Preparation of the vulcan XC-72R-supported Pt nanoparticles for the hydrogen evolution reaction in PEM water electrolysers

Abstract

Pt nanoparticles on vulcan XC-72R support (Pt/vulcan XC-72R) were prepared by the impregnation–reduction method. The Pt content, the morphological properties and the electrochemical catalysis of the Pt/vulcan XC 72R materials have been investigated by ICP-OES analysis, FESEM, TEM, and cyclic voltammetry. These materials were then used as catalyst for hydrogen evolution reaction at the cathode of proton exchange membrane (PEM) water electrolysers. The best catalyst was Pt/vulcan XC-72R prepared by the impregnation–reduction method which is conducted in two reducing steps with the reductants of sodium borohydride and ethylene glycol, respectively. The current density of PEM water electrolysers reached 1.0 A cm−2 when applying a voltage of 2.0 V at 25 °C.

Fast and Facile Synthesis of Pt Nanoparticles Supported on Ketjen Black by Solution Plasma Sputtering as Bifunctional HER/ORR Catalysts

“…Hydrogen adsorption and desorption peaks were observed for Pt/KB in the potential range of 0.05-0.30 V for the reverse and forward scans, respectively. The electrochemical active surface area (ECSA) can be evaluated by integrating the area under the hydrogen adsorption or desorption peak, which was considered as an indicator of the number of catalytic Pt sites on the catalysts [19,20,23]. We found that the higher loading of Pt nanoparticles on KB, the larger the area under the hydrogen adsorption or desorption peaks.…”

“…Among active catalyst materials, platinum (Pt) is the most efficient catalyst for both HER and ORR [19][20][21][22]. In practical use, Pt nanoparticles (2-5 nm) are loaded onto various kinds of material supports (e.g., carbon black [23], carbon nanotubes [24], graphene [25], or metal oxide [26]) for use as HER/ORR catalysts. The most common method for synthesizing Pt nanoparticles relies on the bottom-up chemical reduction in water-soluble Pt 2+ or Pt 4+ ions as precursors (e.g., H 2 PtCl 6 , K 2 PtCl 4 , PtCl4, and Pt(AcAc) 2 ).…”

Calcined Co(II)-Triethylenetetramine, Co(II)- Polyaniline-Thiourea as the Cathode Catalyst of Proton Exchanged Membrane Fuel Cell

“…Pt-catalysts for proton exchanged membrane fuel cells (PEMFCs) are carbon black (Vulcan XC-72) implanted with Pt nanoparticles (Pt/C) [ 1 , 2 ]. The carbon black (CB) subtracts function for both the conducting medium for the transportation of electrons from either cathode or anode, and O 2 trappers with suitable sizes of pores.…”

Synthesis of nano-carbon by in-liquid plasma method and its application to a support material of Pt catalyst for fuel cell

“…These Pt catalysts are usually supported on high-surface carbon and/or nano-carbon such as Vulcan XC-72, and so on. [5][6][7][8] The support carbon materials are manufactured from the hydrocarbons such as natural gas or oil fractions by the pyrolysis process. These support carbon materials are commonly used for the PEMFC at present.…”
