Solar-driven photothermal conversion vacuum membrane distillation (SVMD) becomes an energy-efficient water treatment thanks to the thermal localization of photothermal membranes. Membrane photothermal activity and distillation performance are essential for creating photothermal composite membranes. Herein, a CuO/CF-PVDF photothermal composite membrane has been designed with flower-like copper oxide (CuO/CF) photothermal active-layer and polyvinylidene fluoride (PVDF) microporous hydrophobic separation layer. Firstly, the flower-like CuO/CF layer with the light trapping was obtained by in-situ surface oxidation on the copper foam (CF) surface. Then, by the NIPS method, PVDF microporous hydrophobic layer was scraped on one side of the CuO/CF photothermal active-layer and firmly fixed on the porous surface of CuO/CF layer by anchoring effect. The light trap consisted of CuO micron flowers and Cu(OH)2 nanowires. The gaps among the petals increased the light refractive rate and absorption area, thus enhancing the photothermal performance of the CuO/CF. Under 1 kWm-2 solar irradiation, the absorption rate reached up to 95%, and the photothermal conversion efficiency achieved 94%. For the SVMD process, compared to current research, the CuO/CF-PVDF achieved the permeate flux of 3.34 kgm-2h-1 and energy efficiency of 88% under average feed temperature Overall, the CuO/CF-PVDF membrane has promising potential for desalination by fully using sustainable energy. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2COA of Formula: CuH2O2).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. Copper has continued to be one of the most utilized and important transition metal catalysts in synthetic organic chemistry. It is clear from the impact copper catalysis has had on organic synthesis that copper should be considered a first line catalyst for many organic reactions.COA of Formula: CuH2O2
