Overview

This research shows an innovative Ag-Cu catalyst improves nitrate reduction in wastewater, indicating enhanced reaction selectivity.

Key Points

  • Achieving 98% ammonia selectivity, the Ag-Cu catalyst showcases remarkable efficiency under visible light.
  • The production rate of 630.5 µmol h−1 g−1 highlights the effectiveness of the spatially decoupled catalytic sites.
  • The study uses in situ spectroscopic studies and theoretical calculations to validate the tandem reaction mechanism.
  • This innovative design could solve selectivity issues in complex multi-proton/electron reactions in wastewater treatment.
