摘要：

According to the shape dependent melting temperature model for nanoparticles, an analytical model has been developed to describe the size, composition and shape dependent melting temperature. Results show that the size dependent melting temperature of bimetallic particles has a similar trend to that of the monometallic nanoparticles. The effect of composition on the melting temperature depends on the melting point of the component elements. The shape effect can be estimated by the surface/volume ratio of the bimetallic nanoparticles. The accuracy of our model is confirmed by recent molecule dynamic simulations.
