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

Abstract

One of the applications of nano-carbon is a support material of platinum (Pt) catalyst for fuel cells. In this study, the nanocarbon was successfully synthesized by in-liquid plasma in ethanol. The synthesized nano-carbon was characterized by the transmission electron microscope and the Raman spectroscopy. Moreover, the nano-carbon was applied to a support material of Pt catalyst for a proton exchange membrane fuel cell. The formation of the Pt particles on the nano-carbon was also carried out using the in-liquid plasma. The formed Pt/nano-carbon worked as a catalyst of the fuel cell. The fuel cell, fabricated with the Pt/nano-carbon catalyst, generated the maximum output power of 580 mW.

A Review of Plasma Synthesis Methods for Polymer Films and Nanoparticles under Atmospheric Pressure Conditions

“…Since the in-solution plasma is immersed in the solution, only reactions between the plasma and the solution occur in their entirety. Many recent papers about synthesis methods using in-solution plasma have mostly been reported on the formation of NPs [ 103 , 104 , 105 , 106 , 107 , 108 , 109 , 110 , 111 , 112 ].…”

“…Hyun et al [ 103 , 104 ], Panomsuwan et al [ 105 ], Morishita et al [ 106 ], Lee et al [ 107 ], Li et al [ 108 ], Tipplook et al [ 109 ], and Lee et al [ 91 ] used in-solution plasma systems generated by the plasma discharge between tungsten pin-to-pin electrodes, and Alsaeedi et al [ 110 ] chose carbon rods as the electrodes, as shown in Figure 10 , Figure 11 and Figure 12 . Hyun et al used a pair of tungsten electrodes 1 mm in diameter to generate the in-solution plasma; these electrodes were located at a distance of 1.5 mm from the glass reactor.…”

“…The carbon rod electrodes each had a diameter of 3 mm, and were separated by a gap of 1 mm. The electrodes were immersed in 50 mL of ethanol ( Figure 12 b), and the pulse voltage, frequency, and pulse width were 4 kV, 30 kHz, and 4 μs, respectively [ 110 ].…”

Novel nanocomposite membranes based on cross-linked eco-friendly polymers doped with sulfated titania nanotubes for direct methanol fuel cell application

“…Fuel cell technologies are new, attracting more attention as energy conversion tools targeting elimination of the fossil fuel pollution, 1,2 whereas fuel cell gives electricity with efficiency above 50% and can provide high power density for a long time at low operating temperatures. 3 Direct methanol fuel cells (DMFCs) are polymer electrolyte fuel cells having some advantages, such as methanol, as fuel has high hydrogen to carbon ratio (4:1), the simple design of the DMFC, and its eco-friendly impact.…”
