Interfacial charge transfer weakens hydrogen bonds between water molecules to accelerate solar water evaporation

“…The reason why IW with weaker hydrogen bonds is the bulk of the water produced by interfacial solar evaporation is that they tend to escape below the boiling point. [21][22][23][24] Highly polar surface rGOFpl foam was designed as an interfacial solar evaporation absorber by loading uorphlogopite (KMg 3 (AlSi 3 O 10 )F 2 ) nanosheets (Fpl nanosheets), which contains numerous highly electronegative F and O atoms onto three-dimensional (3D)-reduced graphene oxide (rGO). rGOFpl foam exhibited an 86.7% increase in the water evaporation rate over conventional rGO foam, reaching up to 1.83 kg m −2 h −1 , which is higher than the most common rGO-based solar absorbers in terms of the actual evaporation utilization area.…”
