Nano-crystalline particles of CeO2 have been synthesized via a low temperature
hydrothermal synthesis process. Two types of precursors were studied—cerium hydroxide
and ceria acetate. The precursors were adjusted to a basic (pH 10) and acidic (pH 4)
medium before hydrothermal treatment at various durations of 6, 12, 18, and 24h at 250° C
using a Teflon-lined hydrothermal bomb. The synthesized samples were characterized
using DTA/TGA, XRD and TEM. Based on the characterization results, both precursor …

Nanosized CeO2 particles with a diameter of∼ 200 nm were successfully loaded on
activated carbon (AC) via a single-step hydrothermal process. The synthetic parameters,
including hydrothermal temperature, precursor concentration, and reaction time, were
regulated to control the size of the as-prepared CeO2 nanoparticles. The catalytic activity of
CeO2 nanoparticles/AC was investigated by dynamic adsorption of SO2 from simulated flue
gas, and the results exhibited remarkably enhanced SO2 adsorption capacity. The reaction …
