Introduction

Herein, we discussed different beneficial characteristics of aerogels in the solar steam generation process, including high porosity, low cost, versatility, environmental friendliness, and self-floating, in detail. This study developed a new strategy to create environmentally friendly 3D cellulose aerogels, referred to as black cellulose aerogel (BCA) and black cellulose aerogel with beeswax (BCAW). These aerogels were produced using a simple, fast freeze-drying method with eco-friendly precursors. The unique. Driven by renewable energy, solar-thermal technology holds promising potential for effective freshwater production with a reduced carbon footprint. In this technology, solar energy is localized at the air–water interface of the solar-thermal conversion material. Despite many technical advantages. Desalination of seawater is a possible solution, and one approach involves porous materials absorbing water that evaporates when heated by solar energy. The problem with most existing solar-powered evaporators is that they are difficult to scale up for larger populations. Performance decreases with. Solar-driven interfacial water evaporation technology has garnered significant attention due to its considerable potential in seawater desalination and wastewater treatment. Cellulose-based aerogel (CBA) has become a highly promising photothermal evaporation material due to its excellent. A new type of aerogel developed by researchers at Hong Kong Polytechnic University could significantly improve the process of desalinating seawater, making it more efficient and scalable. Traditional solar-powered evaporators often struggle to perform effectively on a larger scale due to structural.
