Abstract
A novel ternary Ag3PO4/Co3(PO4)2/g-C3N4 (APO/CPO/CN) heterostructure photocatalyst was successfully synthesized via a simple precipitation method for photocatalytic degradation of tetracycline (TC) under visible light irradiation. The experimental result reveals that the ternary APO/CPO/CN heterojunction showed enhanced photocatalytic performance compared with single semiconductor CPO and CN, binary composite CPO/CN. And APO/CPO/CN-15 % composite exhibits highest photocatalytic degradation efficiency, which can degrade TC around 88 % under visible light within 120 min. The enhanced photocatalytic performance is due to the synergy effects between CPO, CN and APO with the aid of following Z-scheme and Type II heterojunction dual pathways for effective separation of photogenerated charges. This work provides a new approach in the rational design of ternary heterojunction photocatalyst with multilevel electron transfer for environmental decontamination.Entities:
