“…When this method is extended to the synthesis of bimetallic supported catalysts, an additional issue caused by the metal-metal interaction comes into the play, making a systematic approach difficult but highly desirable. So far, the number of research papers on supported bimetallic (thermo) catalysts obtained by ball milling is still quite limited [12][13][14][15][16][17][18][19][20][21][22]. However, some important elements have been highlighted.…”

“…However, some important elements have been highlighted. The simultaneous deposition of two metals can already be successfully obtained in short milling times and with relatively mild energy [13,19,21], but it strongly depends on the choice of the precursors and, possibly, on the support. Metal co-deposition is relatively easy with the appropriate conditions, but the formation of an alloy usually requires subsequent thermal treatments [13,20,21,23].…”

Mechanochemical synthesis for the preparation of bimetallic catalysts is gaining increasing interest, and in recent years, some important milestones have been reached. However, the complexity of mechanochemically prepared bimetallic supported catalysts still leaves many open questions that need a systematic approach to be solved. In this work, we summarize our experience of mechanochemically milling bimetallic catalysts, introducing some key parameters that should be taken into account, particularly the thermal stability and hydrophilicity of precursor salts, and the effect of the milling order, highlighting the differences with wet synthesis methods. Finally, we will provide some suggestions on the application of the design of experiments approach to the rationalization of the milling procedure for the preparation of supported bimetallic catalysts.
