Abstract
Potassium-promoted Pd catalysts supported on MoO3 were prepared by incipient wetness co-impregnation techniques and characterized by XRD, TPR, TEM and activity for ethane hydrogenolysis and CO hydrogenation, in order to explore the nature of Pd-Mo interactions.
Results indicate that under reaction conditions the Pd surface is covered by Mo species which mask the catalytic characteristic of the group VIII metal. An explanation based on thermodynamic reasons is given.
期刊介绍：
Colloids and Surfaces A: Physicochemical and Engineering Aspects is an international journal devoted to the science underlying applications of colloids and interfacial phenomena.
The journal aims at publishing high quality research papers featuring new materials or new insights into the role of colloid and interface science in (for example) food, energy, minerals processing, pharmaceuticals or the environment.
