Microwave-Assisted Synthesis and Luminescence of Mesoporous RE-Doped YPO₄ (RE = Eu, Ce, Tb, and Ce + Tb) Nanophosphors with Lenticular Shape

Rodríguez Liviano, Sonia Aparicio Rebollo, Francisco Javier Rojas Ruiz, Teresa Cristina

Mesoporous tetragonal RE:YPO₄ nanophosphors (RE = Eu, Ce, Tb, and Ce + Tb) with a lenticular morphology, narrow size distribution, and high surface area have been prepared by an homogeneous precipitation procedure consisting of aging, at low temperature (80–120 °C) in a microwave oven, ethylene glycol solutions containing only yttrium...

Characterization of active sites/entities and redox/catalytic correlations in copper-ceria based catalysts for preferential oxidation of CO in H2 rich streams

Martínez Arias, Arturo Gamarra, Daniel Hungría, Ana B.

This article reviews work done at authors' laboratories about catalysts based on combinations between copper and ceria for preferential oxidation of CO in H2-rich streams (CO-PROX). The main focus of this review is the characterization of active sites for the process on the basis of spectroscopic analysis of the systems under reaction...
