Overview

Randomized trial demonstrates improved ammonia production in N−CQDs/TiO2, indicating effectiveness for NO reduction.

Key Points

  • This research aims to enhance ammonia production through the electrocatalytic reduction of nitrogen oxides using an N−CQDs/TiO2 catalyst.
  • Utilized a single-step hydrothermal approach to synthesize N−CQDs/TiO2 catalyst.
  • Conducted density functional theory computations to investigate microstructure, charge transfer, and reaction pathways.
  • Measured ammonia production rate and Faradaic efficiency under ambient conditions.
  • Achieved ammonia production rate of 4242.24 μg·h−1·mg−1 at −0.90 V vs. RHE in 0.10 M K2SO4 electrolyte.
  • Faradaic efficiency reached 88.02%, doubling the performance of unmodified TiO2.
  • Theoretical analysis suggests nitrogen doping improves charge distribution and enhances NO adsorption.
