Efficient photocatalytic degradation of gaseous acetaldehyde over ground Rh–Sb co-doped SrTiO₃ under visible light irradiation

Abstract

A visible-light-responsive Rh–Sb co-doped SrTiO3 photocatalyst (STO:Rh,Sb) via a solid-state reaction was successfully developed, following pulverization by using ball-milling.

Transition Metal Doping Induces Ti3+ to Promote the Performance of SrTiO3@TiO2 Visible Light Photocatalytic Reduction of CO2 to Prepare C1 Product.

“…In the past research reports, many different metal elements have been doped into the SrTiO 3 crystal lattice. (Ag and Pb, [10,11] Ta and Ni, [12] Cr, [13] La and Nb, [14,15] Mn, Co, Fe, [16,17] Al, [17,18] Cu, [17,19] Pt and Rh, [20][21][22] Sb and Ru, [22,23] Bi, [24] ). In these researches on doped strontium titanate materials, most of them are applied in the fields of synthetic ceramics, photocatalytic decomposition of water, photodegradation of organic pollutants, and electrocatalysis.…”

Insight into the enhanced photocatalytic activity of Mo and P codoped SrTiO3from first-principles prediction

“…at the host Ti sites in SrTiO 3 has shown to lower the band gap by introducing localized 3d impurity states, shiing the absorption spectra threshold towards the visible region. [24][25][26][27] Recently, the substitution of non-metal and metal cations at the Ti sites in TiO 2 has stimulated great interest in enhancing the visible-light absorption and photocatalytic activity by including (Fe + Si), (Mo + P) and (W + P) codoping. [28][29][30] However, to the best of our knowledge, there is no reported experimental or theoretical work focusing on the synergistic effects of (Mo + P) codoped SrTiO 3 on the band gap engineering.…”

Homogeneous Doping of Substitutional Nitrogen/Carbon in TiO2 Plates for Visible Light Photocatalytic Water Oxidation

“…Developing visible light responsive photocatalysts has been actively pursued in order to fully utilize visible-light dominant solar light. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] Stable metal oxide semiconductors with suitable electronic structures as promising photocatalysts usually suffer from their large bandgap of over 3 eV so that little visible light can be absorbed. [18][19][20][21] To overcome this bottleneck, various strategies, in particular anion doping, [22][23][24][25] have been attempted to change the electronic structures of metal oxides to narrow bandgap for the absorption of low energy photons.…”
