Solar steaming has emerged as a promising green technology that can address the global issue of scarcity of clean water. However, developing high‐performance, cost‐effective, and manufacturable solar‐steaming materials, and portable solar steaming‐collection systems for individuals remains a great challenge. Here, a one‐step, low‐cost, and mass‐producible synthesis of polypyrrole (PPy) origami‐based photothermal materials, and an original portable low‐pressure controlled solar steaming‐collection unisystem, offering synergetic high rates in both water evaporation and steam collection, are reported. Due to enhanced areas for vapor dissipation, the PPy origami improves the water evaporation rate by at least 71% to 2.12 kg m−2 h−1 from that of a planar structure and exhibits a solar–thermal energy conversion efficiency of 91.5% under 1 Sun. When further controlling the pressure to ≈0.17 atm in the steaming‐collection unisystem, the water collection rate improves by up to 52% systematically and dramatically. Although partial energy is utilized toward obtaining low‐pressure, evaluations show that the overall energy efficiency is improved remarkably in the low‐pressure system compared to that in ambient pressure. Furthermore, the device demonstrates effective decontamination of heavy metals, bacteria, and desalination. This work can inspire new paradigms toward developing high‐performance solar steaming technologies for individuals and households.

A solar‐driven interface steam generator (SISG) has potential applications in saline water desalination and polluted water purification. A shape‐ and size‐controlled, low‐cost, eco‐friendly solar‐absorber material is urgently desired for practical applications of SISGs. Herein, a facile, sustainable, and scalable approach is proposed to produce tailored SISGs with controlled macromorphology derived from flour via “dough figurine” technology originating from the China Han Dynasty. Three kinds of self‐floated flour‐based absorbers, i.e., near‐cylindrical (integrated), near‐spherical (loose packing), and powdery (dense packing) absorber used as SISGs, are discussed. More importantly, it is found that the macromorphology significantly influences water transport and interfacial thermal management of SISGs; thus the integrated absorber has an obvious advantage over the other two absorbers, which possesses a high evaporation efficiency of 71.9% at normal solar illumination. The proposed “dough figurine” technology breaks the limitations of the inherent geometry of reported biomass‐based SISGs, which provides an important guidance for SISG use in remote and impoverished areas.

Water shortage and the energy crisis are two major global challenges in this century. The solution for water crisis should be based on a sustainable energy source. Solar‐inspired water purification is an efficient and green technology for tackling the water challenge using abundant and clean solar energy through photothermal evaporation‐induced water production, photoinduced antimicrobial treatment, and photocatalytic degradation of organic contaminants. 2D nanomaterials draw significant attention for their use these three water‐purification methods because of their large surface area, broadband and strong absorption in the solar spectral range, and efficient photothermal and photocatalytic transformation. Herein, the recent development of 2D nanomaterials applied in photothermal evaporation, photoinduced antimicrobial treatment, and photocatalytic capability is comprehensively overviewed. Various strategies in enhancing the light‐absorption and light‐conversion efficiency for different 2D nanomaterials are presented. The challenges and perspectives of these 2D nanomaterials are further discussed for practical water purification. This Review highlights these green energy–driven water‐purification methods based on emerging 2D materials.
