贵金属Pt作为一种高效的光催化制氢助催化剂已被广泛应用。然而，不希望的氢氧化反应也可以同时被金属Pt催化。本文采用水热法在CdS纳米花上原位负载单分散的Pt纳米团簇（Pt NCs），并在N2气氛下进行高温热处理，增强了CdS和Pt之间的相互作用，增加了Pt NCs中Pt 0的比例.值得注意的是，少量Pt 2+在Pt NC中的共存有助于有效地抑制不利的氢反氧化。所得到的Pt-CdS复合材料显示出扩展的可见光响应和高效的光生电荷分离。结果表明，所制备的Pt-CdS复合材料不仅具有上级的光催化产氢速率，而且大大降低了贵金属Pt的用量，在实际利用太阳能作为燃料方面具有潜在的应用前景。
Noble metal Pt has widely been used as a highly effective co-catalyst for the photocatalytic H2generation. However, the undesirable hydrogen oxidation reaction can also be simultaneously catalyzed by metal Pt. Herein,in situthermal-assisted loading of monodispersed Pt nanoclusters (Pt NCs) on the CdS nanoflowers have been achieved by a hydrothermal method following with a high-temperature thermal treatment under N2atmosphere, leading to an enhanced interaction between CdS and Pt, as well as an increased proportion of Pt0in Pt NCs. Notably, the co-existence of a small amount of Pt2+in Pt NCs help to suppress the unfavorable hydrogen back-oxidation effectively. The resulting Pt-CdS composite shows an extended visible-light response and a highly efficient photo-generated charges separation. As a result, the as-prepared Pt-CdS composite not only possesses a superior photocatalytic hydrogen production rate, but also greatly reduces the usage of noble metal Pt, which holds a potential promise in practical utilizing of solar energy for the fuel generation.
