Possible Interaction: Niobium and Iron, Dietary

“Transition metal oxides are usually not efficient catalysts because they are more selective to produce H2 O. Here, it is shown that divalent 3d transition metal cations (Mn, Fe , Co, Ni, and Cu) can control the catalytic activity and selectivity of columbite nanoparticles.”

“We found that by co-annealing Nb films with Fe in Argon gas at above 400 $$^{\circ }$$ ∘ C for an hour, one can induce a Kondo effect in Nb.”

“The responses ((Rg - Ra)/Ra, where Rg is the resistance in gas and Ra is the …, benzene, p-xylene, HCHO, CO, H2, and NH3 at 350-500 ° C were significantly enhanced by Fe … NiO nanofibers, while the responses of pure NiO nanofibers … ((Rg - Ra)/Ra = 0.07-0.78).”

“Doping NiO nanoplatelets by Fe greatly improves their sensing performance.”
