PAF-45 with a wholly aromatic framework, intrinsic microporosity and π-π conjugation system shows excellent performance in aromatic pollutant removal. It exhibits a high adsorption capacity for the benzene series and moderate photocatalytic performance. As an adsorbent, PAF-45 can adsorb 35 wt% benzene and 68 wt% chlorobenzene in static adsorption experiments at room temperature and pressure. In benzene simulation wastewater, PAF-45 also shows excellent adsorption capacity, without significant reduction after 10 cycles of the adsorption-desorption process. Moreover, PAF-45 exhibits an impressive photocatalytic degradability of aromatic compounds, like aniline and phenol, under visible light illumination.
具有全芳香骨架、固有微孔性和π-π共轭体系的PAF-45在去除芳香族污染物方面表现出优异性能。它对苯系物具有高吸附容量和适度的光催化性能。作为吸附剂，在室温和常压下的静态吸附实验中，PAF-45能吸附35 wt%的苯和68 wt%的氯苯。在苯模拟废水中，PAF-45也显示出优异的吸附容量，在10次吸附-解吸循环后没有显著降低。此外，在可见光照射下，PAF-45对苯胺和苯酚等芳香族化合物表现出令人印象深刻的光催化降解能力。
