Exfoliated\nPorous Carbon Nitride by Simultaneous Oxidation-Corrosion\nfor Photocatalytic H<sub>2</sub>O<sub>2</sub> Production and Organic\nDegradation

Graphitic carbon nitride (g-C<sub>3</sub>N<sub>4</sub>) is a fascinating\nmaterial with potential applications in photocatalysis due to its\ngood chemical stability, high thermal stability, and relative ease\nof synthesis. In this work, ultrathin g-C<sub>3</sub>N<sub>4</sub> is constructed using a hybridized method, which combines the advantages\nof thermal and liquid-phase stripping methods. This sample can improve\nperformance in degrading organic pollutants several times, and the\nhighest enhancement efficiency occurs in an alkaline environment.\nIn addition, photocatalytic production of hydrogen peroxide can be\nincreased to 2.6 times that of the bulk sample. These improved properties\nare due to the increase in specific surface area, the generation of\nfree radicals, and adsorption capacity. This work presents a one-step\nexfoliation method for bulk g-C<sub>3</sub>N<sub>4</sub> for more\nsurface-active sites and strong redox capacity.
