A stable 0D/1D photocatalyst constructed by ZnSnO₃ quantum dots (QDs) and perylene diimide (PDI) supramolecular nanorods was successfully achieved via a simple in situ deposited method through an electrostatic attraction build-up strategy and exhibited marvel phenol degradation efficiency under visible-light irradiation. By engineering controllable 0D/1D hetero-interfaces, on the one hand, most of the light absorption sites from the PDI component remained exposed and, on the other hand, efficient interfacial charge transfer driven by a giant built-in electric field between the two components successfully led to great enhancement in charge separation. Importantly, besides the evidenced excellent structure and morphology stability, suppressed production of PDI^·– after forming the heterostructure was also proved to be responsible for its robust cyclic photocatalytic activity. This stable and efficient visible-light-driven photocatalyst showed great development potential for removal of phenol pollutants with low concentrations.

用于高效降解苯酚的 ZnSnO3 量子点/苝二亚胺超分子纳米棒异质结光催化剂

由 ZnSnO ₃量子点 (QDs) 和苝二亚胺 (PDI) 超分子纳米棒构建的稳定的 0D/1D 光催化剂通过简单的原位沉积方法通过静电吸引建立策略成功实现，并在可见光下表现出惊人的苯酚降解效率。光照射。通过设计可控的 0D/1D 异质界面，一方面，来自 PDI 组件的大部分光吸收位点仍然暴露在外，另一方面，由两者之间的巨大内置电场驱动的有效界面电荷转移组件成功地导致电荷分离的极大增强。重要的是，除了已证明的优异结构和形态稳定性外，还抑制了 PDI 的产生^·-在形成异质结构后也被证明是其强大的循环光催化活性的原因。这种稳定高效的可见光驱动光催化剂在去除低浓度苯酚污染物方面显示出巨大的发展潜力。
