| 1 | Sonochemical synthesis and characterization of uniform lanthanide orthophosphate(LnPO_4, Ln=La and Ce) nanorods显示文摘Uniform lanthanide orthophosphate(Ln PO4,Ln = La and Ce) nanorods were successfully synthesized by a simple ultrasonic irradiation method using lanthanide nitrate salt(Ln(NO3)3 6H2 O, Ln = La and Ce) and sodium phosphate(Na3PO4) in aqueous solutions with the p H of1–3. The products were characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM), transmission electron microscopy(TEM), high-resolution transmission electron microscopy(HRTEM), Fourier transform infrared spectrometer(FT-IR), and UV–visible(UV-Vis) spectroscopy. In this research, the products are nanorods of monoclinic La PO4 and hexagonal Ce PO4 structures and the vibration modes of PO43-, including the strong peaks at227 nm for La PO4, and at 225 and 278 nm for Ce PO4. | Anukorn Phuruangrat Titipun Thongtem Somchai Thongtem | 2015 | Rare Metals2015，34，5： | 4 |
| 2 | Facile sonochemical synthesis and photocatalysis of Ag nanoparticle/ZnWO4-nanorod nanocomposites显示文摘A facile sonochemical method was developed to synthesize metallic Ag spherical nanoparticles on the surface of ZnWO4 nanorods by forming heterostructure Ag/ZnWO4 nanocomposites.The Ag/ZnWO4 nanocomposites were characterized by X-ray powder diffraction (XRD),Fourier transform infrared spectroscopy (FTIR),field emission scanning electron microscopy (FESEM),transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS).The experimental results showed that fcc metallic Ag nanoparticles were supported on surface of monoclinic sanmartinite ZnWO4 nanorods.The Ag 3d3/2 and Ag 3d5/2 peaks have well-separated binding energies of 6.00 eV,certifying the existence of metallic Ag.The Ag/ZnWO4 nanocomposites were evaluated for photodegradation of methylene blue (MB) induced by ultraviolet-visible (UV-Vis) radiation.In this research,heterostructure 10 wt% Ag nanoparticle/ZnWO4-nanorod composites have the highest photocatalytic activity of 99% degradation of MB within 60 min.The increase in photocatalytic activity was the result of photoinduced electrons in conduction band of ZnWO4 that effectively diffused to metallic Ag spherical nanoparticles and the inhibition of electron-hole recombination process. | Phattranit Dumrongrojthanath Anukorn Phuruangrat Somchai Thongtem Titipun Thongtem | 2019 | Rare Metals2019，38，7： | 3 |
| 3 | Photocatalytic activity of La-doped ZnO nanostructure materials synthesized by sonochemical method显示文摘ZnO nanostructure materials doped with different La contents were synthesized by sonochemical method. The products were characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM),transmission electron microscopy(TEM), Raman spectroscopy, and Fourier transform infrared spectroscopy(FTIR). In this research, XRD patterns of pure ZnO and La-doped ZnO are specified as hexagonal wurtzite ZnO structure with no detection of La2O3 phase. SEM and TEM characterization revealed the flower shape of pure ZnO built-up from petals of hexagonal prisms with hexagonal pyramid tips. Upon doping with La, the flower-shaped ZnO is broken into individual 1D prism-like nanorods. Photocatalytic activities of the as-synthesized products were determined by measuring the degradation of methylene blue(MB) under ultraviolet–visible(UV) light irradiation.Among them, the 2.0 mol% La-doped ZnO shows better photocatalytic properties than any other products. | Anukorn Phuruangrat Phattranit Dumrongrojthanath Oranuch Yayapao Jirapong Arin Somchai Thongtem Titipun Thongtem | 2016 | Rare Metals2016，35，5： | 3 |
