Oxygen reduction reaction activity of nitrogen-doped titanium oxide in acid media

Behavior of metal ions in bioelectrochemical systems: A review

“…Titanium, the most abundant element among the group 4 and 5 metals whose metal-oxide compounds have been regarded as promising candidates for fuel cells cathode catalysts due to their insolubility in acid media, has been much researched [198]. Titanium oxynitride and oxide of titanium carbonitride have been proved to have high ORR activity [198,199].…”

“…Titanium oxynitride and oxide of titanium carbonitride have been proved to have high ORR activity [198,199]. The nano-structure cathodes are also promising as an alternative to platinum-based cathodes applied in MFCs due to the relevantly easy preparation and low cost.…”

Synthesis of nano-TaOx oxygen reduction reaction catalysts on multi-walled carbon nanotubes connected via a decomposition of oxy-tantalum phthalocyanine

“…The electrode preparation and electrochemical measurements were conducted as described in ref. 16, except that a catalyst loading of 5 mg cm À2 was used in this study. The difference between the current obtained under oxygen and that under nitrogen (I O À I N ) was assumed to be responsible for the ORR.…”

Preparation of fibrous titania oxynitride – carbon catalyst and oxygen reduction reaction analysis in both acidic and alkaline media

“…The reaction is driven toward TiO2 formation in the presence of boric acid since fluoride anion is consumed by the formation of BF4 − [Equation (2)]. whereas peaks attributable to rutile TiO2 were mainly observed below 973 K [19].…”
