Abstract | Simultaneously satisfying recovery and efficient degradation remains a challenge for photocatalysis in pollutant treatment. Hence, Cu-ZIF-67 loaded rGO/PVA aerogel (Cu-ZIF-67/rGO/PVA) is prepared by thermal reduction and surface growth, which boosts photocatalytic rate of recyclable aerogel by utilizing concomitant heat to enhance mass transfer by interfacial evaporation. The Cu ions doping of ZIF-67 advances the overlapping of its absorption band with sunlight and accelerates the separation of the photogenerated hole-electron. PVA based aerogel provides mechanical strength for loading and recycling of Cu-ZIF-67. rGO provides an excellent conductive substrate to extract and transport charge carriers to the reaction site while enhancing solar energy absorption and interfacial evaporation efficiencies. The evaporation rate of Cu-ZIF-67/rGO/PVA could reach 1.95 kg m-2 h-1 under 1 kW m-2 simulated solar illumination, and the photothermal conversion efficiency could reach 92.1%. Highly efficient thermal conversion promotes rapid localized warming of the Cu-ZIF-67/rGO/PVA, accelerating the production of reactive oxidants and enhancing their reactivity. Under one solar intensity, the degradation of MB by Cu-ZIF-67/rGO/PVA was significantly improved, increasing from 14.79% to 78.52%. Moreover, Cu-ZIF-67/rGO/PVA has excellent salt resistance. Therefore, Cu-ZIF-67/rGO/PVA shows strong potential for synergistic photocatalytic degradation of organic pollutants via interfacial evaporation, providing a novel approach for complex pollutant treatment. |
