要旨

Solar powered local interface evaporation has high conversion efficiency, water purification, seawater desalination, power generation and other potentials. However, the ineffective integration and expensive materials of hybrid solar thermal devices undermine the widespread development and practical outdoor use of solar energy. This article proposes a low-cost and sustainable 3D carbonated sucrose evaporator that achieves broadband light absorption, thermal insulation, and high hydrophilicity for high-performance water evaporation and self-desalination. The dome array structure not only effectively reduces the diffuse reflection of light, but also significantly increases the solar evaporation rate with excellent salt resistance and long-term stability. A high evaporation rate of 3.54 kg m−2 h−1 and an efficiency of 95.86% were achieved under one sun illumination, and the evaporation rate was 3.48 kg m−2 h−1 h even in high-salinity brine (15 wt% NaCl solution). In addition, the synergistic coupling of solar-steam and solar-electricity technologies can simultaneously achieve a high evaporation rate of 3.43 kg m−2 h−1 and an output power of 0.48 W m−2, providing great hope for people in developing regions to cope with freshwater and electricity shortages.

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry A are listed below. This list is neither exhaustive nor exclusive. Artificial photosynthesis Batteries Carbon dioxide conversion Catalysis Fuel cells Gas capture/separation/storage Green/sustainable materials Hydrogen generation Hydrogen storage Photocatalysis Photovoltaics Self-cleaning materials Self-healing materials Sensors Supercapacitors Thermoelectrics Water splitting Water treatment
