1An all-in-one FeO_(x)-rGO sponge fabricated by solid-phase microwave thermal shock for water evaporation and purification显示文摘Developing high-efficiency photothermal seawater desalination devices is of significant importance in addressing the shortage of freshwater.Despite much effort made into photothermal materials,there is an urgent need to design a rapidly synthesized photothermal evaporator for the comprehensive purification of complex seawater.Therefore,we report on all-in-one FeOx-rGO photothermal sponges synthesized via solid-phase microwave thermal shock.The narrow band gap of the semiconductor material Fe_(3)O_(4) greatly reduces the recombination of electron-hole pairs,enhancing non-radiative relaxation light absorption.The abundantπorbitals in rGO promote electron excitation and thermal vibration between the lattices.Control of the surface hydrophilicity and hydrophobicity promotes salt resistance while simultaneously achieving the purification of various complex polluted waters.The optimized GFM-3 sponge exhibitedan enhanced photothermal conversion rate of 97.3% and a water evaporation rate of 2.04 kg/(m^(2)·hr),showing promising synergistic water purification properties.These findings provide a highly efficient photothermal sponge for practical applicationsof seawater desalination and purification,as well as develop a super-rapid processing methodology for evaporation devices.Youkun Sun Xiuwen Zhao Xueling Song Jinchen Fan Junhe Yang Yingchun Miao Shuning Xiao 2024Journal of Environmental Sciences2024,,4:0
