Rhodium (Rh) has received widespread attention in fundamental catalytic research and numerous in-dustrial catalytic applications. Compared to homogeneous catalysts, Rh-based nanomaterials as heteroge-neous catalysts are much easier to separate and collect after usage, making them more suitable for com-mercial use. To this purpose, there has been a constant demand in constructing stable and highly active Rh-based nanomaterials. In contrast to Rh-based solid solutions with a random distribution of metallic atoms in the lattice, Rh-based intermetallic compounds (IMCs) with a fixed stoichiometric ratio and an or-dered atomic arrangement can ensure the homogenous distribution of active sites and structural stability in the catalytic process. In this review, we concentrate on the fabrication of Rh-based IMCs for catalytic applications. Various synthetic methods and protocols for the controlled preparation of Rh-based IMC are illustrated. Meanwhile, the catalytic applications and corresponding catalytic mechanisms are discussed. In addition, personal perspectives about the remaining challenges and prospects in this field are pro-vided. We believe this review will be useful in directing the development of Rh-based IMC catalysts for heterogeneous catalysis.
