摘要: 本文合成了一种水溶性的Pt(II)-Salen配合物(Salen=双5-磺酸钾水杨醛合邻苯二胺席夫碱),将其用于光催化制氢.研究发现在光催化制氢体系中仅存在Pt(II)-Salen配合物和三乙胺(TEA)而没有额外加入催化剂时,在可见光照射下有氢气产生.进一步的研究表明,Pt(II)-Salen配合物在体系中既是光敏剂,又是催化剂Pt纳米粒子的前体.同时,制氢体系中除了TEA外没有使用有机溶剂.该结果为简化多组分制氢体系提供了新思路.

Abstract: A new water-soluble Pt(II) -Salen complex (Salen=NN'-substituted bis(salicyl-aldimine-5-sulphonic acid) potassium salt) was synthesized, characterized and employed in the photocatalytic hydrogen evolution system. In the presence of TEA, this system could produce hydrogen effectively without additional catalyst. An investigation found that the Pt(II) -Salen complex could be employed as photosensitizer. Besides, it could also be the precursor of the catalyst. In addition, there was not organic solvent except TEA in the hydrogen evolution system. The result provided a new way to simplify the multi-component system for photocatalytic hydrogen production.

Key words: water-soluble, platinum(II) complex, Salen, photocatalytic hydrogen production
