Nickel catalysts supported on ZrO2, Y2O3-stabilized ZrO2 and CaO-stabilized ZrO2 for the steam reforming of ethanol: Effect of the support and nickel load
(ELSEVIER SCIENCE BV, 2008)
Catalysts with various nickel loads were prepared on supports of ZrO2, ZrO2-Y2O3 and ZrO2-CaO, characterized by XRD and TPR and tested for activity in ethanol steam reforming. XRD of the supports identified the monoclinic ...

(Soc Brasileira Quimica, 2013-03)
SYNTHESIS AND CHARACTERIZATION OF NANOSTRUCTURED CaZrO3 AND BaZrO3.
In this work, nanostructured samples of barium zirconate (BaZrO3) and calcium zirconate (CaZrO3) were synthesized by the gel-combustion method, using ...
Síntese direta do acetato de etila a partir do etanol sobre catalisadores de Au, Cu e AuCu suportados em zircônia monoclínica (m-ZrO2)
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2018-03-09)
The ethanol conversion into ethyl acetate is a very important reaction, in economic and scientific fields. In the context of science, the propose of this work was to evaluate the activity of Au and Cu catalysts supported ...
Influence of phase composition on the sliding wear of composites in the system CaZrO3–MgO–ZrO2 against ZrO2 and steel
(Elsevier Science, 2016-10)
An attractive way to obtain low cost calcium zirconate (CaZrO3) composites is mixing natural limestone or dolomite with zirconia. These CaZrO3 based ceramic composites were often investigated as a promising high refractory ...
Effective strategy to coupling Zr-MOF/ZnO: Synthesis, morphology and photoelectrochemical properties evaluation
(2021-01-01)
Zr-MOF was coupled with ZnO particles by mechanical mixture followed by heat treatment at 400 °C. The Zr-MOF influence on the ZnO structure was investigated by means of X-ray diffraction (XRD), surface area analysis (BET), ...
Microwave-assisted hydrothermal synthesis followed by heat treatment: A new route to obtain CaZrO3
(2018-01-01)
CaZrO3 nanoparticles were obtained by a new synthesis route: nucleation using the microwave-assisted hydrothermal method (MAH) and crystallization by heat treatment. Structural characterization by X-ray diffraction (XRD) ...
