Abstract Owing to its photonic band gap (PBG) and slow light effects, aniline black (AB)-poly(vinylidene fluoride) (PVDF) inverse opal (IO) photonic crystal (PC) was constructed to promote the utility of light and realize photothermal synergetic catalysis. As a highly efficient reaction platform with the capability of restricting heat, a microreactor was introduced to further amplify the photothermal effects of near infrared (NIR) radiation. The photocatalytic efficiency of ZnO/0.5AB-PVDF IO (Z0.5A) increases 1.63-fold compared to that of pure ZnO film under a full solar spectrum, indicating the effectiveness of synergetic promotion by slow light and photothermal effects. Moreover, a 5.85-fold increase is achieved by combining Z0.5A with a microreactor compared to the film in a beaker. The photon localization effect of PVDF IO was further exemplified by finite-difference time-domain (FDTD) calculations. In conclusion, photonic crystal-microreactor enhanced photothermal catalysis has immense potential for alleviating the deteriorating water environment.

用于光子定位辅助全太阳光谱光催化的 ZnO/聚（偏二氟乙烯）反蛋白石薄膜的设计

摘要 由于其光子带隙 (PBG) 和慢光效应，苯胺黑 (AB)-聚偏二氟乙烯 (PVDF) 反蛋白石 (IO) 光子晶体 (PC) 被构建以促进光的利用并实现光热。协同催化。作为具有限制热量能力的高效反应平台，引入了微反应器以进一步放大近红外（NIR）辐射的光热效应。在全太阳光谱下，ZnO/0.5AB-PVDF IO (Z0.5A) 的光催化效率比纯 ZnO 薄膜的光催化效率提高 1.63 倍，表明慢光和光热效应协同促进的有效性。此外，与烧杯中的薄膜相比，通过将 Z0.5A 与微反应器结合，实现了 5.85 倍的增加。PVDF IO 的光子定位效应通过有限差分时域 (FDTD) 计算得到了进一步的例证。总之，光子晶体-微反应器增强的光热催化在缓解日益恶化的水环境方面具有巨大的潜力。
