Опубликована: Июль 4, 2022

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.
