Electrochemical oxidation of sodium borohydride on carbon supported Pt-Zn nanoparticle bimetallic catalyst and its implications to direct borohydride-hydrogen peroxide fuel cell

Bimetallic Pd–Zn nanoalloys supported on Vulcan XC-72R carbon as anode catalysts for oxidation process in formic acid fuel cell

“…87-0638). The patterns of Pd n Zn/VC samples show similar characteristics, but the peaks are slightly shifted to higher values of 2q with the increase of the Zn content, which indicates a contraction of the lattice and the formation of alloy [22,23]. The absence of any peak of the Zn element or its compounds other than the PdZn phases in the XRD patterns suggests that samples are free from macroscopic phase segregation.…”

“…The absence of any peak of the Zn element or its compounds other than the PdZn phases in the XRD patterns suggests that samples are free from macroscopic phase segregation. The average crystallite size for the catalysts are calculated based on the (111) diffraction peak using Scherrer equation [22]:…”

Electrospun Pd nanoparticles loaded on Vulcan carbon/ conductive polymeric ionic liquid nanofibers for selective and sensitive determination of tramadol

“…However, there were no other distinct reflection peaks in the XRD patterns which could be assigned to the PdO or other Pd oxides. Moreover, the average size of the PdNPs was calculated 12.0 nm by Debye-Scherrer formula [35]. Fig.…”

Platinum-modified cobalt nanosheets supported on three-dimensional carbon sponge as a high-performance catalyst for hydrogen peroxide electroreduction

“…Over the years, the investigation of liquid-based FCs employing hydrogen peroxide (H 2 O 2 ) to replace oxygen (O 2 ) as oxidant (e.g. metal semi-FCs, direct borohydride-hydrogen peroxide FCs, direct methanol-hydrogen peroxide FCs, hydrazine-hydrogen peroxide FCs and direct peroxide-peroxide FCs) has been a hot topic [6][7][8][9][10][11][12][13]. Compared with O 2 , the electroreduction of H 2 O 2 takes place via a two-electron transfer involving the breakage of single dioxygen bonds 3 rather than the breakage of double bonds for O 2 reduction [14].…”

“…However, if the suitable hydrogen peroxide conditions (e.g. low concentration and operation temperature) are controlled, the chemical decomposition of hydrogen peroxide is not serious and can be easily handled [6][7][8][9][10][11][12][13].…”
