Platinum-catalyzed Nb–doped TiO2 and Nb-doped TiO2 nanotubes for hydrogen generation in proton exchange membrane water electrolyzers

High electrocatalytic activity of Pt on porous Nb-doped TiO2nanoparticles prepared by aerosol-assisted self-assembly

“…This dispersion indicates good contact between the catalyst and support, allowing the supported catalyst to exhibit good electronic conductivity. 28 This layer structure of the platinum nanoparticles was further demonstrated by the EDS line scanning proles, as shown in Fig. 3.…”

Methanol Steam Reforming on Bimetallic Catalysts Based on In and Nb Doped Titania or Zirconia: A Support Effect

“…It is worth noting that the catalytic activity of Cu0.8-Ni0.2/Ti0.9Nb0.1O2.05 an Ni0.2/Zr0.9Nb0.1O2.05 samples turned out to be relatively close. It was noted in [43] highly defective cubic modification formation, characterized by high oxygen mo Therefore, the most probable reason is the effect of a significant difference in the defect structure of the obtained carriers. Thus, doping titania with indium oxide takes place due to the quasi-chemical reaction (3).…”

“…It is worth noting that the catalytic activity of Cu 0.8 -Ni 0.2 /Ti 0.9 Nb 0.1 O 2.05 and Cu 0.8 -Ni 0.2 /Zr 0.9 Nb 0.1 O 2.05 samples turned out to be relatively close. It was noted in [43] that the highly defective cubic modification formation, characterized by high oxygen mobility, is favorable to provide a high catalytic activity of the systems containing zirconia-based supports. However, both catalysts based on titania have the same anatase structure and differ only in the defective center's nature.…”

“…In recent years, considerable attention has been paid to supports based on titanium oxide, which is primarily associated with their use in photocatalytic transformations [39][40][41][42]. However, they started to be actively used in other areas, such as hydrogen production using electrolysis [43]. There are data about methanol steam reforming on titania-based catalysts [33,44,45].…”

Photocatalytic fuel cell – A review

“…Pt foil, Pt wire, carbon paper deposited with Pt-black or carbon-black, etc. [75,[100][101][102][103][104][105] The high cost of Pt is one of the major challenges.…”
