  The effects of dimension-eight operators giving rise to anomalous neutral
triple gauge boson interactions of $Z\gamma\gamma$ and $Z\gamma Z$ vertices in
$pp\to l^-l^+\gamma$ and $pp\to \nu\bar \nu \gamma$ are investigated at 100 TeV
centre of mass energy of future circular hadron collider (FCC-hh). The
transverse momentum of photon, invariant mass of $l^-l^+\gamma$ and angular
distribution of charged lepton in the rest frame of $l^-l^+$ and Missing Energy
Transverse (MET) are considered in the analysis. The realistic detector effects
are also included with Delphes simulation. Sensitivity limits obtained at 95\%
C.L. for $C_{\widetilde B W}/\Lambda^4$ and $C_{B B}/\Lambda^4$ couplings are
$[-0.52;0.52] ([-0.40;0.40])$ TeV$^{-4}$, $[-0.43;0.43] ([-0.33;0.33])$
TeV$^{-4}$ in the dilepton+photon channel and $[-0.11;0.11] ([-0.084;0.084])$
TeV$^{-4}$, $[-0.092;0.092] ([-0.072;0.072])$ TeV$^{-4}$ in the MET+photon
channel with $L_{int}$=1 (3) ab$^{-1}$, respectively.
