The invention belongs to the technical field of photoelectric materials, and particularly relates to a Ti3C2 / WO3 Schottky heterojunction photoanode and a preparation method and application thereof. The preparation method of the photo-anode comprises the following steps: (1) coating a Ti3C2 dispersion liquid on a conductive surface of pretreated conductive glass to obtain conductive glass with a Ti3C2 layer on the surface; (2) coating a tungstic acid mixed solution on the Ti3C2 layer, and drying to obtain conductive glass with tungstic acid / Ti3C2 on the surface; and (3) putting the conductive glass with the tungstic acid / Ti3C2 on the surface into a precursor solution for growing WO3 in a manner that the conductive surface faces downwards to carry out hydrothermal reaction, and then cleaning, drying and calcining to obtain the Ti3C2 / WO3 Schottky heterojunction photo-anode. The Schottky heterojunction photo-anode prepared by the method can promote the separation of photon-generated carriers, so that the photoelectrocatalysis performance is improved.

This invention relates to the field of materials technology, and more particularly to a 3D-printed, internally hollowed-cone solar interface evaporator with directional salt deposition function, its preparation method, and its application. The invention includes step 1: three-dimensional model construction; step 2: substrate surface pretreatment and chemical activation; and step 3: hydrothermal preparation of a Co-Bi-S coating. This invention uses a 3D-printed porous, internally hollowed-cone resin device as a substrate, and grows a Co-Bi-S coating in situ on its surface using a hydrothermal method. This coating exhibits both excellent photothermal conversion performance and corrosion resistance. The evaporator structure is designed as a porous, internally hollowed-cone shape, which provides a larger evaporation area, stronger light capture and focusing capabilities, and can achieve higher evaporation temperatures and directional salt deposition effects. The prepared solar interface evaporator exhibits excellent photothermal conversion performance and water evaporation efficiency, and also demonstrates good structural stability and corrosion resistance. This solves the technical problems of low photothermal conversion efficiency and poor stability in high-salt environments inherent in traditional solar evaporators, making it suitable for applications such as seawater desalination.
