High specific surface area LaFeCo perovskites-Synthesis by nanocasting and catalytic behavior in the reduction of NO with CO
(ELSEVIER SCIENCE BV, 2009)
LaFe(1-x)CO(x)O(3) perovskites were conventionally or nanocasting synthesized. The nanocasting involved the preparation of a micro-mesoporous carbon mould using a Silica Aerosil 200 and a carbon source. Then, perovskites ...
CO preferential oxidation (CO-PROx) on La(1-x)Ce(x)NiO(3) perovskites
(ELSEVIER SCIENCE BV, 2011)
La(1-x)Ce(x)NiO(3) perovskites have been prepared, characterized by XRD. TPR and surface area and tested as catalysts for CO-PROx, with a feed of 2.5% CO, 5% O(2), 33% H(2) and N(2) to 100%. The samples exhibited an XRD ...
Study of La2-xCaxCuO4 perovskites for the low temperature water gas shift reaction
(ELSEVIER SCIENCE BVAMSTERDAM, 2012-01-31)
The effects of small fractions of calcium (x = 0, 0.05, 0.1, 0.15, and 0.20) on the structure and the catalytic properties of La2-xCaxCuO4 peroviskites have been investigated. The samples have been synthesized using the ...
Mechanochemical synthesis of ceramic powders with perovskite structure
(Elsevier B.V., 2003-12-20)
The mechanical activation is one of the most effective method for obtaining highly disperse system due to mechanical action stress fields form in solids during milling procedure. This effect results in changes of free ...
Nature of potential barrier in (Ca-1/4,Cu-3/4)TiO3 polycrystalline perovskite
(Elsevier B.V., 2006-01-01)
The nonohmic electrical features of (Ca-1/4,Cu-3/4)TiO3 perovskite ceramics, which have very strong gigantic dielectric is believed originate from potential barriers at the grain boundaries. In the present study, we used ...

Nb2O5 hole blocking layer for hysteresis-free perovskite solar cells
(2016-10-15)
Perovskite solar cells have attracted attention due its high conversion efficiency and low cost. In this work, Nb2O5 is used as an alternative compact hole blocking layer in conjunction with mesoporous TiO2 and CH3NH3PbI3 ...
