Effect of the dopant on the structural and hyperfine parameters of Sn0.95M0.05O2 nanoparticles (M: V, Mn, Fe, Co)
(IOP Publishing, 2019-06)
In this work, we present a comparative study of the structural and hyperfine parameters on tin dioxide nanoparticles doped with different transition metal elements. The nanopowders with the stoichiometry Sn0.95M0.05O2 (M: ...
MICROWAVE-ASSISTED HYDROTHERMAL SYNTHESIS OF Ni-DOPED SnO2 NANOPARTICLES AND THEIR USE AS CATALYSTS IN BIODIESEL PRODUCTION
(Centro Federal Educacao Tecnologica Rio Grande Norte, 2017-01-01)
The high chemical stability and low cost of tin dioxide has been widely reported in the literature, as has its microwave-assisted hydrothermal synthesis. The use of heterogeneous catalysts in biodiesel synthesis has proved ...
Quantification of MgO surface excess on the SnO(2) nanoparticles and relationship with nanostability and growth
(ELSEVIER SCIENCE BV, 2011)
In this work, we experimentally showed that the spontaneous segregation of MgO as surface excess in MgO doped SnO(2) nanoparticles plays an important role in the system`s energetics and stability. Using Xray fluorescence ...
Rare Earth Doped SnO(2) Nanoscaled Powders and Coatings: Enhanced Photoluminescence in Water and Waveguiding Properties
(Amer Scientific Publishers, 2011-03-01)
Luminescent Eu(3+) and Er(3+) doped SnO(2) powders have been prepared by Sn(4+) hydrolysis followed by a controlled growth reaction using a particle's surface modifier in order to avoid particles aggregation. The powders ...

Relationship between surface segregation and rapid propane electrical response in Cd-doped SnO2 nanornaterials
(ELSEVIER SCIENCE SA, 2008)
Controlling the surface properties of nanoparticles using ionic dopants prone to be surface segregated has emerged as an interesting tool for obtaining highly selective and sensitive sensors. In this work, the surface ...
Structural and magnetic properties of pure and nickel doped SnO(2) nanoparticles
(IOP PUBLISHING LTD, 2010)
Ni-doped SnO(2) nanoparticles prepared by a polymer precursor method have been characterized structurally and magnetically. Ni doping (up to 10 mol%) does not significantly affect the crystalline structure of SnO(2), but ...
A new method to control particle size and particle size distribution of SnO2 nanoparticles for gas sensor applications
(Wiley-Blackwell, 2000-07-05)
The controlled growth of SnO2 nanoparticles for gas sensor applications is reported by these authors. Nb2O5 additive is used to control nucleation and growth of the SnO2 (see Figure), which is synthesized by the polymeric ...

SnO2 nanoparticles functionalized in amorphous silica and glass
(Elsevier B.V. Sa, 2009-10-25)
Two different routes to obtain SnO2 nanoparticles, undoped and doped with rare earth metals (Eu or Pr), are described herein. The first route was based on the polymeric precursor method that led to the obtainment of SnO2 ...
