Ag1Pd1 nanoparticle-reduced graphene oxide (Ag1Pd1-rGO) nanocomposite was used as an efficient catalyst for the synthesis of aromatic ketones via cross dehydrogenative coupling (CDC) reactions of 2-arylpyridines with aldehydes. The catalyst can be reused for 5 cycles without significantly losing its catalytic activity. On the basis of the obtained experimental evidence, we proposed a possible mechanism for the heterogeneous catalysis. We find that the supported catalysts exhibit a set of benefits, including extraordinarily catalytic activity, high reusability and remarkable tolerance of a variety of substrates.
