“…To date, various novel nonconventional carbonaceous materials, including ordered mesoporous carbons [4][5][6], carbon aerogels [7,8], carbon nanotubes (CNTs) [9][10][11][12], carbon nanohorns and nanocoils [13], and carbon nanofibers (CNFs) [10,11,14], have attracted extensive interest as the catalyst support, owing to their versatility in shape and dimension tailoring. Andersen et al [11] investigated the durability of CNFs and CNTs as catalyst supports, and they found both CNFs and CNTs had better stability than traditional carbon black, while CNFs showed a higher stability than CNTs during the entire investigation.…”

“…Moreover, the hydrogen adsorption area of Pt/PCNF‐CB‐30% is comparable to commercial catalyst Pt/C which are fabricated with advanced method. According to the equation: ECSA= Q /(0.21× M), where Q (mc) is the electrical charge associated with monolayer adsorption of hydrogen on Pt with an assuming value of 210 uC/cm 2 , M is the Pt loading on the working electrode. The resultant ECSA value of Pt/C, Pt/PCNF‐CB‐20%, Pt/PCNF‐CB‐30%, Pt/PCNF‐CB‐40% and Pt/PCNF‐CB‐50% are 91.7, 68.9, 87.7, 74.5 and 65.1 m 2 g ‐1 , respectively.…”

Porous carbon nanofiber (PCNF) was collaborated with carbon black (CB) to act as composite support (PCNF‐CB) to prepare platinum (Pt) catalyst (Pt/PCNF‐CB) by means of ethylene glycol reduction method. The electrocatalytic activity and stability of Pt/PCNF‐CB and the reference commercial Pt/C catalyst were investigated using cyclic voltammetry (CV) and linear sweep voltammetry (LSV). Among CB content of 20 wt% to 50 wt%, Pt/PCNF‐CB‐30% shows not only better catalytic activity in terms of onset potential and mass activity (MA), but also more durable than Pt/C. After 2000 accelerated potential cycles, Pt/PCNF‐CB‐30% exhibits 68% retention of electrochemical active surface area (ECSA) and 24 mV loss in half‐wave potential, while Pt/C gives 43% retention of ECSA and 94 mV loss in half‐wave potential. Significantly, the single cell performance confirmed that the MEA composed of Pt/PCNF‐CB‐30% as cathode catalyst reveals almost twice maximum power density than that composed of Pt/C catalyst.

“…9 However, carbon black suffers from being vulnerable to carbon corrosion, especially in harsh operating environment of PEM fuel cells, which might lead to the detachment and aggregation of catalyst metal particles. 5,6,8 Rather than carbon black, other carbonaceous materials have been investigated, so far, for this purpose, such as ordered mesoporous carbons, 4,10,11 carbon xerogel, 12 carbon nanotubes, 13 carbon nanofibers, 14 porous carbon nanofiber, 5 and graphene-based materials, 1, 15,16 to find the one with optimized form and structure for better efficiency and/or durability. It resulted that the support structure has a strong effect on the number and mechanism of electron transportation in ORR.…”

Increasing the efficiency of electrocatalyst is the key demand for the polymer electrolyte membrane fuel cells (PEMFC). To address the activity and performance challenges of commercial electrocatalyst, Pt/C, we introduce a new hybrid catalyst support for Pt nanoparticles. In this regard, combining or mixing specific type of carbon-based supports is a feasible strategy to increase catalyst utilization and performance. In the current study, Pt nanoparticles (NPs) were decorated on a new hybrid network, comprising of carbon nanofiber (CNF) and carbon black (CB), by means of a facile and efficient microwave (MW) assisted reduction method. All synthesized electrocatalysts were characterized to elucidate chemical and morphological structures. Then, the hybrid electrocatalysts were utilized as hydrogen oxidation reaction (HOR) and oxygen reduction reaction (ORR) electrocatalysts and their electrocatalytic activities were investigated by using cyclic voltammetry (CV) and linear sweep voltammetry (LSV), respectively. We found that the hybridization of CNF with CB substantially improved not only the electrocatalytic activity but also the fuel cell performance, which can be attributed to a consecutive conductive network, in which CB acts as a spacer, and synergistic effects between the CNF and CB. The hybrid electrocatalyst (Pt/CNF-CB with 50:50 wt%) showed a superior activity toward HOR and ORR while also offering exceptional fuel cell performance. That hybrid possessed the highest electrochemically active surface area (ECSA) compared with Pt/CNF and Pt/CB. In addition, the mass activity (at 0.80 V vs RHE) of the Pt/CNF-CB (50:50 wt%) is about 3.3 and 3.5 times higher than that of Pt/CNF and Pt/CB, respectively. Furthermore, that hybrid electrocatalyst exhibited enhanced fuel cell performance with 907 mW. cm −1 maximum power density. This work demonstrated that the CNF-CB supported Pt nanoparticles as electrocatalysts are extremely promising for fuel cell reactions.
