主 题：S-scheme heterojunction Red phosphorous BaTiO3 Photocatalytic activity
摘 要：The S-scheme heterojunctions can effectively separate photogenerated electrons and holes,retain their high redox capacity,and provide great prospects for enhancing the photocatalytic activity of the composites in different ***,S-scheme heterojunction photocatalytic materials were rationally designed and prepared by a simple hydrothermal method between narrow-bandgap red phosphorus(HRP)and wide-bandgap BaTiO_(3)(BTO)*** to the effective charge separation and redox ability from the S-scheme mechanism and oxygen vacancies,BTO/HRP exhibited good photoelectrochemical and photocatalytic degradation *** photoreaction tests demonstrated that BTO/HRP had high practicality in the removal of pollutants from wastewater;its photodegradation rate of Rhodamine B reached 3.029×10^(−1) min^(−1) in 12 min;and it could inactivate 1.8×10^(9) CFU/mL of *** in 1 h,with an antibacterial rate of 99.8%.This paper provided a promising photocatalyst for pollutant removal and a new strategy for the fabrication of efficient RP-based photocatalytic materials.
