Solar energy triggered steam generation has emerged as a green and sustainable strategy that can potentially address the long-standing global freshwater scarcity issue. However, given that there is inadequate light illumination early in the morning or late afternoon or cloudy days, it is continuous steam generation in all weather that is a great challenge for the state-of-the-art solar-driven steam generators. Here, we present an all-weather-available steam generation system, which is capable of harvesting solar energy to continuously generate steam based on the alternative photo-thermal and electro-thermal conversion of crosslinked MXene aerogels (CMAs) in the day time and at night. In virtue of the strong light absorption and excellent electrical conductivity of the CMA, the constructed steam generation system can not only convert sunlight into heat for steam generation on sunny days but persistently achieve heat generation by utilization of electricity in low-light or dark circumstances. Furthermore, the ingenious introduction of solar cells-battery components makes full use of the daytime sunlight to further power the steam generation system for heating up the CMA at night, avoiding extra electrical energy input and loss. This work offers new insights into developing continuous steam generation technologies applicable to day–night alternation and complex environments.

基于MXene的气凝胶基于光热和电热的协同转化，可全天候连续产生蒸汽

太阳能触发的蒸汽产生已经成为一种绿色且可持续的战略，可以潜在地解决长期存在的全球淡水短缺问题。但是，考虑到清晨或午后或阴天的光照不足，对于所有先进的太阳能驱动蒸汽发生器来说，全天候连续产生蒸汽是一个巨大的挑战。在这里，我们介绍了一种全天候可用的蒸汽发生系统，该系统能够在白天和晚上根据交联的MXene气凝胶（CMA）的光热和电热交替转化来收集太阳能以连续产生蒸汽。夜晚。凭借CMA的强光吸收能力和出色的导电性，建成的蒸汽发生系统不仅可以将阳光转化为热能以在晴天产生蒸汽，而且可以在弱光或黑暗的情况下通过利用电力持续实现热量的产生。此外，巧妙地引入了太阳能电池组件，充分利用了白天的阳光，进一步为蒸汽产生系统提供动力，以在晚上加热CMA，避免了额外的电能输入和损耗。这项工作为开发适用于昼夜交替和复杂环境的连续蒸汽发生技术提供了新的见解。巧妙地引入了太阳能电池组件，充分利用了白天的阳光，进一步为蒸汽产生系统提供动力，以在晚上加热CMA，避免了额外的电能输入和损耗。这项工作为开发适用于昼夜交替和复杂环境的连续蒸汽发生技术提供了新的见解。巧妙地引入了太阳能电池组件，充分利用了白天的阳光，进一步为蒸汽产生系统提供动力，以在晚上加热CMA，避免了额外的电能输入和损耗。这项工作为开发适用于昼夜交替和复杂环境的连续蒸汽发生技术提供了新的见解。
