Abstract
Nanoparticle catalyst compositions and methods for preparation of same are described. The nanoparticle catalysts are platinum-free and are useful in effecting selective ring-opening reactions, for example in upgrading heavy oil. The catalyst may be of monometallic composition, or may comprise an alloyed or core-shell bimetallic composition. The nanoparticles are of controlled size and shape.
