Molecularly modified ultrathin Al2O3 layers as proton-conductive, oxygen-impermeable nanomembranes for catalytic surfaces

DLDalia Leon-ChaparroCEChristos EnglezosBMBastian Mei

Key Points

  • The aim is to assess the performance of ultrathin Al2O3 layers as nanomembranes in catalytic processes.
  • Characterization of ultrathin Al2O3 coatings
  • Evaluation of proton and O2 transport properties
  • Testing in photocatalytic and electrocatalytic applications
  • Enhanced proton conductivity observed in modified layers
  • Oxygen impermeability was successfully achieved
  • Improved selectivity in catalytic reactions noted with these coatings

Abstract

Ultrathin inorganic oxide coatings can improve selectivity in photo- and electrocatalysis, but they also bury active sites and impede transport of the desired reactants. Here we quantify proton and O2...
