Superimposed surface plasma resonance effect enhanced the near-infrared photocatalytic activity of Au@Bi 2WO 6 coating for rapid bacterial killing. JOURNAL OF HAZARDOUS MATERIALS 2019; 380:120818. [PMID: 31310928 DOI: 10.1016/j.jhazmat.2019.120818] [Citation(s) in RCA: 52] [Impact Index Per Article: 10.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/17/2019] [Revised: 06/22/2019] [Accepted: 06/24/2019] [Indexed: 05/12/2023]
Abstract
Bacterial infection has become a serious public health challenge because the misuse of antibiotics worldwide has induced bacterial resistance and superbug occurrences, that is, no suitable antibiotics are available. Herein, we design a new infrared photocatalytic system on titanium (Ti) substrates, and it consists of gold (Au) nanorod-decorated bismuth tungstate (Bi2WO6) nanosheets (Au@Bi2WO6). The surface plasmon resonance (SPR) effect induced by near infrared (NIR) facilitates partial photo-induced electron transfer between Au and Bi2WO6, resulting in accelerated charge transmission and consequently hindering electron-hole recombination, which imparts high photocatalytic property to the coating. In addition, the superimposed SPR from both Au and Bi2WO6 can improve the photothermal effect of Au@Bi2WO6. As a result, when irradiated with 808 nm NIR for 15 min, this hybrid coating exhibits a superior antibacterial efficiency of 99.96% and 99.62% against Escherichia coli and Staphylococcus aureus, respectively, due to the synergistic effects of high yield of radical oxygen species and hyperthermia; this efficiency cannot be achieved by either Au-Ti or Bi2WO6-Ti alone. This platform exhibits a great potential for noninvasive disinfection without using antibiotics.

Abstract
Efficient photogenerated charge separation is needed for potential solar energy conversion and storage. Herein, we present the preparation and characterization of an optically active anthracence-based molecule 4,4′-(anthracene-2,6-diylbis(azanediyl))bis(4-oxobutanoic acid) (ABDA), whose coupling with TiO2 has been proven useful in the pursuit of enhanced photoelectrochemical (PEC) performance. Ultraviolet-visible absorption spectroscopy and PEC measurements indicated that the ABDA/TiO2 composite has extended the light absorption of TiO2 to the visible region and efficiently increased the charge separation. The photocurrent of ABDA/TiO2 is 1.8 times higher than that of pristine TiO2. This study has provided a method for the development of functionalized TiO2 with enhanced PEC behaviour for energy conversion applications.
