Overview

Randomized trial evaluates Pd NPs on CuTi‐LDH for methane conversion, indicating improved yields and selectivity.

Key Points

  • The aim is to compare Pd nanoparticles and single atoms on CuTi‐LDH for efficient methane conversion.
  • Synthesize Pd nanoparticle‐supported CuTi layered double hydroxide (Pd NPs‐CuTi‐LDH) and single atom (Pd 1‐CuTi‐LDH) catalysts.
  • Conduct photocatalytic tests to measure C 1 liquid products yield and selectivity.
  • Utilize in situ XAFS analyses and radical kinetic evaluations to investigate charge‐transfer behavior.
  • Pd NPs‐CuTi‐LDH achieves a high C 1 liquid‐oxygenates yield of 7220.7 µmol g −1 h −1, tripling the yield of Pd 1‐CuTi‐LDH.
  • Selectivity remains high at 99.7% for Pd NPs‐CuTi‐LDH.
  • Distinct charge transfer behavior results in ·OH radicals largely from H 2 O on Pd NPs‐CuTi‐LDH versus O 2 on Pd 1‐CuTi‐LDH.
