This report describes the methodology for the fabrication of mesoporous In2O3 microflowers by
hydrothermal and calcination procedures in which In(OH)3/In2S3 acts as an intermediate. Both In2O3 and
its precursor were analyzed with scanning electron microscopy, energy dispersive X-ray
spectrophotometry, transmission electron microscopy and powder X-ray diffraction. BET surface area,
pore size and pore volume analyses were also carried out. Electron microscopy images clearly evidence
the self-assembly of 2D nanosheets into the micro flower structure. The mechanism of self-assembly
and calcination is reported. Electrochemical properties of the synthesized In2O3 micro flowers were
studied.peerReviewe
