Pt catalyst supported on titanium suboxide for formic acid electrooxidation reaction

Electrocatalysis of titanium suboxide-supported Pt–Tb towards formic acid electrooxidation

“…Recently, Ti 4 O 7 has been found to be a promising support material owing to its higher corrosion resistance and superior electrical conductivity than carbon black [15]. In our previous work [16], it is shown that Pt catalyst supported on Ti 4 O 7 possesses better catalytic activity and stability than Pt catalyst supported on carbon black and commercial TiO 2 for formic acid electrooxidation. Besides the high electrical conductivity of the Ti 4 O 7 support material, the performance improvement was mainly ascribed to the higher content of metallic Pt caused by Ti 4 O 7 .…”

On the stability of platinum-composite electrocatalysts prepared with different substrate materials

“…There are studies showing better MEA stability and activity of Pt nanoparticles supported on mesoporous TiO 2 in comparison to commercial carbon as a support [14,15]. However, there are rather opposite findings for the influence of TiO 2 to Pt electrocatalysis; there are papers reporting the improvement for oxygen reduction kinetics [16,17] and the activity in H 2 evolution [18], but some results show that TiO 2 -supported Pt suffers from significantly lower activity in H 2 and O 2 reactions than Pt supported on carbon [19]. Hence, it could be of interest to take into consideration new approaches in composite catalyst synthesis and more detailed analysis of electrocatalytic properties of synthesized materials, able to mutually produce new findings and benefits for Pt catalysts supported on materials other than carbon of rather modest properties.…”

Development of microforming process combined with selective chemical vapor deposition

“…Especially for medical devices, biocompatibility of metal has been highly required, and its miniaturization technology is needed. Additionally bio-devices with noble metal or nanomaterials, such as gold (Au), platinum (Pt) and Carbon nanotubes (CNTs) on the surface, are often used in bio-technology by exerting good functions like detecting antibody [1] or catalytic reaction [2]. And, the nano-structuration technologies for functional surface are also required to increase these functions [3].…”
