▎ 摘　　要

NOVELTY - Ultra-efficient full spectrum photo-thermal conversion composite material, comprises the composite material compounded by any two large groups consisting of tungsten oxide, titanium oxide, copper sulfide or a carbon-containing material, and group consisting of iron oxide, carbon nitride or noble metal group. USE - The ultra-efficient full spectrum photo-thermal conversion composite material is useful for sewage treatment, seawater desalination or desalination treatment (claimed). ADVANTAGE - The ultra-efficient full-spectrum photothermal conversion composite material: has photocatalytic properties; forms a porous fiber film or a porous foam layer with plastic, and is combined with a hydrophilic fiber layer to form a composite layer structure with high light-to-heat conversion efficiency, and has single-guiding and photocatalytic performance; has the ability to absorb full-spectrum wavelengths, and can efficiently convert light energy directly into thermal energy under light sources, and especially sunlight; improves the problem of inefficient conversion efficiency, in which existing energy conversion is limited to a specific wavelength range. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: an ultra-efficient full spectrum photo-thermal conversion composite material film layer, comprising the ultra-efficient full spectrum photothermal conversion composite material and a porous fiber film layer or porous foaming film layer obtained by plastic; and an ultra-efficient full spectrum photo-thermal conversion composite layer structure, comprising mutually laminated: ultra-efficient full spectrum photo-thermal conversion composite material film layer, comprising ultra-efficient full spectrum photo-thermal conversion composite material and a plastic obtained porous fiber film layer or porous foaming film layer, and a hydrophilic fiber layer. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an ultra-efficient full spectrum photo-thermal conversion composite layer structure. 10Super-efficient full spectrum photoinduced heat conversion layer 11Composite electro-spinning fiber layer 13Hydrophilic fiber layer 111Composite electro-spinning fiber 111ASuper-efficient full spectrum photo-thermal conversion material 111BPlastic
