Effect of TiO 2 Loading on Pt-Ru Catalysts During Alcohol Electrooxidation

Influence of Pt/Ru anodic ratio on the valorization of ethanol by PEM electrocatalytic reforming towards value-added products

“…Therefore, the increase in the Ru content could interfere in the cubic platinum structure, reducing the crystallinity of the system. In addition, the shifts of Pt reflections revealed alloy formation between Pt and Ru [23][24][25][26]. Table 1 collects data of the lattice parameter, Pt (2 2 0) angle and degree of alloyed Ru.…”

Research and innovation in the electrocatalyst development toward glycerol oxidation reaction

“…The presence of ruthenium oxide and tin oxide in the tertiary oxide catalyst brought in higher surface area and donated large amounts of OH species. Hasa et al 172 also synthesis Pt − Ru − TiO 2 electrodes and found that the addition of TiO 2 affected the size of Pt and Ru where the higher the loading of titanium dioxide, the smaller the crystallite size of the metals. The catalyst displayed higher current density and the electrocatalytic rate at optimum titanium oxide loading compared to pure Pt-Ru catalyst.…”

Advanced catalyst supports for PEM fuel cell cathodes

“…General properties of non-carbon support (mainly ceramic materials) include corrosion-resistance, potential strong metal-support interaction, and stable porous structure, but these materials suffer from low electrical conductivity and low porosity. Several types of non-carbon supports have been investigated, including titanium oxide [79][80][81][82][83], cerium oxide [84,85], niobium oxide [86], tungsten oxide [87][88][89], some carbides [90][91][92][93][94][95][96], nitrides [97], oxy-nitrides [98], borides [99] and conductive polymer [100,101]. Figure 4a gives typical polarization curves of the PEM fuel cells using Pt/TiO 2 and Pt/C as electrocatalysts [80].…”
