Abstract An electrode with intimate and well‐aligned ZnFe 2 O 4 /TiO composite nanotube arrays is prepared via electrochemical anodization of pure titanium foil in fluorine‐containing ethylene glycol, followed by a novel cathodic electrodeposition method. The deposition promoted the self‐aligned, vertically oriented TiO but minimized at tube entrances. Thus, pore clogging prevented. Environmental scanning electron microscopy, energy‐dispersive X‐ray spectra, high‐resolution transmission...
A ternary Ag/AgBr/TiO(2) nanotube array electrode with enhanced visible-light activity was synthesized by a two-step approach including electrochemical process of anodization and an in situ photoassisted deposition strategy. The dramatically photoelectrocatalytic the composite evaluated via inactivation Escherichia coli under visible light irradiation (λ>420 nm), whose performance complete sterilization much superior to other reference photocatalysts. PL, ESR, radicals trapping studies...
This work focuses on exploring metal–organic frameworks (MOFs) for degradation of gaseous pollutants.
In an effort to develop nanostructured photocatalysts achieve high performance in heterogeneous photocatalysis, a novel composite V2O5/BiVO4/TiO2 photocatalyst was successfully synthesized by using sequentially hydrothermal and adhering method. The structural optical properties of the as-prepared samples were comparatively characterized. formed ternary nanojunctions composed TiO2 nanobelts V2O5/BiVO4 nanorods which self-assembled smaller V2O5 BiVO4 nanoparticles. Compared pure nanorods,...
Abstract Single atom catalysts (SACs) are considered as the emerging for boosting electricity‐driven CO 2 reduction reaction (CRR) and hydrogen evolution (HER). To replace rare expensive noble metal electrocatalysts, developing nonprecious SACs (NPMSACs) with superior electrocatalytic activity stability is of paramount importance achieving high efficiency in CRR HER. Herein, a brief overview recent achievements carbon‐rich NPMSACs both HER provided. The synthesis strategies corresponding...
The ZnO quantum dots (about 3 nm in average size) and the nanorods 80 length 14 width) were synthesized by sol−gel method. They characterized X-ray powder diffraction (XRD), transmission electron microscopy (TEM), UV−vis spectroscopy, photoluminescence (PL) spectroscopy. surface photovoltage (SPV) of nanoparticles was investigated means spectroscopy (SPS) field-induced (FISPS), bands identified. results show that SPV are greatly different for their sizes as a result confinement effect....
A well-aligned ZnFe2O4/TiO2 composite nanotube array (ZnFe2O4/TiO2−NTs) electrode with visible-light activity was successfully prepared using a two-step electrochemical process of anodization and novel cathodic electrodeposition method followed by annealing. The ZnFe2O4 nanoparticles were highly dispersed inside the TiO2−NTs but minimized at tube entrances. structure optical properties TiO2 nanotubes derived composites have been well characterized. displayed strong photo response in visible...
TiO2 nanotube arrays were decorated with Ag/Ag3PO4 nanoparticles through a sequential chemical bath deposition and followed by partial reduction of Ag+ ions in the Ag3PO4 to Ag0 under UV irradiation.

This work aims at the exploration of nanostructured ferroelectric-material-modified semiconductor electrodes for enhanced photo-induced activity. A well-aligned BiFeO3/TiO2-nanotubes (NTs) array with visible-light activity was successfully synthesized on a titanium sheet by combining anodization and an ultrasonic-immersion method followed annealing. The structural optical properties TiO2-NTs composite BiFeO3/TiO2-NTs were comparatively characterized. grown Ti used as electrode exhibited...
Spinel zinc manganese oxide (ZnMn2O4) nanorods were successfully prepared using the previously synthesized α-MnO2 by a hydrothermal method as template.
