Ultrasmall (1–2 nm) CeO2 nano-islands dispersed on a silica support surface significantly contribute to active and super-stable dry reforming of methane with CO2 to produce syngas over a Ni-based catalyst, which is attributed to controllable charge transfer between Ni particles and CeO2 islands and largely suppressed carbon deposition.
