An effective method has been developed for the preparation of highly dispersed Ag/CNT catalyst. We have introduced the principle of the functional ion preadsorption method and studied the optimum conditions of the catalyst preparation. On the basis of adsorption curves, TEM observations and catalytic activity analyses, it is found that the functional ion preadsorption is helpful for the formation and dispersion of small metal particles. The catalysts that were prepared under ultrasonic or ultrasonicmechanic agitation and high...
