Herein, we report the performance of CsPbX (X = Cl, Br, and I) perovskite quantum dots (QDs) for photocatalytic degradation of organic dyes. The photocatalytic performance of CsPbX QDs was characterized by UV-vis absorption spectra and ESI-MS, which evaluated their ability of degrading methyl orange (MO) solution under visible light irradiation. Interestingly, both CsPbCl and CsPbBr QDs show excellent photocatalytic activities, which can decompose the MO solution into a colorless solution within 100 min. This study demonstrates the potential of CsPbX QDs in the degradation of organic dyes and environmentally friendly applications. Moreover, the integration of CsPbX QDs and photocatalysis provides a new insight for the design of new photocatalysts.
在此，我们报告了 CsPbX（X = Cl、Br 和 I）钙钛矿量子点（QDs）在光催化降解有机染料方面的性能。通过紫外可见吸收光谱和 ESI-MS 对 CsPbX QDs 的光催化性能进行了表征，评估了它们在可见光照射下降解甲基橙（MO）溶液的能力。有趣的是，CsPbCl 和 CsPbBr QDs 均表现出优异的光催化活性，可在 100 分钟内将 MO 溶液分解为无色溶液。本研究证明了 CsPbX QDs 在降解有机染料和环保应用方面的潜力。此外，CsPbX QDs 与光催化的结合为新型光催化剂的设计提供了新的思路。
