The invention discloses a solar water evaporation purification and decomposition device which comprises a water supply line, a float and heat insulation layer, an evaporation layer and a photothermalconversion and solute barrier layer which are connected in sequence from bottom to top. The water supply line enables water to pass through the float and heat insulation layer, and the water is pumpedinto the evaporation layer by virtue of a capillary action; solar energy absorbed by the photothermal conversion and solute barrier layer is converted into heat, and water is heated to be vaporized into water vapor from the evaporation layer; due to pore channel volatilization of the photothermal conversion and solute barrier layer, partial water vapor is decomposed to produce hydrogen and oxygen; since the photothermal conversion and solute barrier layer contains a hydrophobic part and is not infiltrated by water, the solar energy can directly heat a heat-absorbing material only, but not heat water, so that high photothermal conversion efficiency is realized; and meanwhile, the solute in the water is prevented from being separated out on the membrane, and sea water desalination, sewage purification and water decomposition can be realized. Due to the design of a hydrophilic/hydrophobic double-layer evaporation structure, the solar water evaporation purification and decomposition device with high photothermal conversion efficiency and high stability is obtained.
