MWCNT-Supported PVP-Capped Pd Nanoparticles as Efficient Catalysts for the Dehydrogenation of Formic Acid

Abstract

Various carbon materials were used as support of polyvinylpyrrolidone (PVP)-capped Pd nanoparticles for the synthesis of catalysts for the production of hydrogen from formic acid dehydrogenation reaction. Among investigated, MWCNT-supported catalysts were the most promising, with a TOF of 1430 h −1 at 80 • C. The presence of PVP was shown to play a positive role by increasing the hydrophilicity of the materials and enhancing the interface contact between the reactant molecules and the catalytic active sites.

Highly Stable N-Doped Carbon-Supported Pd-Based Catalysts Prepared from Biomass Waste for H2 Production from Formic Acid

“…), and Pd/HTC, respectively). Such a positive effect of nitrogen in attaining good catalytic performance in the dehydrogenation of formic acid has been attributed to both the participation of nitrogen atoms in the reaction by interacting with formic acid molecules and increasing the local concentration close to the Pd active sites and the role of nitrogen in modifying the electronic properties of Pd atoms. ,, …”

XPS Pd spectrum contains two asymmetric doublets that can be assigned to 3d 5/2 and 3d 3/2 transitions, at lower and higher binding energies, respectively.…”

Controlled synthesis of mono- and bimetallic Pt-based catalysts for electrochemical ethanol oxidation

“…J o u r n a l P r e -p r o o f 6 Carbon black CD6008 employed as support for the catalysts preparation was provided by Columbian Chemicals Company (Brunswick, Ohio). Its specific surface area, determined by applying the Brunauer, Emmett and Teller (BET) method to the N2 adsorption isotherm at 77K, is 605 m 2 g -1 and the mesopore volume was 0.38 cm 3 g -1 [37].…”

“…This method has been extended for a wide variety of metal nanoparticles to be used in a large number of applications (e.g. dehydrogenation of formic acid [37], oxygen reduction reaction [38] or sensing applications [39,40]). In fact, reduction of the metal catalyst in presence of the carbon material support has offered a good distribution of the nanoparticles onto the support with high reproducibility and loading.…”
