Dendritic Pt thin films are electrodeposited on bulk Pt electrodes in 10×10^-3 mol·L^-1 K₂PtCl₆+3× 10^-4 mol·L^-1 PbAc₂ + 0.5 mol·L^-1 HClO₄ using square-wave potential pulses. As the deposition time increases, the length of the Pt dendrites increases from 400 to 900 nm, and the distribution density of Pt nanoparticles (~10 nm), which consist of coiled Pt dendrites, increases greatly. From hydrogen adsorption/ desorption obtained from cyclic voltammograms (CV), the surface of the dendritic Pt thin film electrodes has a relative roughness (C_r), which increases from 9 to 36 as the deposition time increases. Maximum enhanced IR absorption of adsorbed CO (CO_ad) is observed at the deposition time of 6 min. Anomalous infrared effects for CO_ad are also seen on the dendritic Pt thin film electrodes. The line shapes of CO_ad change with increasing deposition time, in order: bipolar→downward→bipolar→upward→bipolar→ downward bands. Fano-like infrared effects (bipolar), surface enhanced IR absorption (enhanced downward band), and abnormal IR effects (enhanced upward band) are highly dependent on the surface architecture of the nanostructures. The as-prepared dendritic Pt thin films provide model substrates for in-depth studies of the anomalous infrared effects of CO_ad in metal nanostructures.
