Abstract

Environmental pollution and bacterial infections are serious problems that mankind has been facing. The simultaneous removal of pollutants and bacteria has attracted widespread attention. Herein, Hydroxyapatite (HAp)/TiO₂ photocatalysts were prepared with anatase TiO₂ exposing {101} and {001} facets as supports. HAp/TiO₂{101} exhibited excellent enhancement in photocatalytic degradation compared to HAp/TiO₂{001} and the pristine TiO₂ nanocrystals. The optimum HAp/TiO₂{101} photocatalyst displayed 77% degradation efficiency of tetracycline (TC) under 300 W xenon lamp within 60 min, as well as excellent stability and reproducibility. The inhibition rates for Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) are up to 98.3% and 97.2%, respectively. Moreover, it is biocompatible and has a remarkable therapeutic effect on wounds infected with S. aureus. The possible photocatalytic mechanism of HAp/TiO₂{101} was proposed and proved by EPR results. It has been demonstrated that ·O₂⁻, h⁺ as well as their corresponding reactive oxygen species (ROS) play a dominant role in the processes of TC degradation and antimicrobial actions. This work represents the first systematic exploration regarding the capability of HAp/TiO₂{101} which exhibits facet-dependent properties in the photocatalytic degradation, antimicrobial activities, as well as in the treatment of wound infections. It vividly demonstrates its prospective applications in the fields of environmental protection, life, and health.

期刊介绍： Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis. The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
