From: Controlling hot electron flux and catalytic selectivity with nanoscale metal-oxide interfaces
SEM images of a Pt nanowires/TiO2 with a width of 15 nm, b Pt nanowires/TiO2 with a width of 20 nm, and c Pt nanowires/TiO2 with a width of 50 nm. Scale bars are 200 nm. d Selectivity to methyl formate under methanol oxidation on the Schottky nanodiodes at different temperatures with different widths. e Chemicurrent yield for methanol oxidation on the catalytic nanodiodes of width 15 (Pt nanowires/TiO2 with a width of 15 nm), width 20 (Pt nanowires/TiO2 with a width of 20 nm), width 50 (Pt nanowires/TiO2 with a width of 50 nm), and Pt film (Pt film/TiO2) measured both at 333 and 343 K. All results were obtained under methanol 4 Torr and O2 to 760 Torr.
