  • Nano-crystal palladium was prepared through the chemical liquid phase synthesis method.Thermal stability study shows that the average diameter of n-Pd against the annealing temperature fits Arrhenius relation(in the temperature range of 773~523K).The average diameter against the annealing time fits the empirical formula =ktn.The thermal stability temperature is below 250℃。By calculating,we get the apparent growth activation energy about 0.15eV,which is far smaller than ordinary nano-composite material.So,n-Pd is very easy to grow,and possesses a narrow thermal stability temperature range.

Abstract: Nano-crystal palladium was prepared through the chemical liquid phase synthesis method.Thermal stability study shows that the average diameter of n-Pd against the annealing temperature fits Arrhenius relation(in the temperature range of 773~523K).The average diameter against the annealing time fits the empirical formula =ktn.The thermal stability temperature is below 250℃。By calculating,we get the apparent growth activation energy about 0.15eV,which is far smaller than ordinary nano-composite material.So,n-Pd is very easy to grow,and possesses a narrow thermal stability temperature range.
