Abstract/OtherAbstract:
This work describes a new one step method for the preparation of AuNPs/LDH nanocomposites via the polyol route. The novelty of this facile and simple synthesis is the absence of additional reactants such as reductive agents or stabilizer, that gives the possibility to obtain phase pure systems free of undesiderable effect. The AuNPs formation is confirmed by SEM, TEM, PXRD, XAS; moreover the electrochemical characterization is also reported. The electrocatalytic behavior of AuNPs/LDH nanocomposites has been investigated towards the oxidation of methanol in basic media and compared with that of pristine NiAl-Ac. The 4-time highest catalytic efficiency observed with AuNPs/LDH nanocomposites suggests the presence of a synergic effect between Ni and AuNPs sites. The combination of these experimental findings with the low cost synthesis procedure paves the way to the exploitation of the presented nanocomposites materials as catalysts for methanol fuel cells.
