range of TiO 2 to visible light.…”
