“…Associated with the excellent band matching of Ag 3 PO 4 and ZnO, the integration of Ag 3 PO 4 and ZnO has exhibited superior photocatalytic activity for organic pollutant degradation under visible‐light illumination, but scarce study regarding the antibacterial performance of Ag 3 PO 4 /ZnO have been examined. In this study, we present a facile reflux method for the synthesis of novel core/shell/shell SiO 2 /ZnO/Ag 3 PO 4 nanoparticles (SZA‐NPs) by sequential deposition of ZnO and Ag 3 PO 4 on SiO 2 spheres.…”

Novel core/shell/shell SiO2/ZnO/Ag3PO4 nanoparticles (SZA‐NPs) were prepared through a facile reflux method involving sequential deposition of ZnO and Ag3PO4 to SiO2 spheres. The obtained SZA‐NPs were systematically characterized and used as the dual‐functional antibacterial agents for disinfection. Under visible‐light irradiation, the SZA‐NPs exhibit enhanced antibacterial activity for of Escherichia coli DH5α (E. coli) compared to that of Ag3PO4 or SiO2/ZnO in liquid phase and on agar plates. Quantitative analysis of Ag+ release from SZA‐NPs confirms the minor contribution of released silver ions to the antibacterial efficiency. On the other hand, chemical scavengers and photoluminescence studies suggest that radical oxygen species (ROS) also make major contribution to E. coli cell death. The enhanced antibacterial activity of the SZA‐NPs under visible‐light irradiation can be attributed to the synergistic effect of released silver ions and ROS generated from the excellent band matching between Ag3PO4 and ZnO. This work paves a new way for future design of highly efficient visible‐light induced antibacterial agents.

We exploit the utilization of two-dimensional (2D) molybdenum oxide nanoflakes as a co-catalyst for ZnO nanorods (NRs) to enhance their photocatalytic performance. The 2D nanoflakes of orthorhombic α-MoO3 were synthesized through a sonication-aided exfoliation technique. The 2D MoO3 nanoflakes can be further converted to substoichiometric quasi-metallic MoO3-x by using UV irradiation. Subsequently, 1D-2D MoO3 /ZnO NR and MoO3-x /ZnO NR composite photocatalysts have been successfully synthesized. The photocatalytic performances of the novel nanosystems in the decomposition of methylene blue are studied by using UV- and visible-illumination setup. The incorporated 2D nanoflakes show a positive influence on the photocatalytic activity of the ZnO. The obtained rate constant values follow the order of pristine ZnO NR

In this work, carbon nanospheres (CNSs) were prepared with glucose through a hydrothermal synthesis method. Subsequently, a cetyltrimethylammonium bromide (CTAB) bilayer was used to modify the surface of the as-prepared CNSs (denoted as CTAB-CNSs). Interestingly, it was found that CTAB-CNSs could significantly amplify chemiluminescence (CL) emissions from some reactive oxygen species systems, including the Co(II)-H 2 O 2 -OH À system, ClO À system and ONOO À system. The CL intensity was proportional to the concentration of H 2 O 2 in the Co(II)-H 2 O 2 -OH À system in a linear range of 5-1000 mM with a limit of detection of 2.6 mM (S/N ¼ 3). The enhancement mechanism of CTAB-CNSamplified CL from the Co(II)-H 2 O 2 -OH À system was investigated using the fluorescence spectra, CL spectrum, scavengers of reactive oxygen species, and UV-vis absorption spectra. The results indicated that the CTAB bilayer on the surface of CNSs could form a particular micelle microenvironment, facilitating the reaction between reactive intermediates and CNSs. Finally, this method has been successfully used to detect H 2 O 2 in river water and lake water samples, and the recoveries were from 96 to 110%. The relative standard deviation (RSD) for nine repeated measurements was less than 5%. 010 64411957; Tel: +86 010 64411957 † Electronic supplementary information (ESI) available: Effect of the preparation time of CNSs on the CL intensity; TEM image of CNSs; FTIR spectrum of the as-prepared CTAB-CNSs and zeta potential measurements of CTAB-CNSs, CTAB and CNSs; effect of NaOH on the CL intensity; effect of CNSs modied with CTAB, TTAB, SDS and Triton X-100 on CL intensity; CL intensity of the ClO À -H 2 O 2 system and the ONOO À system in the presence of CTAB-CNSs; absorbance spectra of NBT in the absence or presence of the CTAB-CNS-Co(II)-H 2 O 2 -OH À system; tolerance limit of various coexisting substances on the determination of 50 mM H 2 O 2 ; effects of radical scavengers on the CTAB-CNS-Co(II)-H 2 O 2 -OH À system.
