Intimacy promotes good chemistry: Time-resolved hard X-ray diffraction (see picture) and dispersive X-ray absorption spectroscopy coupled to time-resolved IR spectroscopy allows direct observation and quantification of the ability of materials to store and release gases under specific conditions. The nanoscale Pd/CeZrO4 interface plays a reactively deterministic role in inducing a superior performance in these catalysts.
