Recently, Prof. Xiuting Li from the Institute for Advanced Study at Shenzhen University was invited and published a review paper titled "Electrodeposition of multi-component alloys: Thermodynamics, kinetics and mechanism " in Current Opinion in Electrochemistry.

Electrochemical deposition enters a new era since its application has extended to the modern fields of microelectronics and energy conversion, etc. Alloys play the vital role in these emerging applications, which necessitates the better understanding on the fundamentals of multi-component electrodeposition. In this review paper, the macroscopic behavior of the alloy electrodeposition in aspects of thermodynamics, kinetics and two representative peculiarities: anomalous co-deposition and induced co-deposition is first reviewed, followed by an overview of the microscopic mechanisms of nucleation and growth at early stages of deposition. Recent development in theoretical models and experimental practices are included and discussed.

This work was supported by the grants from the National Natural Science Foundation of China and the Project of Education Department of Guangdong Province.
