High performance platinized titanium nitride catalyst for methanoloxidation

Abstract

Platinized TiN is shown to be a very good catalyst for the electrochemical oxidation of methanol; it does not contain Ru and the CO poisoning effect is alleviated by the presence of TiN.

Transition Metal Carbides and Nitrides as Electrode Materials for Low Temperature Fuel Cells

“…In one case, Pt loaded TiN showed the electroactivity for methanol oxidation [111]. As shown in Figure 13, Pt/TiN deposited on stainless steel substrate showed the high I f /I b ratio representing the high CO resistance in voltammogram performed with a scan rate of 20 mV/sec in 0.5 M CH 3 OH + 0.5 M H 2 SO 4 electrolyte.…”

Intermittent microwave synthesis of nanostructured Pt/TiN–graphene with high catalytic activity for methanol oxidation

“…The oxidation peak at the same potential appears in the first, but disappears during the second sweep. According to the literatures [7,23], the increasing current at this potential arises from oxidation reaction resulting in formation of TieOH: …”

“…Although the Pt/G and Pt/TiNeG catalysts have approximately the same ECSA of Pt, the methanol oxidation activity of the Pt/TiNeG catalyst is twice as much as that of the Pt/G catalyst as discussed above, which suggests that the TiN plays an important role in promoting methanol electro-oxidation. It could be probably attributed to both the formation of eOH groups on the surface of TiN [7,9], and the special structures that some Pt nanoparticles surrounded TiN nanoparticles on graphene [20,21].…”

“…However, the widespread use of PteRu catalyst is limited by their noble prices, so research and development of alternative catalyst materials are still a matter of great urgency in nowadays. Musthafa et al reported that TiN can be used as a supporting material for methanol oxidation [7], and found that eOH groups decomposed from water can be formed on TiN leading to a high methanol oxidation activity which is similar to PteRu [8,9]. However, the poor electrical conductivity of TiN nanoparticles limits their practical application in DMFCs [10].…”

Facile preparation of mesoporous titanium nitride microspheres as novel adsorbent for trace Cd2+ removal from aqueous solution

“…TiN is often deposited on the surface of titanium, steel and aluminum components in order to protect their properties [3]. Recent researches show that TiN can be employed in a wide variety of fields including catalysis, sensors, electroanalysis, and energy storage both in Li-based batteries and supercapacitors [4][5][6]. In addition, TiN also shows promising photocatalytic property and good biocompatibility [7,8].…”
