Published: Jan. 15, 2025

Solar-driven interfacial evaporation technologies use solar energy to heat materials that drive water evaporation. These are versatile and do not require electricity, which enables their potential application across the food, nexus. In this Review, we assess of solar-driven in clean-water production, wastewater treatment, resource recovery. Interfacial can produce up 5.3 l m–2 h−1 drinking using sunlight as source. Systems designed for food production coastal regions desalinate irrigate crops or wash contaminated soils. Technologies being developed simultaneously both clean through have reached 204 W electricity 2.5 h–1 separate systems. Other approaches combinations could potentially full spectrum generate multiple products (such water, heating cooling, and/or fuels). future, aid provision low-resource rural settings lack reliable access these essentials, but systems must first undergo rigorous, scaled-up field testing understand performance, stability competitiveness.

Nano Letters, Journal Year: 2024, Volume and Issue: 24(34), P. 10583 - 10591

Published: Aug. 13, 2024

As global freshwater shortages worsen, solar steam generation (SSG) emerges as a promising, eco-friendly, and cost-effective solution for water purification. However, widespread SSG implementation requires efficient photothermal materials evaporators that integrate enhanced light-to-heat conversion, rapid transportation, optimal thermal management. This study investigates using nonoxidized graphene flakes (NOGF) with negligible defects capable of absorbing over 98% sunlight. By combining NOGF cellulose nanofibers (CNF) through bidirectional freeze casting, we created vertically radially aligned evaporator. The hybrid aerogel exhibited exceptional absorption, solar-to-thermal improved surface wettability. Inspired by tree structures, our design ensures supply while minimizing heat loss. With low content (∼10.0%), the NOGF/CNF achieves rate 2.39 kg m
