Deoxygenation of Palmitic Acid on Unsupported Transition

Abstract.Highly active bulk transition-metal phosphides (WP,MoP,and Ni 2 P) were synthesized for the catalytic hydrodeoxygenation of palmitic acid,hexadecanol,hexadecanal,and microalgae oil.The specific activities positively correlated with the concentration of exposed metal sites,although the relative rates changed with temperature due to activation energies varying from 57 kJ mol 1 for MoP to 142Design of a Surface Alloy Catalyst for Steam Reforming The heat of solution of Au in Ni is large and positive (27 kJ/mol).Yet it has been found in STM studies by Nielsen et al.that when Au is added to any of the low index Ni surfaces,an alloy is formed in the first atomic layer (Fig.1).The Ni atoms in the surface layer are undercoordinated compared with the Ni

transition metal Definition,Properties,Elements

Transition metal,any of various chemical elements that have valence electronsi.e.,electrons that can participate in the formation of chemical bondsin two shells instead of only one.While the term transition has no particular chemical significance,it is a convenient name by which to distinguish the similarity of the atomic structures and resulting properties of the elements so designated.
