N2 - Most of simple oxalates of late d-elements decompose to form highly dispersed metal, and this property can be transferred to double oxalates. In this case, a bimetallic nanoalloy could be expected as a thermolysis product, which may be useful in catalytic applications. The introduction of other metals into Ir can improve the effectiveness of Ir-based catalysts and decrease the Ir loading.
