AgBr Nanoparticles in Situ Growth on 2D MoS2 Nanosheets for Rapid Bacteria-Killing and Photodisinfection
Source abstract
Abstract
In this study, a multifunctional hybrid coating composed of AgBr nanoparticles (AgBrNPs) and two-dimensional molybdenum sulfide (MoS2) nanosheets (AgBr@MoS2) was constructed on Ti implant materials using an in situ growth method for the first time. With 660 nm light and visible light irradiation, the electrons were rapidly excited from the valence band of MoS2 to its conduction band, at the same time, AgBrNPs was used as a photoelectric receiver, which exhibited an enhanced photocatalytic activity due to the rapid transfer of photoelectrons from MoS2 nanosheets to AgBrNPs and the suppression of the recombination of electron-hole pairs. This contributed to the rapid production of reactive oxygen species under 660 nm light irradiation, thus the AgBr@MoS2 system killed bacteria and degraded organic matter quickly and efficiently in a short time. Meanwhile, the AgBr@MoS2 system showed excellent stability due to the strong covalent binding between S and Ag in the system, thus preventing AgBrNPs from being reduced to metal Ag.
