Solar-driven interfacial evaporation is one of the cutting-edge technologies for seawater desalination and wastewater purification. Herein, a floating carbon-coated silica microsphere/expanded perlite integrated microevaporator (HEPCL) reported. The carbon nanolayer allows HEPCL to have better broadband light absorption performance than natural graphite graphene oxide. Through low density expanded perlite, particles can self-float on water surface self-aggregate into an whole under tension, which enhances heat collection capacity. hierarchical porous structure has continuous Notably, molecules adsorbed in high desorption energy, reduces enthalpy (1621 kJ/kg), making it easy remove with external energy. Thanks design merits, achieves rate 1.551 kg m

Our increasing water demand has been an ongoing critical challenge due to usages in areas such as industrial, agriculture, and domestic household. Conventional production faces challenges, high investment, energy consumption, brine discharge that may be unsustainable the future. Solar steam generation (SSG) recently proposed by many researchers their sustainable green method. Here we demonstrated use of simple manufacturing low-cost dual-layer hydrogel (DLH) system containing a double network positive charged poly-[2-(acryloyloxy)ethyl] trimethyl ammonium chloride (PAETAC) polyvinyl alcohol (PVA) bottom layer for fast transport, well broad light absorbing heat generating PVA/graphene oxide (GO) top evaporation. As result, DLH was able generate 3.12 kg m−2 h−1 evaporation with 92% efficiency under 1 sun (kW m−2) exposure. Furthermore, this design allows safe passive anti-salt bacterial property PAETAC cationic chain, eliminating 99% salt bacteria via Donnan repulsion electrostatic interaction without need sunlight

To alleviate the global freshwater crisis, Janus biomass composite hydrogel evaporator has been designed for remote maneuvering and wind-resistant floating in seawater, showing remarkable self-floating capability, magnetic control, light-absorption, photothermal conversion, water-evaporation, salt exchange, etc. Specifically, top layer contains nanocellulose core-shell nanoparticles with average light absorption of 95 % wavelength range 200-2500 nm can realize manipulation, which makes whole remain stationary at a wind speed 0.76 m/s under control. Its bottom is prepared by foam good property, large pores inside serving as reservoirs promoted material exchange resistant effectively. Under one solar irradiation, its water evaporation rate conversion efficiency reached 2.89±0.09 kg·m-2·h-1 93±2.60 %, respectively. Notably, triple crosslinking network endowed excellent mechanical properties (ultimate stress: 1.6 MPa). After cycles compression, it still stable, resist stress caused wave effectively, displaying stable property long-term desalination tests. Such interfacial solar-driven system exhibits significant applications wastewater purification seawater desalination, offering an environmentally friendly solution clean production.
