Abstract	The control over the size and location of metal nanoparticles (MNPs) within metal–organic frameworks (MOFs) is achieved in one step through a cooperative in situ metal precursor incorporation and on-site moderate reduction process, which is operated by a temperature control program. The choice of operation temperatures is based on the MOF assembly temperature (T1), and an elevated temperature (T2) to elicit the reducibility of DMF solvent to fabricate MNPs. Such a rational design could effectively introduce metal precursors into the pores of MOFs and on-site moderately reduce the embedded metal ions to generate tiny MNPs by the penetrated DMF, which could not be achieved by a quick heating process. The proposed methodology has been successfully applied to the one-step fabrication of ultrafine Pd NPs selectively encapsulated inside the pores of UiO-67 without any external reducing agents. The obtained Pd-in-UiO-67 shows superior catalytic activity and selectivity in the hydrogenation of styrene even at room temperature and atmospheric pressure of H2.
