Catalyst performance is influenced by a variety of factors in the preparation process.To optimize the catalyst preparation formulations and process conditions,a lot of manual trial and error experiments are usually required,resulting low efficiency and precision.With the development of mechanical automation control,the development and implementation of high-throughput synthesis devices will improve the efficiency,accuracy and safety of the catalyst preparation process.In this review,we describe how high-throughput synthesis devices such as thin film deposition,microfluidics,automated synthesis robots,and inkjet printing can help to enhance the process of catalytic material preparation and accelerate the process of catalyst formulation optimization,starting from the commonly used synthesis methods for metal catalysts including impregnation,ion exchange,chemical vapor deposition,and precipitation deposition.This paper will focus on the one-to-one correspondence between the needs of metal nano-catalyst synthesis processes and the characteristics of high-throughput synthesis devices.As the demand for high-flux synthesis technology is increasing day by day,the construction of a practical platform for high-flux synthesis of metal catalysts can bring great impetus to the research of catalysts.
