Abstract

•Pd-UiO-66 with ultra-low Pd loading (0.05 wt%) contains three active Pd species.•Pd1-Pdc-Pdn/UiO-66 presents superb performance toward toluene oxidation.•Consecutive atmosphere regulation is the key to Pd1-Pdc-Pdn/UiO-66 formation.•Residual N species from solvent enter UiO-66 skeleton forming Pd1-N1 structures.•Synergistic effect of Pd1, Pdc, Pdn for toluene oxidation are elucidated by DFT.
