High precision and sensitivity of modern thermokinetic method was employed to investigate thermodynamic and kinetic regularities and characteristics of in situ growth process of nanomaterials including chemical reactions, nucleation growth, and crystal morphology and structure evolution. It has developed a novel

scientific principle and method for the controllable synthesis of nanomaterials. Thermodynamic property of nanomaterials determines their application in catalysis, energy storage, sensors, adsorption, etc. Three kinds of innovative solutions of chemical thermodynamics potential function method, electrochemical principle of reversible battery and modern thermokinetic method have been proposed to achieve nanothermodynamic functions, which was first reported by us in the international. It has supplied the effective scientific method and experiment technology for the building and development of nanothermodynamic theory.
