- 요약This thesis explores the design, synthesis, and application of molecularly defined single-site heterogeneous catalysts (SSHCs) supported on carbon materials. Motivated by the broad reactivity and stability of activated carbon supported catalyst, AC/MoO2, the initial focus was the development of true single-site fullerenol-supported molybdenum dioxo catalyst, Ful/MoO2, which enabled characterization of isolated and well-defined Mo(VI) sites via XAS, XPS, DRIFTS, Raman, ICP, NMR, and DFT, and revealed enhanced catalytic performance and high recyclability in olefin epoxidation reactions. The catalyst platform was further expanded to tungsten, yielding AC/WO2, which showed superior selectivity for alcohol dehydration reactions and highlighted metal effects. AC/MoO2 was also applied to green plastic recycling, effectively depolymerizing polyurethanes under solvent-free conditions with high selectivity and recyclability. Ongoing work includes aerobic PET deconstruction and real-time single-molecule imaging of catalytic intermediates using SMART-EM. Together, these studies demonstrate how precision in support and metal center design can unlock new mechanistic insight and enable sustainable catalytic processes for chemical transformations.
