Abstract:
Herein, we highlighted fluorine-anion-modification as a useful method for enhancing OER catalytic activity. Fluorine-anion-doped Ni foam exhibits an almost 10-fold enhancement in OER catalytic activity. Moreover, fluorine-anion-modification could be used as a general method to greatly increase the OER activity of NiAl LDHs. The strongly electronegative F anion is favorable to build weak metal-fluorine bonds, which easily break to form active species of nickel oxides/hydroxides, enhancing OER catalytic performance.

Noble Gases
The elements in group 18 are noble gases (helium, neon, argon, krypton, xenon, and radon). They earned the name “noble” because they were assumed to be nonreactive since they have filled valence shells. In 1962, Dr. Neil Bartlett at the University of British Columbia proved this assumption to be false.
