We discuss recent work on reaction-diffusion processes that take place on complex networks. The inherent inhomogeneity of the substrate leads to a series of new phenomena, which bear only a small resemblance to the classical results of the field. The annihilation rate is abnormally high in such systems, while at the same time depletion zones are absent in the reaction and no segregation is observed for the reaction. These results are mainly attributed to the presence of network hubs and to the small network diameter of such systems.
