Flatband λ-Ti3O5 boosts solar evaporation

Interfacial solar evaporation is regarded as a promising strategy for water purification, and materials with high evaporation performance have been continually explored. Recently in Nature, Yang et al. reported that flatband λ-Ti3O5-integrated hydrogel-based evaporators achieve an ultrahigh water evaporation rate of 6.09 kg m−2 h−1 under 1 sun irradiation.
