Abstract: In the background of new nano-gold composite materials development and gold industry transformation,the study explores and practices the industrial production of Au/C nano-gold composite materials.The paper mainly introduced the process of the industrial production of Au/C nano-gold composite materials,in terms of its principle,approaches to the industrial production system,equipment selection design for the industrial production,and its core technology and the production practice explored.The practice shows that the nano-gold particles produced by the Au/C production process are all in the state of even dispersion and dont fall off after multiple washing because of the intense interaction between nano-gold and activated carbon surface that guarantees the load capacity of particles.Besides,the diameter of nano-gold particles concentrates on 5 nm and the size distribution is homogeneous,which ensures its quality for subsequent use.The study makes demonstrations for the industrialized development of other new materials.
