Correlative Effects of Carbon Support Structures and Surface Properties on ORR Catalytic Activities of Loaded Catalysts.
ACS Appl Mater Interfaces
September 2024
As a complex three-phase heterogeneous catalyst, the oxygen reduction reaction (ORR) catalyst activity is determined by the interfacial and surface structures and chemical state of the catalyst support. As a typical biomass carbon-based support, rice husk-based porous carbon (RHPC) has natural unique hierarchical porous structures, which easily regulate the microstructure and surface properties. This study explored the correlative effects of RHPC structure and surface properties on ORR catalytic activity through the typical modification methods, namely, alkali etching, high temperature, oxidation, and ball milling.

- Two-dimensional covalent organic frameworks (COFs) and their derivatives are effective electrocatalysts due to their unique structures and high surface area.
- This study explores creating a non-stable Pt-N coordination site by electrochemically modifying platinum atoms in a 2D COF to serve as an efficient, conductive catalyst for the hydrogen evolution reaction (HER).
- Findings demonstrate that the nitrogen-rich COF not only improves the interaction between platinum and hydrogen intermediates but also boosts electron transport and stability in acidic conditions.
