Solar steam generation and adsorption, as promising technologies to tackle water pollution, have gained increasing research interest in recent years. In this paper, 3D spherical carbonized platanus fruit with special surface topology and inner interconnected porous structure is used as a superior solar evaporator and an adsorbent for dye removal with easy separation from treated water. The dual‐functional material with single component is prepared by a simply carbonizing biowaste platanus fruit. A high evaporation rate up to 2.00 kg m⁻² h⁻¹ under one sun is achieved by 3D spherical evaporator. 3D evaporator also presents outstanding water evaporation under low light intensity, angle‐independent water evaporation, and long‐term cycling stability. Importantly, high‐capacity dye adsorption and generation of purified water are simultaneously achieved with the assistance of solar‐driven evaporation under one sun. Thus, the monolithic, dual‐functional 3D material with a simple preparation process, low cost, mechanical robustness, and environmental friendliness has great potential for solar steam generation and solar water evaporation‐assisted adsorption. This study proposes a simple route to design 3D solar evaporators with surface topology and innovatively provides a high‐efficiency method for tackling water pollution.

一种低成本3D球形蒸发器，具有独特的表面拓扑和内部结构，用于处理太阳能蒸发辅助的染料废水

太阳能蒸汽的产生和吸附作为解决水污染的有前途的技术，近年来已引起越来越多的研究兴趣。在本文中，具有特殊表面拓扑结构和内部相互连接的多孔结构的3D球形碳化铂金果实被用作高级太阳能蒸发器和吸附剂，用于去除染料并易于与处理后的水中分离。具有单一成分的双功能材料是通过简单地碳化生物废物的桔梗果实而制备的。高达2.00 kg m ^-2 h ^-1的高蒸发速率在3个球面蒸发器的作用下，在一个阳光下就可以实现。3D蒸发器还表现出在低光照强度下出色的水蒸发，独立于角度的水蒸发以及长期的循环稳定性。重要的是，借助太阳驱动的蒸发，在一个太阳下，可以同时实现高容量染料的吸附和纯净水的产生。因此，具有简单制备过程，低成本，机械坚固性和环境友好性的单块，双功能3D材料在太阳能蒸汽产生和太阳能蒸发辅助吸附方面具有巨大的潜力。这项研究提出了一种设计具有表面拓扑结构的3D太阳能蒸发器的简单途径，并创新地提供了一种解决水污染的高效方法。
