Highly Efficient Photocatalytic H2 Evolution from Water using Visible Light and Structure-Controlled Graphitic Carbon Nitride**
The major challenge of photocatalytic water splitting, the prototypical reaction for the direct production of hydrogen by using solar energy, is to develop low-cost yet highly efficient and stable semiconductor photocatalysts. Herein, an effective strategy for synthesizing extremely active graphitic carbon nitride (g-C3N4) from a low-cost precursor, urea, is reported. The g-C3N4 exhibits an ext...
متن کاملA novel sandwich-type polyoxometalate compound with visible-light photocatalytic H2 evolution activity.
A tin(II) tungstosilicate derivative K(11)H[Sn(4)(SiW(9)O(34))(2)]·25H(2)O with four sandwiched Sn(2+) cations was prepared by reaction of SnCl(2), KCl and Na(10)[α-SiW(9)O(34)]·xH(2)O. Visible-light photocatalytic H(2) evolution activity was observed with Pt nanoparticles as co-catalyst and methanol as sacrificial agent.
متن کاملSolar light-driven photocatalytic hydrogen evolution over ZnIn2S4 loaded with transition-metal sulfides
A series of Pt-loaded MS/ZnIn2S4 (MS = transition-metal sulfide: Ag2S, SnS, CoS, CuS, NiS, and MnS) photocatalysts was investigated to show various photocatalytic activities depending on different transition-metal sulfides. Thereinto, CoS, NiS, or MnS-loading lowered down the photocatalytic activity of ZnIn2S4, while Ag2S, SnS, or CuS loading enhanced the photocatalytic activity. After loading ...
متن کاملPhase-dependent photocatalytic H2 evolution of copper zinc tin sulfide under visible light.
CZTS exhibited apparently phase-dependent photocatalytic H2 evolution under visible light. Possible factors for the phase-dependent photocatalytic activity of CZTS were discussed in detail.
متن کاملSoft-template Synthesis of Mesoporous Carbon Nitride with Enhanced Photocatalytic H2 Evolution under Visible Light
Experimental Section 1. Materials Melamine, sulfuric acid (H 2 SO 4) and triethanolamine were purchased from Chengdu Kelong Chemical Reagent Factory. Pluronic P123 was purchased from Aldrich. All reagents were used as received without further treatment. 2. Synthesis of mesoporous graphitic carbon nitride The following is a typical procedure for synthesis of worm-like mesoporous graphitic carbon...
