“…examined the effects of unwanted evaporation on the total evaporation rate of 2D materials. [ 4b ] Four different samples, namely: 58 mm disc (58D), 40 mm square (40S), 30 mm square (30S) and 20 mm square (20S) were tested in a 58 mm diameter beaker with changing conditions by eliminating unwanted evaporation with parafilm and limiting the aperture to the surface area of the evaporator. The 58D sample produced an evaporation rate of 1.18 kg m −2 h −1 , while the 40, 30, and 20S evaporated 1.52, 2.57, and 5.07 kg m −2 h −1 , respectively.…”

Recent advances in solar‐driven interfacial evaporation (SDIE) have led to high evaporation rates that open promising avenues for practical utilization in freshwater production and industrial application for pollutant and nutrient concentration, and resource recovery. Breakthroughs in overcoming the theoretical limitation of 2D interfacial evaporation have allowed for developing systems with high evaporation rates. This study presents a comprehensive review of various evaporator designs that have achieved pure evaporation rates beyond 4 kg m−2 h−1, including structural and material designs allowing for rapid evaporation, passive 3D designs, and systems coupled with alternative energy sources of wind and joule heating. The operational mechanisms for each design are outlined together with discussion on the current benefits and areas for improvement. The overarching challenges encountered by SDIE concerning the feasibility of direct integration into contemporary practical settings are assessed, and issues relating to sustaining elevated evaporation rates under diverse environmental conditions are addressed.

“…The theoretical evaporation rate limit for SDIE in 2D systems at 1 Sun irradiation (1000 Wm −2 ) is only 1.47 kg m −2 h −1 and so, to improve the utility of SDIE systems, higher evaporation rates with robust and long‐term sustainable operations should be addressed. [ 4 ]…”

“…With rapid population growth and water pollution, freshwater scarcity has become a serious problem. , Solar radiation, as a green and sustainable energy source, provides potential energy for water purification, especially for solar interfacial evaporation. − Compared with traditional solar evaporation technologies (such as bottom heating and bulk heating), interfacial evaporation can absorb solar radiation on the evaporation surface and lead to local heating for evaporation, thus improving the solar evaporation efficiency (>80%). − For example, Au nanocages were incorporated into the electrospinning nanofibers of polyvinylidene fluoride (PVDF) and TiO 2 @TiN branched nanowires on carbonized wood for solar water evaporation, , and nonwoven-based reduced graphene oxide had superior solar thermal conversion properties and self-cleaning capabilities, and a higher evaporation rate was achieved . In addition, both interfacial solar evaporation and thermoelectric power generation can be achieved by a flexible solar evaporator …”

Solar-driven interfacial evaporation has caught wide attention for water purification due to its green and environment-friendly properties. The key issue is how to effectively utilize solar radiation for evaporation. To fully understand the thermal management of the solar evaporation process, a multiphysics model has been built by the finite element method to clarify the heat transfer process for the improvement of solar evaporation. Simulation results indicate that the evaporation performance can be improved by tuning the thermal loss, local heating, convective mass transfer, and evaporation area. The thermal radiation loss of the evaporation interface and thermal convection loss to the bottom water should be avoided, and local heating is good for evaporation. Convection above the interface can improve evaporation performance, although it would enhance the thermal convective loss. In addition, evaporation also can be improved by increasing the evaporation area from 2D to 3D structures. Experimental results confirm that the solar evaporation ratio can be improved from 0.795 kg m–2 h–1 to 1.122 kg m–2 h–1 at 1 sun with a 3D interface and thermal insulation between the interface and bottom water. These results can provide a design principle for the solar evaporation system based on thermal management.
