The aerogels with low thermal conductivity and cross-linked 3D networks can be easily integrated with functional materials to maximize their functionalities, realizing diverse applications such as photothermal seawater desalination and photocatalytic uranium extraction. SpC-conjugated porous polymers (spC-CPPs) with robust and conjugated CC linkages are ideal photosensitizers for these applications, owing to their exceptional semiconducting properties as well as chemical stability. However, the limited processability and collectability of as-synthesized spC-CPP powders impede their extended applications. Herein, we report the preparation of robust spC-CPP (DHA-TMT and DBD-TMT) based aerogels surface-initiated aldol polycondensation (SI-AP). The fully conjugated CC skeletons and electron-donating groups (-OH) endow the spC-CPP aerogels with excellent photothermal conversion efficiency (95.6%) and strong affinity for uranium adsorption. In particular, the DHA-TMT aerogel with hydrophilic porous channel exhibits a superb evaporation performance achieving ∼1.55 kg m h under AM 1.5 G while the fast mass transfer caused by photothermal conversion increases the uranium extraction capacity up to 1200 mg m in simulated seawater. Moreover, the spC-CPP aerogels demonstrate high stability under strong acid, base and brine solutions. This work shows a strategy for the preparation of uniform and high stability spC-CPP-based aerogels to simultaneously enhance their photothermal and photocatalytic performance.
