Atomic Insights into Robust Pt-PdO Interfacial Site-Boosted Hydrogen Generation
(Peer reviewed; Journal article, 2020)Suppression of catalyst deactivation without compromising activity has been a long-standing yet elusive goal in heterogeneous catalysis. Herein, we report a remarkable achievement of both hydrogen generation activity and ... -
Beyond the Reverse Horiuti–Polanyi Mechanism in Propane Dehydrogenation over Pt Catalysts.
(Peer reviewed; Journal article, 2020)The catalytic dehydrogenation of light alkanes over Pt catalysts is generally accepted to follow a reverse Horiuti–Polanyi mechanism. Using a microkinetic analysis in combination with results from density functional theory ... -
Charge-Tuned CO Activation over a χ‑Fe5C2 Fischer−Tropsch Catalyst
(Journal article; Peer reviewed, 2018)We performed DFT calculations to understand CO activation over a χ-Fe5C2 Fischer–Tropsch catalyst. The χ-Fe5C2 catalyst exhibits unique CO activation behaviors, and the BEP relation is nearly valid for this system. The ... -
Critical review of catalysis for ethylene oxychlorination
(Peer reviewed; Journal article, 2020)Ethylene oxychlorination is the key technology in vinyl chloride (VCM, the monomer of PVC, polyvinyl chloride) production to close the chlorine loop by consuming the HCl released from the former cracking step. Due to the ... -
Effects of Oxygen Mobility in La-Fe-Based Perovskites on the Catalytic Activity and Selectivity of Methane Oxidation
(Peer reviewed; Journal article, 2020)The mechanism and structure requirements of selective and total oxidation of methane in a chemical looping process are both experimentally and theoretically examined on La1–xSrxFeO3−δ (x = 0, 0.2, and 0.5) and La0.5Sr0.5 ... -
