Enhancing solar steam generation using a highly thermally conductive evaporator support

Science Bulletin, Год журнала: 2021, Номер 66(24), С. 2479 - 2488

Опубликована: Сен. 23, 2021

Interfacial solar steam generation is an efficient water evaporation technology which has promising applications in desalination, sterilization, purification and treatment. A common component of evaporator design a thermal-insulation support placed between the photothermal surface bulk water. This configuration, 2-dimensional (2D) systems, minimizes heat loss from to water, thus localizing on for evaporation. subsequently directly adopted 3-dimensional (3D) evaporators without any consideration if it appropriate. However, unlike 2D evaporators, 3D can also harvest additional energy (other than light) air enhance rate. In this scenario, use thermal insulator not proper since will hinder extraction Here, traditional configuration was completely redesigned by using highly thermally conductive material, instead insulator, connect surfaces Much higher rates were achieved strategy, owing rapid transfer surfaces. Indoor outdoor tests both confirmed that performance could be significantly improved substituting with support. These findings redirect future evaporators.

More from less: improving solar steam generation by selectively removing a portion of evaporation surface

Science Bulletin, Год журнала: 2022, Номер 67(15), С. 1572 - 1580

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‐driven interfacial evaporation is an important approach for solving the issue of freshwater scarcity. However, practical application solar steam generation hindered by high fabrication cost and environmental concerns regarding petroleum‐based materials. Herein, lignocellulose (cellulose‐lignin composite) hydrogel (LCG) lignin‐derived carbon (LC) are used as substrate photothermal material, respectively, to construct a fully lignocellulose‐based double‐layered (LC@LCG) evaporator. Results indicate that LC has ultrahigh specific surface area full‐spectrum absorption 98%. The presence lignin can improve hydrophilicity maintain capillary channels hydrogel, which tunes water into intermediate state reduces vaporization enthalpy water. Moreover, it ensures transport rate in hydrogel.
