“…Recently special attention has been paid to the development of nanocomposite materials based on graphene oxide (GO), reduced graphene oxide (rGO) [24][25][26][27]. Presently special attention is paid to the development of palladium/platinum based catalysts, for fuel cells with direct oxidation of formic acid [6,8,10,13,14,17,20,[27][28][29][30][31]. This type of chemical power sources has a number of advantages over other types of hydrogen-containing fuels: 1) fuel cells with direct oxidation of formic acid have a high open circuit potential at room temperature; 2) formic acid is a non-toxic liquid fuel; 3) in contrast to methanol, it is possible to use highly-concentrated formic acid as a high specific energy fuel; 4) formic acid is an electrolyte, therefore it can facilitate the transfer of protons inside the anode space.…”

In the present experimental work new polymer-reduced graphene oxide (rGO) nanocomposites with bimetallic platinum-palladium nanoparticles as functional electrodes for chemical power sources were prepared. The size and shape of nanoparticles in the composites have been studied by use of atomic force and high-resolution transmission electron microscopy techniques, X-ray phase analysis and small-angle X-ray scattering. Model tests on the basis of chemically-obtained composite electrodes under operating conditions of fuel elements with formic acid oxidation were carried out.

“…DFAFC has a number of advantages over direct methanol fuel cells [1]: (i) it has higher power density and higher energy efficiency, (ii) crossover flux of formic acid through Nafion5 membrane is several times smaller than that of methanol [2], and (iii) formic acid is less toxic than methanol and does not have the risk of producing hazardous by-products during oxidation (e.g., formaldehyde). A number of reviews on DFAFC [1,[3][4][5][6][7][8] have been published.…”

The performance of Pd electrocatalysts for formic acid electrooxidation was improved by application of metal oxide-multiwall carbon nanotubes composites as a catalyst support. Hybrid oxides/MWCNTs were synthesized by two different methods: chemical reduction method and impregnation method. Pd based catalysts were synthesized by polyol method on the MWCNTs or oxide/MWCNTs composites. The In 2 O 3 was deposited on MWCNTs by impregnation method (In 2 O 3 /MWCNTs-IM support) and in the presence of NaBH 4 (In 2 O 3 /MWCNTs-NaBH 4 support). The physical properties of the Pd/In 2 O 3 /MWCNTs-IM, Pd/In 2 O 3 /MWCNTs-NaBH 4 , Pd/SnO 2 /MWCNTs, and Pd/MWCNTs catalysts were characterized and their electrocatalytical performance in formic acid oxidation was compared. During Pd deposition on In 2 O 3 /MWCNTs-NaBH 4 support, InPd 2 structure was formed as observed by XRD. The electrochemical tests indicate that the two Pd/ In 2 O 3 /MWCNTs electrocatalysts have higher electrocatalytic activity than those of Pd/SnO 2 /MWCNTs and Pd/MWCNTs. The best performance was observed for the catalyst obtained by In 2 O 3 impregnation of MWCNTs denoted by Pd/In 2 O 3 /MWCNTs-IM.
