An efficient photocatalyst based on the broadband solar response molecular system was designed and constructed for pollutant degradation in near-neutral conditions via utilizing guest polyoxometalate cluster sensitized with electron deficient host network. Photoelectrochemical analysis reveals electron-hole pairs are generated efficiently upon both visible and NIR light excitation. Its photocatalytic activity in the visible and NIR light regions is enhanced because of the contribution from the broad absorption of copper-viologen framework and the strong host-guest interactions. This stable heterogeneous catalyst is easily recollected and regenerated without the loss of activity for the next cycle.
设计并构建了一种基于宽带太阳响应分子体系的高效光催化剂，用于在近中性条件下通过利用电子缺陷型主体网络敏化的客体多金属氧酸盐簇来降解污染物。光电化学分析表明，可见光和近红外光激发均可有效地产生电子空穴对。由于铜-联吡啶骨架的宽吸收和强主客体相互作用的贡献，其在可见光和近红外光区域的光催化活性得到增强。这种稳定的多相催化剂易于回收和再生，在下一个循环中没有活性损失。
