Photo-thermal evaporator based on nickel-cobalt bimetallic oxide

The invention discloses a photo-thermal evaporator based on nickel-cobalt bimetallic oxide. The photo-thermal evaporator comprises a paraffin heat storage layer, a gel water guide layer and a photo-thermal conversion layer. The paraffin heat storage layer, the gel water guide layer and the photo-thermal conversion layer are sequentially placed in the polyethylene foam shell with an opening in the top; the photo-thermal conversion layer adheres to the gel water guide layer, a through hole I extending in the longitudinal direction is formed in the paraffin heat storage layer, and a through hole II corresponding to the through hole I is formed in the bottom of the polyethylene foam shell. The photo-thermal evaporator further comprises a water conveying medium, one end of the water conveying medium makes contact with the gel water guide layer, the other end of the water conveying medium sequentially penetrates through the through hole I and the through hole II and extends out of the through hole II, and when the
