Notes:
Abstract Pd supported on KL zeolite has been studied by temperature programmed reduction (TPR) and electron paramagnetic resonance (EPR) spectroscopy. It has been found that upon calcination in pure oxygen Pd3+ and Pd2+ ions are formed; the Pd3+ ions are identified by their EPR signal. As Pd3+ ions in the cancrinite cages are difficult to reduce, the H2 consumption in conventional TPR is below the stoichiometric amount.
