Defective MOFs Microreactor with Heterojunction for Selective Methane Photocatalysis via Desorption‐Driven Overoxidation Suppression

open access: yesAdvanced Science, EarlyView.
A defect‐engineered MOFs microreactor is constructed to regulate product desorption to suppress overoxidation by integrating Cu single atoms anchored on polymeric carbon nitride into the defective NH2‐UiO‐66. In photocatalytic oxidation of CH4, Def‐CuCN/NU enhances CH4 adsorption and CH3OH desorption, while the type‐S heterojunction enhances charge ...

ZIF‐67‐Confined Pd Single‐Atom Catalysts Implanted Into Polydopamine‐Modified Bamboo Microchannels for Robust Continuous‐Flow Hydrogenation

open access: yesAdvanced Science, EarlyView.
The report presents a facile room‐temperature method to stabilize Pd single‐atom catalysts within ZIF‐67 crystals during their formation. Despite an ultralow Pd loading (0.0014 wt%), the catalytic microreactor, featuring atomically dispersed Pd‐N4 sites in ZIF‐67, demonstrates superior robustness and maximized Pd utilization, significantly ...
