Problem

Many metallic catalysts, particularly the precious-metal ones, are often deposited as very thin films on a substance of high surface area per unit mass, such as alumina (Al2O3) or silica (SiO2).

Why is this an effective way of utilizing the catalyst material compared to having powdered metals?
