Pd(OAc)(2):pyridine (1:4) is an efficient catalyst system for the oxidation of alcohols with molecular oxygen. A mechanistic study of this reaction reveals that pyridine promotes the aerobic oxidation of palladium(0) but inhibits the oxidation of alcohol by palladium(II). Kinetic results reveal that turnover-limiting substrate oxidation consists of (i) formation of a palladium(II)-alkoxide, (ii...
Direct alkaline alcohol fuel cells (DAAFCs) have attracted increasing interest over the past decade because of their favourable reaction kinetics in alkaline media, higher energy densities achievable and the easy handling of the liquid fuels. In this review, principles and mechanisms of DAAFCs in alcohol oxidation and oxygen reduction are discussed. Despite the high energy densities available d...
Zinc ferrite (ZnFe2O4) nanoparticles were synthesized via the auto-combustion assisted sol-gel method of Zn2+ and Fe3+ ions (molar ratio 1:2) in ammonia solution. The prepared nanomagnetic catalyst was characterized by IR, XRD, SEM and ICP. The diameter of the ZnFe2O4 MNPs (63.7 nm) was determined by Debye-Scherre equation via their XRD pattern. Nanomagnetic ZnFe2O4 efficiently catalyzes oxidat...
