Álvarez, Pablo; Araya Figueroa, Paulo; Rojas, René; Guerrero, Sichem; Aguila, Gonzalo (Sociedad Chilena de Química, 2017)The activity of Fe2O3/Al2O3 catalysts prepared by impregnation of Al2O3 with different amounts of Fe and calcination temperatures (650 and 900 degrees C) in the direct N2O decomposition reaction was studied. High calcination ...

López, Naima; Aguila, Gonzalo; Araya, Paulo; Guerrero, Sichem (Elsevier Science BV, 2018)A novel core-shell K/Cu/SmCe@TiO2 catalyst is here reported being highly active on the selective reduction of nitric oxide with carbon monoxide under oxidizing conditions. It was found that the reaction proceeds with the ...

Morales, Camila; López, Naima; Aguila, Gonzalo; Araya Figueroa, Paulo; Scott, Felipe; Vergara Fernández, Alberto; Guerrero, Sichem (Elsevier, 2019)A set of Cu/Ce/TiO2-SiO2 and K/Cu/Ce/TiO2-SiO2 catalysts was used for the simultaneous use of CO and naphthalene as reducing agents for the reduction of NO in the presence of oxygen. Only 5% of TiO2 greatly increase the ...

Aguila, Gonzalo; Guerrero, Sichem; Baeza, Patricio; Araya, Paulo (Elsevier Ltd, 2019)© 2018 Elsevier B.V. This work studies the effect of different Cu/Ce loading ratios in the formation of highly dispersed copper species being interacting with CeO2 on zirconia-supported CuO–CeO2 catalysts. These species ...

Álvarez, Pablo; Aguila, Gonzalo; Guerrero, Sichem; Araya, Paulo (Sociedad Chilena de Quimica, 2018)The effect of the support on the formation of the Cu-CeO2 interface and its thermal stability after calcination at 500, 700 and 900 ºC is studied. The supports used are SiO2 , because of its inert character, and ...
