Supported metal catalysts are an important group of heterogeneous catalysts used in many industrial processes, from chemical production and petrochemicals to air purification and exhaust systems. Among these, the most efficient and widely used are catalysts based on noble metals, which exhibit unparalleled activity and selectivity. However, these catalysts have several disadvantages: their production is very expensive and the availability of noble metals being low. Therefore, much effort has been devoted to finding adequate alternatives to noble metal catalysts. One of the most promising approaches is the development of supported bimetallic catalysts, which reduce the loading of noble metals by incorporating a wide variety of metal species. At the same time, bimetallic catalysts can provide good activity due to the synergistic effects that may occur between the two deposited metals, as well as between the metal species and the support. Many complex parameters influence the catalytic properties of bimetallic catalysts, and among the most important are the deposition method of the metal species, metal-support interactions, and the synergy between the two supported metals. A better understanding of these parameters and their relationships is crucial for the design and production of more efficient bimetallic catalysts containing highly available supports, such as alumina.
