Mechanochemical Synthesis of Yttrium Oxide and Hydrogen Peroxide via Planetary Ball Milling With Nickel Catalyst: Structural, Morphological, and Particle Size Analysis
Abstract
This
study
investigates
the
mechanochemical
synthesis
of
Yttrium
Oxide
(Y₂O₃)
and
Hydrogen
Peroxide
(H₂O₂)
via
planetary
ball
milling,
with
a
focus
on
catalytic
effect
nickel.
Hydride
(YH₃)
was
milled
under
hydrogen
atmosphere,
both
without
nickel
catalyst,
to
assess
influence
various
process
parameters
such
as
milling
time,
pressure,
catalyst
presence
phase
transformation,
crystallite
size,
particle
morphology,
size
distribution.
X-ray
diffraction
(XRD),
scanning
electron
microscopy
(SEM),
energy
dispersive
spectroscopy
(EDS),
laser
analysis
(PSA)
were
used
characterize
samples.
Results
show
that
catalysis
significantly
enhances
reaction
kinetics,
reduces
promotes
uniform
morphology
compared
non-catalyzed
Catalyzed
samples
exhibited
faster
transformation
from
YH₃
Y₂O₃,
reduction

nm
near-complete
formation
Y₂O₃
H₂O₂.
These
findings
demonstrate
nickel-catalyzed
offers
an
efficient
scalable
route
for
synthesis,
potential
applications
in
catalysis,
storage,
environmental
remediation.
Further
research
optimizing
conditions
exploring
other
catalysts
is
recommended.
