Thesis (Ph.D.)--Stanford University, 2023.

This doctoral thesis is focused on investigating electrochemical sustainable technologies using renewable feedstocks to meet the increasing energy demand as well as the zeroemission goals. Complemented with theoretical approach, we focused on the benzyl alcohol oxidation (BAO) reaction and the oxygen reduction reaction (ORR) to shed light on the fields of biomass upgrading and fuel cell applications with specific focuses on mechanistic insight, microenvironment effect, electrochemical performance, and material evolution.The BAO reaction serves as a cornerstone in biomass valorization. Diving into the fundamentals, our work highlighted how different microenvironments and material changes, especially in the presence of contaminants, affected catalytic performance. By employing advanced computational techniques such as density functional theory (DFT), a step-by-step model was constructed to unravel the redox mechanism and the introduced vacancy-driven mechanism, adding another layer of understanding to the possible mechanisms that can take place on transition metal-based surfaces.Transitioning to ORR, our research spotlighted the potential of nitrogen-doped carbons with structural advantages, casting them as promising electrocatalysts. Moreover, we also dived into the novel M-N4 moiety found in single-atom catalysts (SACs) and metal-organic frameworks (MOFs). Coupled with theoretical modeling, our work establishes structureactivity relationships between the material property and the electrochemical performance, as well as offering insights into the in-situ material degradation mechanisms.Together, this dual-themed thesis provides a holistic view of sustainable biomass upgrading and fuel cell applications, developing fundamental understanding of the reaction and the catalysts, opening doors for designing next-generation materials, and pushing the boundaries of green and sustainable development.
