The growth pattern of the Pt5Ce nanoparticles during the synthesis.

Caption

According to different mechanisms of the particle growth, the synthesis process is divided into three sequential periods, namely, Period 1, when the Pt4+ ions are reduced to Pt nanoparticles; Period 2, when Pt nanoparticles react with the Ce2(CN2)3 to form Pt5Ce; and Period 3, when the Pt5Ce particles grow further due to the prolonged heat-treatment at 650 °C.
