This study presents a low-cost and facile method for preparing a solar steam generator based on PVA/MXene and protonated g-C3N4 coated on natural latex foam (LF). The prepared photothermal evaporator shows excellent light absorption and hydrophilic surface, resulting in a high water evaporation rate and solar steam efficiency. It provides an alternative approach to enhance solar water evaporation performance, with potential applications in drinkable water and industrial wastewater treatment.
Herein, low-cost and facile preparation of solar steam generator based on PVA/MXene and protonated g-C3N4 coated on natural latex foam (LF) was reported. The as-prepared photothermal evaporator demonstrates excellent light absorption of 93% and hydrophilic surface due to PVA/MXene and p-g-C3N4 coating. As a result, the PVA/MXene and p-g-C3N4 delivers a water evaporation rate of 1.85 kg m(-2)h(-1) and solar steam efficiency of 93.5% were achieved under 1 kW cm(-2), and surpassed the most recently reported on MXene and LF-based evaporators. This study provides an alternative approach to enhance solar water evaporation performance and promising for drinkable water and applicable for industrial wastewater treatment.
