The application belongs to the technical field of solar light utilization, and discloses a solar light energy optical fiber leading-in system with fixed lenses; the system comprises a lens mounting module, which is used for fixing and mounting convex lenses on the outer vertical wall surface of a building; and a sun position determining module, which is used for determining the real-time position of the sun through an astronomical algorithm; the application can flexibly select two kinds of focus-pursuing modes according to different situations, so as to ensure that the solar light energy is effectively and quickly led into the input end of the optical fiber, the optimal degree of freedom combination set of the mirror array corresponding to the real-time position of the sun is quickly determined, the fast focus-pursuing is realized, the focal point spots reflected by the mirrors are accurately superimposed on the input end of the optical fiber, and the focal point spot intensity of the input end of the optical fiber is maximized; the fast focus-pursuing of the input end of the optical fiber is also realized, the focus-pursuing time is reduced, the current optical fiber input end position which is not fixed is adjusted, and the solar light can be accurately led into the input end of the optical fiber.

This invention relates to the field of metal-organic framework (MOF) functional materials technology, specifically to a plasmonic MOF composite catalyst, its preparation method, and its application. The composite catalyst has a core-shell structure, comprising: a core containing gold nanoparticles exhibiting plasmonic effects; a shell coating the surface of the core, comprising a zinc-containing MOF material; and metal ions introduced and loaded into the zinc-containing MOF material via bridging molecules, wherein the bridging molecules are small organic molecules containing -NH2 groups. This invention effectively overcomes the electrostatic repulsion effect caused by the electropositivity of the zinc-containing MOF surface through the coordination interaction between the -NH2 groups in the bridging molecules and the metal ions, achieving effective introduction of metal ions within the framework. The resulting composite catalyst exhibits excellent catalytic activity and selectivity in the photoelectrochemical reduction of nitrate to ammonia.
