This research designs a new method that can control the nucleation and growth environment of metastable nanocrystals, and further achieve the controllable synthesis of metastable multicomponent metal and metal chalcogenides nanocrystals. On the basis of further systematic research on the relationship between the metastable structure and the catalytic performance of the catalyst which has the best effect, this thesis aims to solve the existing problems which electrocatalyst has to face in the regenerable hydrogen-oxygen fuel cell area. Furthermore, this research provides the theoretical basis and practi-cal guidance for the mass production of nanoparticles, which have special properties, and for the design of ad-vanced nanoelectronic devices.
