Reducing the amount of rhodium used in catalytic processes without compromising performance is a significant challenge. One effective strategy is to use [bimetallic catalysts]() where rhodium is combined with another, less expensive metal such as palladium or platinum. This approach can enhance catalytic activity and selectivity while using less rhodium. Additionally, employing [nanoparticle catalysts](), which have a higher surface area-to-volume ratio, can result in more active sites per unit mass of rhodium, thereby reducing the required loading.
