为了通过人工光合作用高效地将太阳能转化为化学能，我们需要开发具有高量子效率（QE）的可见光响应型光催化剂。在此我们报道一种人工光催化剂（Pt - PdS/CdS）在可见光照射下且有牺牲试剂存在时，在光催化产氢过程中量子效率可高达93%，并且在光催化反应条件下非常稳定。通过在CdS上负载低至0.30 wt%的Pt和0.13 wt%的PdS作为助催化剂，就可实现极高的量子效率。（C）2009爱思唯尔公司。保留所有权利。
To efficiently convert solar energy into chemical energy by artificial photosynthesis, we need to develop visible-light-responsive photocatalysts with a high quantum efficiency (QE). Here we report that an artificial photocatalyst (Pt-PdS/CdS) can achieve a QE up to 93% in photocatalytic H-2 production in the presence of sacrificial reagents under visible light irradiation, and is very stable under the photocatalytic reaction conditions. The extremely high QE could be achieved by loading as low as 0.30 wt% of Pt and 0.13 wt% of PdS as cocatalysts on CdS. (C) 2009 Elsevier Inc. All rights reserved.
