Abstract The temperature which is required to reduce Co2+ ions in NaY can be markedly lowered by the presence of Pd in the same zeolite. Temperature programmed reduction (TPR) in combination with diffuse reflectance spectroscopy shows, however, that the reducibility of Co is enhanced only if Pd2+ and Co2+ ions share the same zeolite cages. No hydrogen spillover effect is detected, if this proximity requirement is not fulfilled.