| 4 | Photoluminescence and photonic absorbance of Ce_2(MoO_4)_3 nanocrystal synthesized by microwave-hydrothermal/solvothermal method显示文摘In this research, cerium (Ⅲ) nitrate hexahydrate(Ce(N03)3-6H20) and ammonium molybdate tetrahydrate((NH_4)_6Mo_7O_(24)·4H_2O) with Ce^(3+)-to-Mo^(6+) molar ratio of2:3 were dissolved in 40 ml different solvents of deionized(DI) water, polyethylene glycol (PEG) and ethylene glycol(EG) to form different solutions which were followed by adjusting pH from the traditional values to 7.0 and 10.0 with1 mol-L^(-1) sodium hydroxide (NaOH). Subsequently, the solutions were processed by 270-W microwave-hydrothermal/solvothermal method. Phase, morphology, vibrational modes and photonic properties were fully characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM),Fourier transform infrared spectroscopy (FTIR), Raman spectrophotometry, ultraviolet-visible (UV-Vis) absorption and photoluminescence (PL) spectroscopy. The as-synthesized products were pure cerium molybdenum oxide(Ce_2(MoO_4)_3) of nanoparticles clustered together as nanoplates in DI water and PEG solvents, and of spindle-likenanoparticles in EG solvent, including the presence of CeO-H mode and M0O_4 units. The results show that direct energy gaps of the first two have the same value of 2.30 eV,and that of the last is 2.80 eV, including their blue emission at the same wavelength of 488 nm. | Wachiraporn Maisang Anukorn Phuruangrat Somchai Thongtem Titipun Thongtem | 2018 | Rare Metals2018，37，10： | 3 |
| 5 | Photocatalysis of Cd-doped ZnO synthesized with precipitation method显示文摘ZnO particles doped with 0 mol%-5 mol% Cd dopant were successfully synthesized by a precipitation method.The as-synthesized products were characterized by thermogravimetric analysis(TGA),differential scanning calorimetry(DSC),X-ray diffraction(XRD),photoluminescence(PL) spectroscopy,Raman spectroscopy,scanning electron microscopy(SEM) coupled with an energydispersive X-ray(EDX) spectroscopy and transmission electron microscopy(TEM).The precursors showed weight loss at 35-700℃ caused by phase transformation and evaporation processes.The as-synthesized products were specified as hexagonal wurtzite ZnO.The crystallite size of ZnO samples doped with 0 mol%-5 mol% Cd gradually increased with the increase in Cd content.The photocatalytic activities of 0 mol%-5 mol% Cd-doped ZnO samples were evaluated through photodecolorization of methylene blue(MB) under ultraviolet(UV) radiation.In this research,ZnO doped with 3 mol% Cd shows the best photocatalytic activity in degrading of MB molecules as much as 89% within 240 min. | Phattranit Dumrongrojthanath Anukorn Phuruangrat Somchai Thongtem Titipun Thongtem | 2021 | Rare Metals2021，40，3： | 2 |

| 14 | Synthesis and characterization of Gd-doped PbMoO_(4) nanoparticles used for UV-light-driven photocatalysis显示文摘Gd-doped PbMoO_(4) nanoparticles were prepared by a refluxing method at 80℃ for 2 h.Effect of molar content of Gd dopant on phase,morphology and optical properties was studied.The as-prepared Gddoped PbMoO_(4) samples can be indexed to pure tetragonal PbMoO_(4) phase.The particles size of PbMoO_(4) is decreased with increasing in the molar content of Gd dopant from 15.20±3.04 nm for pure PbMoO_(4) to 8.72±1.53 nm for 5 mol% Gd-doped PbMoO_(4).The absorption of 5 mol% Gd-doped PbMoO_(4) nanoparticles shows red-shift caused by lattice distortion of PbMoO_(4).The photocatalytic performance of 5 mol% Gddoped PbMoO_(4) nanoparticles shows the highest degradation of rhodamine B(RhB) of 97.92% under UV radiation and 67.65% under visible radiation because Gd^(3+) dopant as an electron acceptor plays the role in enhancing the separation of electron-hole pair. | Anukorn Phuruangrat Somchai Thongtem Titipun Thongtem | 2021 | Journal of Rare Earths2021，39，9： | 1 |
