Continuous, stable, light and heat / high speed interface Joule heat assisted evaporation desalination
Carbon material has a very broad application prospects in energy capture, storage and utilization. In recent years, the use of high efficiency solar evaporation interface has become a new hotspot, a number of new materials in the carbon material is particularly excellent. Evaporation using interface may provide new solutions for the efficient use of clean energy, desalination, waste water treatment and the like. Subject to a lower energy density of sunlight (1 kW m 2 ), the new material can be achieved Most solar thermal evaporation rate of the interface is still at a low level, only the natural evaporation rate (0.5 kg m is about 3 times 2 h 1) of the. Moreover, the use of solar thermal interface to achieve the evaporation rate is not stable enough, affected by weather, sunlight and other factors irradiation diurnal variation, poor use under cloudy day, night, indoor and other environmental effects. Adopt measures to enhance the physical device convergence solar energy, high cost, which is currently a lot of solar energy equipment is difficult to promote the use of one of the main reasons a large area. Power supply clean energy (e.g., solar, wind, etc.) have been based on large-scale applications, especially in off-line power yearly costs for new energy supply interface provides new opportunities evaporated. Recently, Shanghai Jiaotong University Associate Professor Zhao Bin Yuan (Associate Professor Binyuan Zhao) Task Force and the City University of London (City, University of London) George Dennis Assistant Professor, International Chemical Industry Association (Society of Chemical Industry, SCI) Chairman of the British branch of Dr. WU Weiping (Dr Weiping Wu) Research Group, Department of materials at Oxford University Professor Robert Bradley [123 ] cooperation , the mesoporous carbon – copolymer complex structure to achieve the wind, solar thermal evaporation interface, Advanced Functional Materials, 28, 1870332, 2018, https://onlinelibrary.wiley.com/doi/ 10.1002 / adfm.201870332,https://onlinelibrary.wiley.com/doi/abs/10.1002/adfm.201803266, environment-friendly multi-level and large pore carbon material photothermal evaporation, based RSC Advances, 9, 29414, 2019 and other previous work, [ 123] achieved sustained, stable, high rate of evaporation interface aspects important progress . They based nano-optical surfaces and super metamaterial principle, a combination of new ideas +-dimensional two-dimensional (1D + 2D) material design, invented a new flexible graphene / carbon fiber sheet to all carbon-based composite material rGO-CC, and design of composite – hydrophilic fiber cloth – foam insulating layer structure for electric and photothermal evaporation. Wherein skillfully with CFRP composite material in which the carbon is deposited electrochemically deposited on the surface oxidized graphite fiber, and graphite oxide in situ by the Joule heat of the electric heat-reduction, the preparation of graphene /. The work as a positive cover (Figure 1), published in Wiley\’s journals Advanced Sustainable Systems on (Graphene-Carbon Composites for Solar and Low-Voltage Powered Efficient Interfacial Evaporation. Advanced Sustainable Systems, 4, 1900122, 2020), PhD Liu Fenghua (Fenghua Liu) is the first author of the paper, Associate Professor Zhao Bin yuan and Dr. WU Weiping for the corresponding author.
