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 NIR light excitation. Its photocatalytic activity regions is enhanced because of contribution from broad absorption copper-viologen framework strong host-guest interactions. This stable heterogeneous catalyst easily recollected regenerated without loss next cycle.
