In this work, it was found that the surface area of silica-supported rhodium catalysts could be controlled in the range between 60 and 600m2/g by using the preparation method which we have developed using water-in-oil microemulsion. The catalysts with a controlled surface area had the same average size of rhodium particles. By using these catalysts, it was also found that turnover frequencies for CO2 hydrogenation increased linearly with the catalyst surface area.
