| Description |
Carbon supported RuSe (RuSe/C) catalyst in varying atomic
ratios of Ru to Se, namely, 1:1, 2:1, and 3:1 were prepared
and their performances were compared with carbon supported
Ru (Ru/C). Based on the performance, Palladium
was incorporated into as prepared RuSe(2:1)/C and heat
treated HTRuSe(2:1)/C. Ru/C, RuSe/C, and Pd-RuSe/C
were characterized by X-ray diffraction (XRD) and transmission
electron microscopy techniques. The XRD analyses of
Ru/C, RuSe/C and Pd-HTRuSe/C show the formation of
the hcp structure of Ru particles and the mean particle size
was obtained from Ru(101) peak. The electrochemical characterizations
of Ru/C, RuSe/C, Pd-HTRuSe(2:1)/C and Pd-
RuSe(2:1)/C were conducted by cyclic voltammetry. Linear
Sweep Voltammetric studies showed that incorporation of
Pd in HTRu-Se(2:1)/C resulted in better catalytic activity
toward oxygen reduction with resistance to methanol oxidation.
The quantity of hydrogen peroxide produced was
obtained from rotating ring disk electrode studies
