One-step hydrothermal preparation of Ta-doped ZnO nanorods for improving decolorization efficiency under visible light

Abstract

The Ta doped ZnO nanorods (Ta-ZnO) were synthesized by a hydrothermal method at different temperatures (110, 150, and 170 °C) for the photodegradation of methylene blue (MB) under visible light.

Enhanced photocatalytic performance of ZnO under visible light by co-doping of Ta and C using hydrothermal method

“…34 According to JCPDS standard 00-036-1454, the sharp peaks were attributed to the (100), ( 002), ( 101), ( 102), ( 110), ( 103), ( 200), (112), and (201) lattice planes. Since the TaZ sample was prepared with optimal preparation conditions mentioned in the previous study, 26 the XRD patterns of the TaZ sample displayed analogously to those of the ZnO sample without the peaks of impurities. On the other hand, with the same preparation conditions, out of the presence of major diffraction peaks of the hexagonal wurtzite ZnO structure with a signicant increase in peak intensities, the additional peaks of impurities were presented parallelly.…”

“…In one of the recent publications of our group, the effect of temperature on the preparation of Ta-doped ZnO materials by hydrothermal for MB photodegradation was examined. 26 The samples prepared at 150 °C (TaZ150) displayed the most redshift of the optical absorption edge, with the bandgap narrowed from 3.07 eV (ZnO) to 2.92 eV, enabling visible-light absorbability. TaZ150 also exhibited superior performance in reducing the electron/hole recombination rate and improving the MB degradation efficiency as compared to TaZ and ZnO samples.…”

ZnO based 0–3D diverse nano-architectures, films and coatings for biomedical applications

“…25 Additionally, the direct bandgap of 3.37 eV allows ZnO to effectively absorb UV light which extends up to the visible region through surface modifications and engineering nano-architectures. [26][27][28] An electronic device can effectively be employed for a variety of sensing purposes due to both features, i.e., n-type conductivity and UV-sensitive bandgap, if it can be constructed utilizing suitable nano-and microstructures. For example, 1D ZNSs show piezoelectric characteristics because of their non-centrosymmetric crystal structure.…”

Zinc Oxide Nanoparticles as Efficient Heterogeneous Catalyst for Synthesis of Bio‐active Heterocyclic Compounds

“…[56][57][58][59][60] Nanocatalysts are of great importance in the context of environmentally conscious science, and in particular for catalysis, due to their nanocatalysts' effectiveness [61][62][63][64][65][66][67] as a coating on silicate, aluminium oxide, titanium dioxide, fiberglass, ceramics, and activated carbon has been the subject of several research during the past decade. [46,[68][69][70][71][72][73][74][75] Nanocatalysts are now widely used to produce heterocyclic compounds. [76] Herein, we discuss the most recent (2012 to present) nano-catalytic synthesis of highly substituted heterocycles.…”
