【 摘 要 】

Methane, the main constituent of natural gas (> 85%), is employed in large scale as an energy source (thermoelectric power plants, automobiles, etc). However, significant quantities of this gas contribute to the greenhouse effect. The catalytic combustion of methane can minimize these emissions. Palladium is one of the metals that shows the highest activity, depending on the different active forms of the metal. In this article, we focus on the influence of particle size and pretreatment on the catalytic performance of palladium in the methane combustion reaction.
