“…Compared to precious metal elements, the Al element is a good candidate for plasmonic material due to its abundance on earth and low costs. Recently, electron beam evaporation was employed to fabricate different material nanoparticles [ 20 , 21 , 22 ], which possesses advantages of compactness, uniformity and simple working conditions. Thus, a metal–semiconductor–metal (MSM) structured photodetectors of ZnO NRs decorated with Al NPs were fabricated by the hydrothermal method and electron beam evaporation, and the effect of Al NPs on the photoresponse performance of the ZnO NRs photodetectors was investigated.…”

In this work, localized surface plasmon resonance (LSPR) mediated by aluminum nanoparticles (Al NPs) was investigated to enhance the ultraviolet (UV) response of the zinc oxide nanorods (ZnO NRs) grown by the hydrothermal method. The ZnO NRs were characterized by scanning electron microscope, energy dispersive spectroscopy, X-ray diffractometer, Raman spectrometer, ultraviolet-visible spectrophotometer and fluorescence spectrometer. The results show that the morphology and crystalline structure of the ZnO NRs could not be changed before and after decoration with Al NPs, but the absorption rates in the UV range and the photoluminescence (PL) properties were improved. The photo-to-dark current ratio of ZnO NRs with Al NPs was about 447 for 325 nm UV light (5 mW/cm2) at 3.0 V bias, with the sensitivity increasing from 9.5 to 47.8, and the responsivity increasing from 53 to 267 mA/W.

“…26 The zirconium oxide (ZrO 2 ) nanoparticles has been investigated extensively for its good physiochemical properties. [27][28][29] However, using nascent ZrO 2 directly in heavy metal extraction has a number of drawbacks, including limited adsorption capacity and a tendency to agglomerate, resulting in poor dispersion. 29 In aqueous conditions, interparticle interaction causes ZrO 2 to stack, and reducing its adsorption ability.…”

Titania photocatalyst is widely employed in the removal of organic pollutants from water streams. However, TiO2 suffers from agglomeration and is mostly active under UV light resulting in low system efficiency. In this study, we prepared sol–gel TiO2 immobilized on beta (BEA) and silicalite zeolites for the photocatalytic degradation of tetracycline antibiotics under visible light. Ferric ions were incorporated into the supported Titania photocatalyst via ion exchange method to enhance its visible light absorption. The deposition of the Titania over BEA zeolite greatly enhanced its adsorption efficiency (from 5.6% to 24%) and surface area (from 90 to 305.9 m2/g) while silicalite support only slightly affected the adsorption of Titania. The scanning electron microscope (SEM) characterization of the photocatalysts indicated that the zeolite structure was conserved after modification and the UV–VIS DRS characterization confirmed the enhancement of visible light absorption. The TiO2/Fe‐Beta was able to degrade 100% of tetracycline (TC) in solution under blue light after 90 min compared to only 30% by TiO2/Fe‐silicalite and 28% by TiO2. When the weight percentage of TiO2 in the TiO2/Fe‐silicalite photocatalyst increased from 20% to 60%, its efficiency increased from 87% to 99% after 300 min. Similar results were also obtained under white light, where the TiO2/Fe‐Beta achieved the highest efficiency (81.5%) as compared to TiO2/Fe‐silicalite (66.6%) and TiO2 (44.7%). We attribute this enhanced performance of TiO2/Fe‐Beta to enhanced adsorption capacity due to BEA immobilization and improved visible light absorption.
