Fig. 4: Calculated activation barrier for Pt nanorod on TiO2(110) compared with Pt(111).
From: Controlling hot electron flux and catalytic selectivity with nanoscale metal-oxide interfaces
Optimized free-energy profiles for a methyl formate and b the CO2 formation path with reaction barriers (ΔG‡). Barriers with red and blue indicate the RDS of each path for Pt nanorod structure on TiO2(110) and Pt(111), respectively. c Schematic drawing showing formation of CO2 and methyl formate in methanol oxidation on Pt nanorod/TiO2(110). Species marked with an asterisk (*) are adsorbed on the surface. The gray, blue, brown, red, and yellow balls indicate Pt, Ti, C, O, and H, respectively.
