Preparation of Pt catalysts decorated TiO2 nanotube arrays by redox replacement of Ni precursors for proton exchange membrane fuel cells

Electrochemical oxygen reduction behaviour of platinum nanoparticles supported on multi-walled carbon nanotube/titanium dioxide composites

“…Yao et al synthesised platinised fibre-like Ti 4 O 7 which showed superior durability as well as enhanced Pt mass activity in comparison to commercial Pt/C catalyst in 0.5 M H 2 SO 4 [54]. Pulsed electrodeposition technique was employed by Zhang et al to synthesise and deposit Pt nanoparticles onto the TiO 2 nanotube arrays as a support for fuel cells [55]. Dual-gun sputtering technique was used for the preparation of TiO 2 nanotube arrays as carbon-free support for PtCo catalyst.…”

Recent progresses in H2-PEMFC at DICP

“…What's more, preparing MEAs with catalyst slurry requires high control accuracy. Thin ordered electrode structure is a new choice to reduce the Pt loading [22,23] . In the ordered electrodes, the transportations of gas, electron and proton are improved by the ordered channels, and the thin catalyst layer is beneficial for removing the water generated.…”

Effect of ethylene glycol on electrochemical and morphological features of platinum electrodeposits from chloroplatinic acid

“…For the application of such coatings, the supports used were usually metallic and nonmetallic materials which are characterized by very high degree of adhesion for the coating of the metallic deposits [1]. Recently, significant interest has been raised in utilizing electrodeposition for the formation of an array of metal nanoparticles on the surface of different carbon supports [2,3]. The reason for this particular interest is to obtain M/C materials with maximum electrochemically active surface area, which requires formation of the electrodeposits not only on the surface but also in the pores of the carbon support.…”
