Abstract

Abstract

In this work, we prepared the La₂O₂CO₃/ZnO catalysts by two different methods-co-precipitation and ethylene glycol combustion method, whose catalytic performance of the dehydrogenation of ethanol to acetaldehyde as well as materials’ properties related to the catalytic behavior through FE−SEM, HR−TEM, FT−IR, XRD, N₂ adsorption/ desorption technique were investigated. The catalyst synthesis method had greatly influenced the morphology and performance, with materials prepared through solution combustion method better in terms of ethanol conversion resulted from the macroporous structure. Characterization results based on CO₂−TPD revealed that catalyst synthesized through co-precipitation or solution combustion method allowed correlation of acetaldehyde selectivity with basicity.
- co-precipitation method,
- solution combustion method,
