Hydrothermal synthesis of visible light active zinc-doped tin disulfide photocatalyst for the reduction of aqueous Cr(VI)

Cellulose/SnS2 composite with enhanced visible-light photocatalytic activity prepared by microwave-assisted ionic liquid method

“…[9][10][11][12] To date, a variety of methods have been adopted for the synthesis of well dened SnS 2 nanostructures with different morphologies including solvothermal process, hydrothermal process, mechanochemical route, solid state reactions, pyrolysis of organotin precursor, and tetrabutyltin precursor. [13][14][15][16][17] However, many of them involved harsh reaction conditions such as high temperature, high pressure or complex preparation procedures. Therefore, it remains a big challenge to develop a simple and facile synthesis which requires only mild reaction conditions under normal atmospheric pressure and room temperature.…”

Effective Modulation of Optical and Photoelectrical Properties of SnS2 Hexagonal Nanoflakes via Zn Incorporation

“…Figure 5d shows the XPS spectrum for Zn in SnS 2 nanoflakes. Besides, the Zn 2p 3/2 peak appeared at 1021.3 eV is attributed to Zn 2+ bonding state [43], confirming Zn 2+ ions have been incorporated into the SnS 2 .…”

Photocatalyst Bi(OH)SO4 · H2O with High Photocatalytic Performance

“…That is because their p orbital energy levels are higher than the 2p orbit of oxygen, mixing with the O2p orbit or forming a lower valence band independently, the band gap can be narrowed and the spectral response range can be extended. Another way is to introduce elements with a d10 electronic configuration such as silver zinc [26][27][28][29]. In this work, a novel photocatalyst Bi(OH)SO4•H2O with high oxidation ability theoretically is prepared by a facile method.…”
