Filling foaming agent into stacked layers: Rapid synthesis of graphitic carbon nitride nanosheets decorated with ultrafined MXY (X = O, S) nanoparticles for enhanced photoresponsive abilities

Exfoliating bulk g-C3N4 into 2D nanosheets with high-yield by a foaming agents assisted microwave digestion only requires 5 min. This efficient and eco-friendly method significantly reduces the exfoliating time and can be further utilized to produce ultrafined metal oxides or metal sulfide nanoparticles decorated g-C3N4 nanosheets.119
