摘要
研究了磺化铝酞菁、磺化锰酞菁作为光敏剂分别在草酸-MSPc体系、TiCl3-MSPc体系、纳米ZnO-MSPc体系中,光照下分解水放氢的研究.实验结果表明:草酸用量对草酸-MSPc体系放氢量有一定影响,超过4mL时氢气量减少;酸性和碱性条件有利于水的光解;在TiCl3-MSPc体系中,最适宜的pH值范围为1～3.
The role of metal sulfo-phthalocyanines was investigated in the system of oxalic acid-MSPc, TiClz-MSPc, ZnO-MSPc. In these systems water can be photolyed to hydrogen under the irradiation of visible light. The experiments showed that the volume of oxalic acid has effect on the volume of H2 which will be reduced if the volume of oxalic acid exceed 4 mL; It will avail photoreduction of water in acidic or basic system; The optimum pH range in the system of TiCl3-MSPc is 1～3.
