Anionic/cationic synergistic action of insulator BaCO3 enhanced the photocatalytic activities of graphitic carbon nitride
Source abstract
Abstract
Abstract The weaker absorption capacity of visible light and higher recombination efficiency of photogenerated electron/hole are the key elements that inhibit photocatalytic activity. In this work, graphitic carbon nitride was first modified via the synergistic action of anionic/cationic of insulator BaCO3, which achieved the superior efficiency of the removal of crystal violet (CV) and tetracycline (TC). The mechanism of insulator optimization g-C3N4 is systematically explained from the perspective of anionic and cationic. Specifically, Ba2+ optimizes the planar torsion of g-C3N4 to facilitate the transmission of electrons, meanwhile CO32− prolongs the migration path of the photogenerated carriers. In addition, a possible photodegradation of CV pathway is proposed based on scavenger experimental, ESR and HPLC-MS. This study provides a novel direction to fully understand the ability of insulators to transfer photogenerated electrons from semiconductors and opens up a new avenue for wastewater treatment based on insulator-semiconductor catalysts.
