    To solve the problems of low utilization over the solar spectrum, elevating the photon absorption efficiency and exploiting long-wavelength photons are of great significance. Herein, a CdSe/polydopamine(PDA)@SiO2 core-shell opal photonic crystal structure with excellent photothermal effect and photon absorption was fabricated for the first time. The photonic bandgap (PBG) effect and the slow photon effect of the photonic crystal structure helps the absorbi... ...点击完成人机验证后继续浏览

    为了解决太阳能光谱利用率低的问题，提高光子吸收效率和利用长波长光子具有重要意义。在此，首次制备了一种CdSe/聚多巴胺（PDA）@SiO₂核壳结构光子晶体，该结构具有优异的光热效应和光子吸收性能。光子带隙（PBG）效应和光子晶体结构中的慢光子效应有助于提高光子吸收效率，而PDA涂层外壳提供的光热效应则为光催化反应提供了更高的温度。因此，S2P0样品（未涂覆PDA）的PBG与CdSe光催化剂的吸收边缘一致，其二氧化碳还原效率提高了三倍。得益于PDA的光热效应，S2P20样品（20% PDA涂层）比空白样品的效率提升了4.77倍，证明了设计的有效性。此外，PDA外壳增强了光子晶体薄膜的附着力，并在纺织品等领域展示了其他应用潜力。这项工作展示了一种利用光热效应和光子晶体结构协同作用进行高效二氧化碳光还原的方法，并揭示了更多潜在的应用。
