  随着化石能源的过度开采和使用,产生作为温室气体之一的CO2 大量排放到自然界,生态系统的平衡受到影响,并导致气候变暖日益加剧。利用太阳光催化将CO2 转化成CO 和小分子有机化合物长期以来一直备受关注。我国地域辽阔,有丰富的稀土矿藏资源,我们将稀土金属配合物用于催化CO2 还原反应,构建了可见光催化还原CO2 为CO 的均相催化体系。通过系列优化实验研究,在光催化还原产生CO 和H2 的竞争反应中,提高了产物CO 选择性。在此基础上,基于稀土金属配合物的无机-有机复合材料[1,2]光催化CO2 还原反应的研究结果也将被呈现。

在三氟化硼乙醚和乙腈混合体系中电合成了醇溶性的聚苯绕蒽酮(PBA)[1]。基于PBA设计了一个“开-关”型的荧光传感器用来高选择和高灵敏检测Pd2+[2]。其传感机理可能是因为Pd2+可以和PBA中的两个或多个链节相互作用增强了聚合物链的聚集,从而引起PBA荧光的强淬灭[3,4]。这种基于PBA的荧光传感器被成功用来检测农作物和环境实际样品中的Pd2+。
