Core-shell Ag@Ni cocatalyst on the TiO2 photocatalyst: One-step photoinduced deposition and its improved H2-evolution activity

Triethanolamine-mediated photodeposition formation of amorphous Ni-P alloy for improved H2-evolution activity of g-C3N4

“…Actually, the above result is reasonable because the work function of the g-C 3 N 4 (5.32 eV) is higher compared with the value of Ni-P (4.94 eV), which can induce the free-electron transfer from the Ni-P alloy cocatalyst to g-C 3 N 4 until their Fermi levels are identical (Fig. 7c) [66][67][68]. Herein, the above electron transfer between the Ni-P alloy and g-C 3 N 4 can create an internal electric field pointing from the Ni-P alloy to g-C 3 N 4 , which can greatly induce the orientation shift of photo-induced electrons from the conduction band (CB) of g-C 3 N 4 to the Ni-P alloy cocatalyst (Fig.…”

Effects of Ag0-modification and Fe3+-doping on the structural, optical and photocatalytic properties of TiO2

“…Due to the surface plasmon resonance (SPR) effect of Ag particles deposited on TiO 2 surface, the absorption of visible light can be enhanced, reducing the E g . 15,16,34,36,37 On the other hand, the substitutions of Ti 4+ ions with Fe 3+ ions form impurity energy levels between the conduction band and valence band in the forbidden band, thereby decreasing the E g . 5,7,10,21,33,43,51 Therefore, the change of E g is not the main reason for the decreased photocatalytic performance of Fe-TiO 2 and 1% Ag/1% Fe-TiO 2 .…”

Construction of ZnTiO3/Bi4NbO8Cl heterojunction with enhanced photocatalytic performance

“…Photocatalysis has been attracting great interests in recent years, which already been applied in the fields of solar cells, water splitting, and water purification [1][2][3][4]. It has been reported that oxide based semiconductors are active photocatalysts [5], typified by TiO 2 [6,7], ZnO [8], and so on. However, individual pristine ZnO or TiO 2 does not show gratifying photocatalytic performance.…”
