Enhanced photocatalytic activity through anchoring and size effects of Au nanoparticles on niobate nanotubes and nanosheets for water splitting

Shiqi Zhao, Xiaorong Cheng, Anthony Centeno, Graham Dawson

Summary: In this study, nanotubes and nanosheets of H4Nb6O17 were prepared and attached with Au nanoparticles of two different sizes. The composites were characterized and their activity towards H2 generation by photocatalytic water splitting was investigated. The results showed that the morphology of the nano-niobate had minimal effect for the directly attached Au particles, but a significant difference was observed for the APTES-anchored Au particles. The APTES-Au-nanosheets exhibited a much higher hydrogen production rate compared to the parent niobate nanotubes, indicating that morphology and different interactions played important roles in photocatalytic efficiency.

Toxicity evaluation of TiO2/MWCNT-CNF hybrid nanocomposites with enhanced photocatalytic activity toward freshwater microalgae: Pseudokirchneriella subcapitata

Terrence S. Malatjie, Tarryn L. Botha, Alex T. Kuvarega, Ntakadzeni Madima, Karin de Bruyn, Memory Tekere, Thabo T. Nkambule, Bhekie B. Mamba, Titus A. M. Msagati

Summary: A wide range of semiconductor-assisted photocatalytic nanomaterials are being investigated as potential photocatalysts in water treatment. The use of nanocomposites composed of nano-TiO2 and MWCNTs is increasing due to their enhanced photocatalytic efficiency. However, the potential risks of these nanosystems in aquatic systems are not well understood. In this study, the toxic effects of TiO2/MWCNT-CNF nanocomposite on freshwater microalgae were assessed. The nanocomposite showed enhanced dye removal performance but also caused algal growth inhibition and sublethal oxidative stress effects. These findings contribute to a better understanding of the potential hazards of nanocomposites in wastewater treatment.

Aqueous Methanol to Formaldehyde and Hydrogen on Pd/TiO2 by Photocatalysis in Direct Sunlight: Structure Dependent Activity of Nano-Pd and Atomic Pt-Coated Counterparts

Naresh Nalajala, Kranti N. Salgaonkar, Inderjeet Chauhan, Siva Prasad Mekala, Chinnakonda S. Gopinath

Summary: The study synthesized facet-controlled Pd nanoparticles with different morphologies and Pt-coated Pd nanoparticles, finding that Pt-coating enhances catalytic activity, with 0.5θ(Pt)-Pd-TO/P25 showing the highest methanol conversion rate and formaldehyde selectivity. The results highlight the importance of surface properties in heterogeneous catalysis and suggest that a small amount of Pt can simulate the activity equivalent to bulk Pt.

Evolution of photocatalytic activity of CeO2-Bi2O3 composite material for wastewater degradation under visible-light irradiation

Keshavulu Masula, Yadagiri Bhongiri, G. Raghav Rao, P. Vijay Kumar, Someshwar Pola, Manohar Basude

Summary: Ce-doped bismuth oxide showed potential applications in photodegradation of dye pollutants and agrochemical wastewater, due to its reduced band gap energy and increased photocatalytic activity. The Ce doping led to changes in the phase and surface area of the bismuth oxide, resulting in enhanced absorption of visible light and reduced recombination rate of electron-hole pairs.

Microwave-assisted reflux synthesis of Tungsten-doped BiVO4 for improved photocatalytic activity

Barbara Scola Rodrigues, Carolyne Martins Branco, Lucas Rafael de Moura Domingos, Ivanise Gaubeur, Zhiyu Wang, Changqiang Chen, Mauro R. Sardela, Juliana dos Santos Souza

Summary: This study describes a pioneering method of microwave-assisted reflux synthesis of W-BiVO4, which allows for the preparation of efficient photocatalysts in a short period of time. Tungsten doping and control of the structure and morphology of the mixture play an important role in the photocatalytic performance, while the addition of PVP helps to control the morphology. However, adding PVP may result in lower material efficiency.

Summary: The study reveals that transition metal carbides and nitrides (MXenes) are inorganic compounds with two-dimensional structures. These substances are primarily composed of some atomic layers of transition metal carbides, nitrides, or carbonitrides. Ti3C2, the primary 2D-layered MXene, was first isolated in 2011. The conversion of mechanical, electrical, and electronic properties of MXenes highlights their exciting potential in energy storage, conversion, and utilization.

Dielectric Properties and Spectral Characteristics of Photocatalytic Constant of TiO2 Nanoparticles Doped with Cobalt

Valentin G. Bessergenev, Jose F. Mariano, Maria Conceicao Mateus, Joao P. Lourenco, Adwaa Ahmed, Martin Hantusch, Eberhard Burkel, Ana Maria Botelho do Rego

Summary: The dielectric properties and spectral dependence of the photocatalytic constant of Co doped P25 Degussa powder were studied. The research showed a concentration limit for cobalt distribution in the TiO2 matrix before metallic clusters form, and the formation of CoTiO3 phases during annealing at high temperatures. The temperature dependence of the dielectric constant indicated relaxation processes at temperatures below 400 degrees C and Ti-O octahedron reorientation at higher temperatures. The spectral dependency of the photocatalytic constant revealed the presence of electronic states within the energy gap of TiO2 for all nanopowdered samples.

Enhanced photocatalytic hydrogen production by the formation of TiNT-BN bonds

Yanan Zhao, Shiqi Zhao, Hailian Huang, Zijie Liu, Xiaorong Cheng, Graham Dawson

Summary: In this study, composites between TiNT and BN were prepared by a new mixed hydrothermal/solvothermal method at different temperatures, and compared to physical mixing. The composites showed enhanced photocatalytic hydrogen production, with the composite prepared at 140 degrees C exhibiting Ti-O-B bond formation and the highest efficiency of 1600 mu molg-1hr-1. The structural and optical properties, as well as charge carrier lifetime, were investigated to understand the enhanced activity, and a band diagram was proposed to explain the results.

Transition metal dichalcogenides nanomaterials based piezocatalytic activity: recent progresses and outlook

Arup Kanti Kole, Srikanta Karmakar, Ashim Pramanik, Pathik Kumbhakar

Summary: Piezoelectric materials have gained attention for their ability to generate electricity through the piezoelectric effect when subjected to external stress. Transition metal dichalcogenides (TMDCs) have shown promise in this area due to their tunable electronic structure and catalytic activity. However, they exhibit poorer piezocatalytic activity compared to electrocatalysis or photocatalysis. To overcome this, researchers have explored methods such as synthesizing different TMDC nanostructures and coupling the piezoelectric and photocatalytic effects. This review summarizes the synthesis techniques and applications of TMDC nanomaterials in piezocatalysis, as well as discusses charge transfer behavior and catalytic mechanisms.

Summary: This study reports the solvothermal synthesis of CuCdS2 nanoparticles assisted by ethylene glycol. The crystalline nature of the material with a hexagonal phase is confirmed by X-ray diffraction pattern. The average particle size of the synthesized material is 37 nm, as revealed by FE-SEM micrographs. UV-Visible absorption results show that the nanoparticles have a wide range of absorption up to the mid-visible region, with an optical band gap of 1.67 eV. The synthesized material exhibits a photocatalytic response, degrading 68.5% of Methylene Blue (MB) under solar irradiation.
