A Facile Microwave-Promoted Formation of Highly Photoresponsive Au-Decorated TiO Nanorods for the Enhanced Photo-Degradation of Methylene Blue.

The integration of noble metal nanoparticles (NPs) effectively modifies the electronic properties of semiconductor photocatalysts, leading to improved charge separation and enhanced photocatalytic performance. TiO nanorods decorated with Au NPs were successfully synthesized using a cost-effective, rapid microwave-assisted method in HO and HF media for methylene blue (MB) degradation under visible light illumination. X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), N2 physisorption, and UV-vis spectroscopy were employed to characterize the structures, morphologies, compositions, and photoelectronic properties of the as-synthesized materials.

Effect of Morphology Modification of BiFeO on Photocatalytic Efficacy of P-g-CN/BiFeO Composites.

This current study assessed the impacts of morphology adjustment of perovskite BiFeO (BFO) on the construction and photocatalytic activity of P-infused g-CN/U-BiFeO (U-BFO/PCN) heterostructured composite photocatalysts. Favorable formation of U-BFO/PCN composites was attained via urea-aided morphology-controlled hydrothermal synthesis of BFO followed by solvosonication-mediated fusion with already synthesized P-g-CN to form U-BFO/PCN composites. The prepared bare and composite photocatalysts' morphological, textural, structural, optical, and photocatalytic performance were meticulously examined through various analytical characterization techniques and photodegradation of aqueous rhodamine B (RhB).

Construction of Pt@BiFeO Xerogel-Supported O-g-CN Heterojunction System for Enhanced Visible-Light Activity towards Photocatalytic Degradation of Rhodamine B.

Synthetic organic pigments from the direct discharge of textile effluents are considered as colossal global concern and attract the attention of scholars. The efficient construction of heterojunction systems involving precious metal co-catalysis is an effective strategy for obtaining highly efficient photocatalytic materials. Herein, we report the construction of a Pt-doped BiFeO/O-g-CN (Pt@BFO/O-CN) S-scheme heterojunction system for photocatalytic degradation of aqueous rhodamine B (RhB) under visible-light irradiation.

A Modified Sol-Gel Synthesis of Anatase {001}-TiO/Au Hybrid Nanocomposites for Enhanced Photodegradation of Organic Contaminants.

A sol-gel synthesis technique was employed for the preparation of anatase phase {001}-TiO/Au hybrid nanocomposites (NCs). The scalable, schematic, and cost-efficient method was successfully modified using HF and NHOH capping agents. The photocatalytic activity of the as-synthesized {001}-TiO/Au NCs were tested over 2-cycle degradation of methylene blue (MB) dye and pharmaceutical active compounds (PhACs) of ibuprofen and naproxen under direct sunlight illumination at 35 °C and 44,000 lx.
