Visible-light-driven oxidation of sulfides has attracted the profound attention to synthesize sulfoxides and purify mustard gas simulant. In this work, a series of visible-light-responsive polyoxometalate-based porous cationic polymers, i.e. SiW-PCP , PW-PCP , SiW-PCP , SiW-PCP , SiW-PCP (PCP = porphyrin-based porous cationic polymer), were synthesized by ion exchange process. These POM-PCPs exhibit excellent ability of trapping visible light due to their built-in porphyrin units, which can rapidly oxidize sulfides and degrade 2-chloroethyl ethyl sulfide (CEES) in the presence of a 10 W white LED light and O. Benefiting from the synergistic effect between [SiW] and PCP, hybrid has the highest photocatalytic efficiency, attaining 99 % conversion of sulfides within 16 min and 99 % CEES purification in 8 min, much higher than PCP precursor. The reaction mechanism reveals that both O and O are involved in the photocatalytic process. What's more, hybrid has remarkable applicability to numerous sulfides and robust six-round recycling with no reduction in catalytic efficiency.

将多金属氧酸盐限制在卟啉基多孔阳离子聚合物中，以促进可见光驱动的亚砜合成和芥子气模拟物的解毒


硫化物的可见光驱动氧化在合成亚砜和纯化芥子气模拟物方面引起了人们的广泛关注。在这项工作中，一系列可见光响应的基于多金属氧酸盐的多孔阳离子聚合物，即SiW-PCP、PW-PCP、SiW-PCP、SiW-PCP、SiW-PCP（PCP=基于卟啉的多孔阳离子聚合物），采用离子交换法合成。这些 POM-PCP 由于其内置的卟啉单元而表现出优异的捕获可见光的能力，在 10 W 白色 LED 灯和 O 存在的情况下，可以快速氧化硫化物并降解 2-氯乙基乙基硫醚 (CEES)。由于[SiW]和PCP之间的协同效应，杂化物具有最高的光催化效率，在16分钟内实现硫化物99%的转化，在8分钟内实现99%的CEES纯化，远高于PCP前驱体。反应机理揭示了O和O都参与了光催化过程。更重要的是，混合动力对多种硫化物具有显着的适用性和强大的六轮回收能力，且催化效率不会降低。
