Molecularly modified ultrathin Al2O3 layers as proton-conductive, oxygen-impermeable nanomembranes for catalytic surfaces
{{output}}
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 permeability of 3-5 nm amorphous alumina (Al2O3) overlayers... ...
