Using minimal photothermal material to achieve maximum evaporation rate is extremely important for practical applications of interfacial solar technology. In this work, we found that with the increase in size surfaces, decreased. Both experimental and numerical simulation results confirmed when surface increased, middle portion acted as a "dead zone" little contribution water evaporation. Based on this, was selectively removed, counterintuitively, both vapor output were increased due re-configured enhanced convection above entire surface. As such, work developed an strategy higher vapour while using less material.

Abstract Solar‐powered vapor evaporation (SVG), based on the liquid‐gas phase conversion concept using solar energy, has been given close attention as a promising technology to address global water shortage. At molecular level, molecules escaping from liquid should overcome attraction of surface layer evaporate. For this reason, it is better reduce energy required for by breaking smaller number hydrogen bonds or forming weak ensure efficient and convenient production. Many novel evaporator materials effective activation strategies have proposed stimulate rapid steam production surpass theoretical thermal limit. However, an in‐depth understanding phase/enthalpy change process unclear. In review, summary analyses vaporization enthalpy, general calculations, characterization methods provided. Various mechanisms are also outlined enthalpy in evaporators. Moreover, unsolved issues associated with critically discussed provide direction future research. Meanwhile, significant pioneering developments made SVG highlighted, hoping relatively entire chain more scholars who just stepping into field.

Abstract Improving interfacial solar evaporation performance is crucial for the practical application of this technology in solar‐driven seawater desalination. Lowering enthalpy one most promising and effective strategies to significantly improve rate. In study, a new pathway lower vaporization by introducing heterogeneous interactions between hydrophilic hybrid materials water molecules developed. 2D MoN 1.2 nanosheets are synthesized integrated with rGO form stacked ‐rGO heterostructures massive junction interfaces evaporation. Molecular dynamics simulation confirms that atomic thick simultaneously interact molecules, while remarkably different. These cause an imbalanced state, which easily breaks hydrogen bonds leading dramatically lowered improved rate (2.6 kg m −2 h −1 ). This study provides strategy designing 2D‐2D regulate evaporate clean production.

Abstract Solar steam generation has emerged as an environment‐friendly and promising strategy to overcome the freshwater energy crisis. However, simultaneously attaining satisfied evaporation rate, durability utilization in a single system is challengeable, but crucial practical application. Herein, inspired by carpet weaving technique benefiting from “fiber–yarn–fabric” hierarchical structures, 3D fabric evaporator with vertical hemp‐yarn arrays innovatively constructed, featuring combined structure of multiscale pores tunable spacing between adjacent fibers or yarns, vertically aligned architecture coated superhydrophilic MXene‐sandwiched layer adjustable side height/areas. These structures work cooperatively, surprisingly achieving integrated functions excellent light capture, balanced area vapor escape space, additional adsorption environment salt exchange along micro/macro pores. Consequently, exhibits outstanding rate (3.95 kg m −2 h −1 under one‐sun illumination) extremely high outdoor (47.04 for 8 h), accompanied salt‐resistance (continuous 120 14% brine without accumulation), anti‐oilfouling anti‐bacterial (efficiency over 99.9%) performances. Finally, through rationally assembling multi‐function modules condenser, all‐in‐one “desalination–thermoelectricity–irrigation” platform built, realizing maximum condensation enthalpy.
