Hey guys, I recently got some new additions to my supplies but while I do recognize most of them there are a few that I cannot for the life of me
figure out. One of them is a jar labeled "Ni - Catalyst for V 101" which doesn't really mean anything to me so I was hoping one of you might know.
They are pellets that look and feel kind of chalky, haven't run any actual tests on them yet. Really appreciate any info you can give me.

Hi Teloc,
A simple Google search yielded this:
https://www.sciencedirect.com/science/article/pii/S092058611...
Influence of group V elements such as Ta, Nb and V on the product distribution in the vapour phase hydrogenation of levulinic acid (LA) over Ni/TiO2
catalyst was examined at ambient pressure. The Nb promoted Ni/TiO2 demonstrated a high selectivity towards γ-valerolactone (GVL) compared to other
catalysts at 275 °C. The TPR results showed a lower H2 uptake over Ta and V modified Ni/TiO2 which was explained due to a strong interaction
between these oxide species with nickel. Presence of a high ratio of ionic nickel (Ni2+) on Ta and V modified catalyst could be a possible reason for
the formation of valeric acid (VA) through the ring opening of GVL......
The chalky feel is probably due to a low-density porous structure of the TiO2 support in what is probably a V-modified Ni-based vapor-phase
hydrogenation catalyst.
