Solar steam generation provides an efficient, sustainable, and affordable strategy for freshwater extraction from seawater and wastewater to effectively deal with the water shortage crisis. However, it still faces poor durability because the salting-out effect always leads to a decrease in the evaporation rate at high salt concentrations To address this issue, we designed mushroom-like micro/nanostructured graphene nanosheets/copper sulfide nanowires (graphene/Cu7S4) on Cu foam with Janus-type wettability by in situ oxidation of Cu foam and precipitation conversion, followed by the dip-coating method. The superhydrophilic Cu7S4 nanowires are endowed with the function of water supply and thermal insulation, and the hydrophobic graphene nanosheets are granted with the function of light absorption and water evaporation Under one sun illumination, the graphene/Cu7S4 foam with Janus-type wettability exhibits a high water evaporation rate of up to 2.78 kg m-2 h-1 and long-term stability for brine evaporation The excellent performances are ascribed to a fast water supply and a salt-rejecting effect due to the capillarity forces and high porosity. This solar steam generation with the Janus-type wettability has broadened the potential applications of seawater desalination, wastewater purification, and sterilization. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Electric Literature of CuH2O2).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. Copper catalyst has received great attention owing to the low toxicity and low cost. Copper nanoparticles can also catalyze the coupling reaction of nitrogen-containing nucleophiles, phenols, thiols, xanthogenates, selenium ruthenium nucleophiles and the like.Electric Literature of CuH2O2
