Overview

Randomized trial investigates radical generation pathways in methane photooxidation using different Pd catalysts, suggesting enhanced efficiency with nanoparticles.

Key Points

  • This research aims to compare the efficiency of Pd nanoparticles versus single atoms supported on CuTi-LDH in methane photooxidation.
  • Synthesis of Pd nanoparticle-supported CuTi-LDH and Pd single atom-supported CuTi-LDH catalysts.
  • Evaluation of C1 product yields and selectivity through photocatalytic methane conversion experiments.
  • Mechanistic studies using in situ XAFS and radical kinetic analyses to determine charge transfer behaviors.
  • Pd NPs-CuTi-LDH achieved a C1 liquid-oxygenates yield of 7220.7 µmol g−1 h−1, threefold higher than Pd1-CuTi-LDH.
  • Selectivity for liquid products reached 99.7% with Pd NPs-CuTi-LDH.
  • The formation energies for ·OH and ·OOH radicals were lower in Pd NPs-CuTi-LDH, facilitating more effective methane conversion.
