Hydrogen production over metal-loaded mesoporous-assembled SrTiO3 nanocrystal photocatalysts: Effects of metal type and loading

Electronic structure and photocatalytic properties of Ag–La codoped CaTiO3

“…On the other hand, the doping of foreign elements into active photocatalysts with wide band gaps in order to make a donor or an acceptor level in the forbidden band is one of the effective ways in the design of visible-light driven materials. There are many reports that the doped photocatalysts and semiconductor electrodes, such as TiO 2 [6][7][8] and SrTiO 3 [9][10][11] respond to visible light. CaTiO 3 (CTO), whose mineral name is perovskite, is one of the best-known wide gap oxides.…”

SiC nanomaterials with different morphologies for photocatalytic hydrogen production under visible light irradiation

“…In order to make full use of solar energy and achieve high efficiency of photocatalytic hydrogen evolution, new photocatalyst systems have been developed. Different modifications were proposed to broaden the absorption edge into the visible region and enhance the photocatalytic activity, including ion doping [8], metal loading [9], addition of sensitizer [10] and combination of photocatalysts [11]. However, these make the preparation of photocatalysts complex and increase the cost in the practical application.…”

Preparation and photocatalytic activities of two new Zn-doped SrTiO3 and BaTiO3 photocatalysts for hydrogen production from water without cocatalysts loading

“…As well known, the recombination and separation/migration processes are two important competitive processes for photoelectronehole pair generated inside a photocatalyst during the photocatalytic water splitting process [16]. Till now, loading noble metals onto different photocatalysts to act as cocatalysts has been demonstrated to be a good approach for the separation of photoelectronehole pair because the loaded noble metals can act as charge transfer sites and/or active sites in the photocatalytic reaction [17,18]. A lot of photocatalysts such as Zn m In 2 S 3þm (m ¼ 1w5, integer) [19], Cr 2 O 3 /CdS [20], b-In 2 S 3 [21], ZnGa 2 O 4 [22] showed interesting photocatalytic activity after loaded with noble metal cocatalysts (Pt, Rh, Pd).…”
