Uniform CdMoO 4 nanooctahedra with tunable sizes have been synthesised via a facile and mild microemulsion method at room temperature. The reaction between CdMoO 4 nanooctahedra and dilute hydrochloric acid was in situ monitored using microcalorimetry at 298.15 K, and microcalorimetric heat flow curves from this reaction process were obtained. Combined with an inductively coupled plasma optical emission spectrometer technique, the size effect of CdMoO 4 nanooctahedra on standard molar reaction enthalpy (Δ r H m Θ ) was studied. The results indicate that the value of Δ r H m Θ decreased with decreased particle size.
