Investigation on the Adsorption and Photooxidation of Glycerol at TiO2 Nanotubular Arrays

Investigation on the Adsorption and Photooxidation of Glycerol at TiO2 Nanotubular Arrays

A study is presented on the adsorption of glycerol at TiO2 as well as on its oxidative process during the contemporary water Photoelectro-splitting for hydrogen production. A deepening in the understanding on the working mechanism of the TiO2 nanotubular photoanodes and on the interactions between g...

A deepening in the understanding on the working mechanism of the TiO2 nanotubular photoanodes and on the interactions between glycerol and these structures has been gained through photocurrent tests, voltammetric scans, and EIS analysis.
