Area of Science:

  • Electrochemistry
  • Materials Science
  • Catalysis

Background:

  • Urea oxidation reactions (UORs) are crucial for energy conversion but face challenges in C─N bond cleavage and intermediate desorption.
  • Nickel-based catalysts are promising for UORs but require optimization for efficiency and durability.
  • Metal-organic frameworks (MOFs) offer tunable structures for catalytic applications.

Purpose of the Study:

  • To develop a novel interfacial coordination assembly protocol for modifying Ni-based MOFs for enhanced UOR electrocatalysis.
  • To investigate the mechanism by which Co-PA modification improves urea oxidation performance.
  • To achieve boosted and sustained UOR electrocatalysis with improved durability and resistance to CO2 poisoning.

Main Methods:

  • Fabrication of Co-PA modified Ni-BDC MOF nanosheet arrays (CC/Ni-BDC@Co-PA).
  • Electrochemical characterization including cyclic voltammetry, linear sweep voltammetry, and electrochemical impedance spectroscopy.
  • In situ characterization and theoretical calculations (e.g., DFT) to understand electronic structure and reaction mechanisms.

Main Results:

  • Surface Co-PA modification effectively altered the electronic state of Ni sites, promoting urea adsorption and C─N bond cleavage.
  • The modified catalyst exhibited enhanced hydrophilicity and aerophobicity, weakening *COO adsorption and promoting CO2 desorption.
  • CC/Ni-BDC@Co-PA demonstrated ultralow potential (1.300 V vs RHE at 10 mA cm-2), a low Tafel slope (45 mV dec-1), and excellent durability, mitigating CO2 poisoning.

Conclusions:

  • The interfacial coordination assembly of Co-PA on Ni-BDC MOFs is a highly effective strategy for boosting UOR electrocatalysis.
  • Surface engineering with metal-phytate complexes can overcome key challenges in UORs, including intermediate desorption and catalyst poisoning.
  • This work presents a novel paradigm for designing advanced MOF-based electrocatalysts for efficient and durable energy conversion applications.
