“…The concentrations of Pd attached at the surface determined were estimated by XPS as 0. The band gap of the semiconductor materials can be determined by analyzing their optical absorption spectra using Tauc plots representing (αhυ) 2 versus hυ and then doing the linear extrapolation of (αhυ) 2 to zero value of hυ (where α is absorption coefficient, hυ is photon energy, h is Planck's constant and υ is the frequency of photon) (Figure S4, Supplementary Material) [26]. The estimated band gap (Eg) values were tabulated (Table 1).…”

TiO2–Zeolite Metal Composites for Photocatalytic Degradation of Organic Pollutants in Water

Immobilization of photocatalysts in porous materials is an approach to significantly minimize the hazards of manipulation and recovery of nanoparticles. Inorganic materials, such as zeolites, are proposed as promising materials for photocatalyst immobilization mainly due to their photochemical stability. In this work, a green synthesis method is proposed to combine TiO2-based photocatalysts with commercial ZY zeolite. Moreover, a preliminary analysis of their performance as photocatalysts for the abatement of organic pollutants in waters was performed. Our results show that the physical mixture of TiO2 and zeolite maintains photocatalytic activity. Meanwhile, composites fabricated by doping TiO2–zeolite Y materials with silver and palladium nanoparticles do not contribute to improving the photocatalytic activity beyond that of TiO2.

“…The use of catalysts for the degradation of acetaminophen occupies an important place in these processes and offers advantages by chemically transforming the organic structure. Examples of these processes are those developed with Ag-Ag 2 O assisted by microwaves (Jannatun and Ufana, 2020) or with co-doped bismuth and Cu catalysts under visible irradiation (Abbas et al, 2022). Silver nanoparticles and ZnO and CuO nanorods (Al-Gharibi et al, 2021;Aminzadeh et al, 2021) are just some of the recent developments, although these studies present promising results.…”

The degradation of acetaminophen (ACET) was studied with TiO2-Ag catalysts, whose predominant crystalline phase was anatase, synthesized by the sol–gel method and doped by photo-deposition under UV radiation with silver particles. The catalyst was characterized by energy dispersive X-ray fluorescence (EDXRF) and X-ray diffraction (DRX). The acetaminophen degradation was determined by high-performance liquid chromatography (HPLC) and total organic carbon (TOC). The reaction behavior was studied under the Langmuir–Hinshelwood (LH-HW) equation and in a TOC-based model. With the experimental data, mass balances were performed to introduce the constants (reaction and adsorption kinetics) to the LH-HW equation. With the analysis of the generation and consumption behavior of the organic intermediate compounds (OI), coupled differential equations were generated, which express the degradation and formation-consumption behavior. The kinetic constants were obtained by nonlinear regression using the Levenberg–Marquardt equation. The results show high removal percentages, and the behavior of the experimental data is assumed to fit the LH-HW equation. The analysis of the organic intermediates by solid phase micro-extraction (SPE), HPLC and gas chromatography (CG-MS), shows that the transformation is feasible under the formation of nitro-aromatic derivatives and hydroxylated species.

“…Exploration is being done into suitable surface, doping, noble metal loading, and hybrid composite materials in order to enhance the photocatalytic properties of semiconductor photocatalysts. Due to its great chemical stability, low resistivity (8.8 × 10 -5 Ω/cm at 300 K), and high melting point, molybdenum dioxide (MoO2) is a very significant, useful, and commonly utilized transition metal oxide [1][2][3][4]. Lithium-ion batteries, electrochemical super capacitors, and electrocatalysts have all recently used MoO2 as a host material [1] .…”

Lithium-ion batteries, electrochemical super capacitors, and electrocatalysts have all recently used MoO2 as a host material [1] . Materials with nanostructured MoO2 have stronger physicochemical qualities than materials with large MoO2, as they decrease the diffusion paths of electrons and ions, enhance the effective surface area, and have better reaction rate [ 5,6].…”

Hex ammonium molybdate (AHM), ammonium nitrate (NH4NO3), and glycine were used as the precursors in a microwave-assisted solution combustion synthesis (WSCS) process to create foam-like MoO2 nanoparticles. Methodically investigated was the effect of the glycine/NH4NO3 ratio (=0.25, 0.50, 0.75, 1.0 and 1.25) on the finished goods. The findings indicate that the final morphologies and phases of the products are virtually influenced by the value of Φ. MoO2 nanoparticles measuring 20 to 30 nm can be successfully composited under the condition of Φ=0.50 to produce a foam-like result. The photocatalytic activity of foam-like MoO2 nanoparticles was tested with several pollutants. The results show that foam-like MoO2 nanoparticles have good degradability and stability. The photocatalytic mechanism and fabrication mechanism of foam-like MoO2 has been presented in detail. Using foam-like MoO2-based photocatalyst materials for energy transfer and environment protection is supported by this research.
