Abstract
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.
摘要
一种锡(II)钨硅酸盐衍生物 K(11)H[Sn(4)(SiW(9)O(34))(2)]·25H(2)O，其中包含四个夹心 Sn(2+) 阳离子，是通过 SnCl(2)、KCl 和 Na(10)[α-SiW(9)O(34)]·xH(2)O 的反应制备的。在 Pt 纳米粒子作为共催化剂和甲醇作为牺牲剂的情况下，观察到可见光光催化 H(2)释放活性。
