Construction of carbon-doped mesoporous g-C3N4 catalytic nanoreactor via bubble template method for visible-light photocatalysis

Morphological control of photocatalysts is an important way to improve photocatalytic activity. Herein, we design a carbon-doped mesoporous g-C3N4 nanoreactor by combining the self-assembly method of supramolecular precursors with the bubble template method. The mesoporous structure can increase the utilization rate of light absorption. Furthermore, the C atoms replace the position of bridging N atoms may generate delocalized large pi bonds, both of which can facilitate photocatalysis. This nanoreactor coupled with larger specific surface area and faster electronic transmission efficiency shows an outstanding performance in photocatalytic RhB degradation (97%, 15 min) and reducing CO2 into CO (60.82 mu mol/g, 5h). The C-doped mesoporous g-C3N4 nanoreactor would provide some practical reference for environmental improvements and clean energy production.
