چکیده:

in has been established that the gold containing catalysts such as Au/Fe2o3 display high catalytic activity in a series of important reactions the paper concerns the preparation of nano scale Au/Fe2o3 catalyst by a deposition -precipitation method in order to optimize experimental conditions and find out the effective factor in preparing Au/Fe2o3 catalyst taguchi design method was used the effects of the calcination temperature reaction time and the HAuCl4 .3H2O concentratin on particle size and gold loading and specific surface area of the catalyst particles are investigated throw XRD X-ray diffraction bet bruuner -emmett-teller SEM scanning electron micriscopy techniques.
