Interfacial water evaporation through solar heating with photothermal materials is a promising strategy for seawater desalination and wastewater purification. Tightly packed 2D membranes with high reflection losses and limited vapor escape channels result in a low evaporation rate. In this work, 3D MXene architecture was fabricated by dropping the delaminated Ti 3 C 2 ([Formula: see text]-Ti 3 C 2 ) nanosheets onto the carbonized melamine foam (CMF) framework. Owing to the macroporous 3D architecture, more effective broadband solar absorption and vapor escaping were achieved. As a result, the 3D CMF@[Formula: see text]-Ti 3 C 2 -based evaporator delivers a water evaporation rate of 1.60[Formula: see text]kg/m 2 [Formula: see text][Formula: see text][Formula: see text]h with a solar-to-vapor conversion efficiency of up to 84.6%.
