Pd nanocrystals encapsulated in MOF-derived Ni/N-doped hollow carbon nanosheets for efficient thermal CO oxidation: unveiling the effect of porosity by Ipadeola, Adewale K.

“…The thermal COOxid activity of Pd/Ni-MOF-HNC was significantly superior to Pd/Ni-MOF-NC and commercial Pd/C catalysts. This is evidenced in the great ability of Pd/Ni-MOF-HNC to utterly oxidize CO at a lower complete conversion temperature (T100) of 114.5 °C compared with Pd/Ni-MOF-NC (153.8 °C) and Pd/C (201.5 °C) under atmospheric pressure. …”

Influence of nitrogen doping on the electrocatalytic activity of Ni-incorporated carbon nanofibers toward urea oxidation by Barakat, Nasser A.M.

“…However, the electrochemical measurements indicated that the content of the urea in the initial electrospun solution should be optimized as the results showed that the best nickel surface activation as well as the maximum observed current density can be achieved when the urea content is kept at 5 wt%. Typically, the observed current densities using 1.0 M urea (in 1 M KOH) were 3.15, 29.7, 13.75, 47.55, 14.13 and 9.85 mA/cm2 for the nanofibers obtained from electrospun solutions having 0, 1, 2, 5, 7 and 9 wt% urea, respectively. …”
