“…For instance, RGO nanoplatelets act as spacers between the platinized carbon black agglomerates, decreasing the catalytic layer percolation threshold (electronic conductivity) [12] and enhancing mass transfer [11]. Carbon black durability could be increased, for example, through the preparation of composites with stable oxides [13,14] or using any heteroatom doping approaches [15]. Several alternatives, such as carbon nanotubes [16], nanofibers [17], mesoporous carbons [18], and graphene-based materials [19][20][21][22][23], have been considered.…”

Platinum (Pt)-based electrocatalysts supported by reduced graphene oxide (RGO) were synthesized using two different methods, namely: (i) a conventional two-step polyol process using RGO as the substrate, and (ii) a modified polyol process implicating the simultaneous reduction of a Pt nanoparticle precursor and graphene oxide (GO). The structure, morphology, and electrochemical performances of the obtained Pt/RGO catalysts were studied and compared with a reference Pt/carbon black Vulcan XC-72 (C) sample. It was shown that the Pt/RGO obtained by the optimized simultaneous reduction process had higher Pt utilization and electrochemically active surface area (EASA) values, and a better performance stability. The use of this catalyst at the cathode of a proton exchange membrane fuel cell (PEMFC) led to an increase in its maximum power density of up to 17%, and significantly enhanced its performance especially at high current densities. It is possible to conclude that the optimized synthesis procedure allows for a more uniform distribution of the Pt nanoparticles and ensures better binding of the particles to the surface of the support. The advantages of Pt/RGO synthesized in this way over conventional Pt/C are the high electrical conductivity and specific surface area provided by RGO, as well as a reduction in the percolation limit of the components of the electrocatalytic layer due to the high aspect ratio of RGO.

“…The promising strategy aimed to mitigate carbon supports limitations is using of carbon-based hybrid supports. One of the most attractive materials is a tin oxide (SnO 2 ) owing to its availability, cost-effectiveness, and non-toxicity [7,[13][14][15][16][17][18][19][20][21][22]. The tin oxide-carbon composites are attractive due to their high oxidation resistance properties, as well as an improved electrochemical activity for the oxygen reduction reaction (ORR) as compared to Pt/C [23].…”

A detailed study of the structure, morphology and electrochemical properties of Pt/C and Pt/x-SnO2/C catalysts synthesized using a polyol method has been provided. A series of catalysts supported on the SnO2-modified carbon was synthesized and studied by various methods including transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), electrochemical methods, and fuel cell testing. The SnO2 content varies from 5 to 40 wt %. The TEM images, XRD and XPS analysis suggested the Pt-SnO2 hetero-clusters formation. The SnO2 content of ca. 10% ensures an optimal catalytic layer structure and morphology providing uniform distribution of Pt-SnO2 clusters over the carbon support surface. Pt/10wt %-SnO2/C catalyst demonstrates increased activity and durability toward the oxygen reduction reaction (ORR) in course of accelerated stress testing due to the high stability of SnO2 and its interaction with Pt. The polymer electrolyte membrane fuel cell current–voltage performance of the Pt/10wt %-SnO2/C is comparable with those of Pt/C, however, higher durability is expected.

“…Thus, to overcome durability issues, CBs can be combined with other materials, which can make the support material more stable without compromising on electrical conductivity. 72,73 For instance, CBs can be combined with the metal oxides to utilize the combined benefits of highly stable metal oxides and highly conducive CBs. The main attributes associated with such hybrid materials are higher corrosion resistance, better metal support interactions, and improved hydrophilicty (which may counter water management issues) accompanied with higher electrical conductivity.…”

Recent advances in hybrid support material for Pt‐based electrocatalysts of proton exchange membrane fuel cells

Summary Proton exchange membrane fuel cell is an energy conversion technology with an excellent potential to replace fossil fuel–based internal combustion engines. Evenly distributed Pt on conductive support is commonly used as an electrocatalyst. This catalyst support material is a key component of proton exchange membrane fuel cell as it greatly affects the cost, durability, and electrochemical activity of fuel cells. Although the carbon‐based support materials have evolved in the last few decades, there is still need to explore other alternatives as the corrosion of carbon is inevitable under the harsh environments within the catalyst layer of proton exchange membrane fuel cells. Moreover, the performance of noncarbon supports is also not satisfactory. Therefore, the advent of hybrid support materials, which are electrochemically stable and cost‐effective, is required. The hybrid supports exhibiting the characteristics of contributing component, or even showing synergistic effect, would circumvent the shortcomings associated with individual components. This review introduces the recent advances in hybrid support materials, including carbonaceous and noncarbonaceous one; discusses the pros and cons of different support materials; and highlights the improved properties of hybrid supports as compared with the individual components.
