Title: Flame-Sprayed Pure and Ce-Doped TiO₂ Photocatalysts

Abstract

Pure and Ce-doped TiO₂ nanoparticles were successfully synthesized in one step by means of the scalable flame spray pyrolysis (FSP) process. Complete structural and chemical characterization of these materials revealed that the majority of the nanoparticles are crystalline and spherical, ranging from 5 to 45 nm in diameter. Furthermore, the band gap of TiO₂ was reduced by doping with Ce from 2.43 to 3.06 eV and the Ce–TiO₂ nanoparticles exhibit a strong photoelectrical response to visible light illumination. Ce–TiO₂ nanoparticles obtained with this scalable method are trivially scalable to industrial level manufacturing, granting and enabling additional approaches for the actual application of ceramic oxide nanomaterials to combat challenges such as environmental cleanup and energy production from the visible part of solar inputs.

Synthesis, performance evaluation, and economic assessment of tailored Pt/TiO ₂ catalysts for selective biomass vapour upgrading via a scalable flame spray pyrolysis route

Journal Article Kumar, Anurag ; Wang, Rongyue ; Orton, Kellene A. ; ... - Catalysis Science and Technology

Commercialization of next-generation nanostructured catalysts for biomass conversion is largely limited by the unique challenges associated with their large scale manufacture. In this work, we present the scalable, continuous synthesis of nanostructured Pt/TiO₂ catalysts in a single step via flame-spray pyrolysis (FSP) and demonstrate their utility in the upgrading of biomass vapours via catalytic fast pyrolysis (CFP). Spectroscopic and microscopic characterization of the catalysts prepared via FSP and conventional incipient wetness impregnation (IW) demonstrated that the FSP method enabled scalable production of Pt/TiO₂ with distinct Pt speciation (single atoms, clusters, and nanoparticles) that could be tuned by varying the Ptmore »« less

Preparation and properties of ce-doped TiO{sub 2} photocatalyst

Journal Article Yan, Ningning ; Zhu, Zhongqi ; Zhang, Jin ; ... - Materials Research Bulletin

Highlights: ► The cerium ion doped TiO{sub 2} (Ce-TiO{sub 2}) powders were prepared and characterized. ► The spectrum absorption region of Ce-TiO{sub 2} is red-shifted to visible light. ► The recombination of photo-generated electron-hole pairs of Ce-TiO{sub 2} is inhibited. ► The photocatalytic activity was effected by Ce ion content and greatly improved. -- Abstract: TiO{sub 2} nanoparticles doped with different content of Ce ion were prepared by sol–gel method. The samples were characterized by XRD, XPS, TEM, UV–Vis, and PL, the photocatalytic activity was evaluated by photocatalytic degradation of methylene blue (MB) under the irradiation of fluorescent lamp.

Synthesis of visible light-activated TiO{sub 2} photocatalyst via surface organic modification

Journal Article Dong, Jiang ; Graduate School of Chinese Academy of Sciences, Beijing 100039 ; Xu Yao ; ... - Journal of Solid State Chemistry

A visible light-activated TiO{sub 2} photocatalyst was successfully synthesized by the surface organic modification to sol-gel-hydrothermal synthesized TiO{sub 2}. The surface hydroxyls of TiO{sub 2} nanoparticles reacted with the active -NCO groups of tolylene diisocyanate (TDI) to form a surface complex that was confirmed by the FT-IR and XPS spectra. Due to the existence of surface complex, the absorption edge of as-prepared TDI-modified TiO{sub 2} nanomaterial extended well into visible region. Compared with unmodified TiO{sub 2} and Degussa P25, the TDI-modified TiO{sub 2} photocatalysts showed higher activity for the photocatalytic degradation of methylene blue under visible light irradiation. - Graphicalmore »« less

Influence of Ce doping on optical and dielectric properties of TiO{sub 2}

Journal Article Naseem, Swaleha ; Khan, Wasi ; Naqvi, A. H. - AIP Conference Proceedings

Rare earth ion (Ce) doped TiO{sub 2} and pure TiO{sub 2} nanostructured were prepared by sol gel acid modified technique and calcinated at 450°C. Microstructural studies and thermal analysis were carried by XRD and TGA respectively. The results of structural characterization show the formation of all samples in single phase without any impurity. Optical properties were studied by UV- visible spectroscopy and band gap energy was estimated 3.04 eV and 3.14 eV for pure and Ce doped TiO{sub 2} respectively. Room temperature dielectric constant (ε’) decreases abruptly at lower frequencies owing to the charge transport relaxation. The observed behavior ofmore »« less

Flame spray pyrolysis optimization via statistics and machine learning

Journal Article Paulson, Noah H. ; Libera, Joseph A. ; Stan, Marius - Materials & Design

Flame spray pyrolysis (FSP) is an important manufacturing process whereby nanomaterials are produced through the combustion of atomized fuel containing dissolved precursor elements. While FSP has the potential to enable the scalable production of a wide range of next generation energy materials, it also has a multi-scale, multi-physics character, and a large number of processing variables. Optimizing the process for desirable material outcomes by traditional approaches is challenging. In this work, the processing parameter space is explored new and efficient methodology that includes statistical methods such as Latin hypercube design of experiments, machine learning surrogate modeling, and Bayesian optimization.
