Global energy and environmental problems are becoming increasingly prominent, and the shortage of freshwater resources has been plaguing many countries and regions in the world. Solar steam generation (SSG) has emerged as a green, low‐cost and efficient strategy for freshwater production, which has attracted enormous attention in recent years. Furthermore, various photothermal materials and structural designs for the preparation of efficient SSG systems have been widely reported. Among them, metal‐based photothermal materials are abundant, and the exploration on metal‐based SSG systems is one of the important research directions. In this review, the basic concepts and design objectives of current metal‐based SSG systems are first introduced, as well as advances in the recent development of metal‐based photothermal materials, including photothermal mechanisms, and preparation methods. The evaluation criteria of the SSG system are further described. Then the development of metal‐based SSG systems is summarized in terms of structural design, functional modules (light absorption, thermal management, water transport, salt rejection, etc.), and potential applications (wastewater treatment, sterilization and other fields). Finally, the main challenges and future prospects of metal‐based SSG systems in basic research and practical applications are emphasized.

Solar water evaporation is an efficient and sustainable technology. To reduce energy consumption and improve cost efficiency, the surface modification of wood sponge by polypyrrole-glutathione (PGWS) was achieved using an in-situ synthetic method. The PGWS exhibits excellent adsorption efficiency for Hg(II) ions with adsorption capacity of 330.8 mg g À 1 at 25 °C. Following Hg(II) absorption, the PGWS could be upcycled for solar steam generation. A stackable device was constructed by placing two wood sponges under a Hg(II) saturated PGWS [PGWS-Hg(II)], this system exhibited the highest water evaporation rate of 2.14 kg m À 2 h À 1 under 1 kW m À 2 . Moreover, collecting paper was inserted between the stacked PGWS-Hg(II) and wood sponge for the collection of salts. As such salt can be successfully collected from simulated fertilizer plant effluent and then used as a nutrient for growing plants using a hydroponic system. The facile design of stackable evaporation provides an opportunity for wastewater utilization by harvesting solar energy.
