La perovskita LaNiO3 fue sintetizada por cuatro métodos diferentes: autocombustión, sol-gel, calcinación de nitratos y freeze-drying. El catalizador que presentó la mayor actividad en términos de conversiones de CH4 y CO2 a H2/CO fue el provenie

La perovskita LaNiO3, tanto reducida como no reducida, se evaluó en la reacción de descomposición del metano a 600°C y 700°C. El Ni°/La2O3 obtenido por este procedimiento mostró la más alta actividad en la descomposición de metano, además l

LaNiO3 perovskite, both reduced and non-reduced, was evaluated in the decomposition of methane at 600°C and 700°C. The Ni°/La2 O3 obtained by reduction of LaNiO3 showed the largest methane decomposition activity and also the highest yield of hydro

Perovskite-type LaNiO3 was synthesized by four different methods: autocombustion, sol-gel, calcination of nitrate and freeze-drying. The catalyst that presented the highest activity in terms of conversion of CH4 and CO2to H2/CO was obtained from pero

Interface optimisation for continuous hemp reinforcements in epoxy resin is a current challenge for the development of biocomposites. A chemical treatment based on hydrogen peroxide and a physical one using a non-thermal plasma have been tested to op

In this work we present a green synthetic pathway for the obtaining of bio-surfactants derived from glycerol. By extending a Lewis acid catalyzed reaction between glycidol and primary alcohols we obtained good conversion to the desired monoalkylglyci

The selective preparation of monoalkylglyceryl ethers (MAGEs) is a task for researchers owing to their broad range of applications. In this work, green feedstocks such as glycidol and alcohols were used to prepare MAGEs under mild reaction conditions
