In-Situ Growth of Au on KTaO3 Sub-Micron Cubes via Wet Chemical Approach for Enhanced Photodegradation of p-Nitrophenol

KTaO3/Au hetero-nanostructures were synthesized by in-situ reduction of HAuCl4 on the surface of hydrothermally-grown KTaO3 sub-micron cubes. The concentration of Au source was found to be a critical factor in controlling the hetero-nucleation of Au nanoparticles on the surface of KTaO3 sub-micron cubes. Loading of Au particles on KTaO3 nanocrystals enriched KTaO3 additional UV-vis absorption in the visible light region. Both KTaO3 and KTaO3/Au nanocrystals were shown to be active in the photo-degradation of p-nitrophenol, while the loading of Au on KTaO3 clearly improved the photo-degradation efficiency of p-nitrophenol compared to that on bare KTaO3 nanocrystals, probably due to the improved light absorption and charge separation.

Background and aims: Polystyrene microplates are generally used to specify the absorption in the visible light region of the spectrum. However, they are capable of absorption in the ultraviolet (UV) range of the spectrum while they are not suitable for UV spectroscopy analysis. This study aimed to compare polystyrene and cycloolefin microplates for their background absorbance characteristics in the UV/ VIS region of the spectrum. Methods: Background absorbance of the mentioned microplates was measured using two different spectrophotometers and four various samples. Results: The analysis of our results verified the advantage of applying cycloolefin microplate over polystyrene one for absorbance measurements in the UV range of the spectrum. Conclusion: In general, suitable microplate selection is a critical factor in absorbance measurements, especially in the UV portion of the spectrum.

Pollutants Removal

The coexistence of pollutants presents a great challenge to the implementation of photocatalysts. In this work, a novel MIL-101(Fe)/TiO2 composite prepared by in situ growth of MIL-101(Fe) on TiO2 was developed for the synergetic oxidation of MC-LR and Cr(VI) reduction. The heterojunction material shows elevated photocatalytic behavior under ultraviolet compared with the unary pollutant system. Furthermore, quenching experiments and electron spin resonance confirm that the enhanced photodegradation behavior is related to the synergistic effect between the photocatalytic reduction and oxidation process, in which MC-LR consumes the holes and Cr(VI) captures electrons, followed by efficient charge separation through the conventional double-transfer mechanism between MIL-101(Fe) and TiO2. This investigation provides a deeper understanding of the construction of MOFs/semiconductor heterojunctions for the pollutants removal in multi-component contaminants system.
