Currently, the treatment of wastewater that contains organic dyes and bacteria attracts a considerable amount of attention, and the fabrication of photoinduced catalytic materials to address the problem is still a challenge. In this work, indium(III) sulfide hybrid gels are prepared by in situ polymerization and sulfurization using In(III) metal–organic gels as sacrificial templates. Two In(III) metal–organic gels are fabricated by the coordination interaction between multitopic pyridyl ligands and indium ions, where the assembled structure of the gel templates can be tuned by employing different multitopic ligands to obtain the networks of nanofibers and nanoparticles. After templated fabrication, the resulting In2S3-polymer hybrid gels show improved mechanical strength, and can be used as novel photocatalysts for the photodegradation of organic dyes, such as rhodamine B and methylene blue, and efficient adsorbents for the adsorption of anionic dyes, such as Congo red. Experiments that involve pure and mixed bacteria demonstrate the bacteria-removing activities of the hybrid gels due to their electrostatic adsorption and photoinduced sterilization of the bacteria. Therefore, this new kind of hybrid gel might have potential applications in the photoinduced purification of water by scavenging organic dyes and bacteria in the aqueous phase.

源自 In(III) 金属-有机凝胶的 In2S3-聚合物混合凝胶,用于染料吸附、光降解和细菌去除

目前,含有机染料和细菌的废水的处理引起了相当多的关注,而制备光诱导催化材料来解决该问题仍然是一个挑战。在这项工作中,使用 In(III) 金属-有机凝胶作为牺牲模板,通过原位聚合和硫化制备了硫化铟 (III) 混合凝胶。通过多位吡啶基配体和铟离子之间的配位相互作用制备了两种 In(III) 金属-有机凝胶,其中凝胶模板的组装结构可以通过使用不同的多位配体来调整以获得纳米纤维和纳米颗粒的网络。模板化制造后,得到的 In 2 S 3聚合物混合凝胶显示出更高的机械强度,可用作新型光催化剂用于有机染料(如罗丹明 B 和亚甲蓝)的光降解,以及用于吸附阴离子染料(如刚果红)的高效吸附剂。涉及纯细菌和混合细菌的实验证明了混合凝胶由于其静电吸附和光致细菌杀菌而具有除菌活性。因此,这种新型混合凝胶通过清除水相中的有机染料和细菌,可能在光诱导水净化中具有潜在应用。
