General description

2-Propanol (Isopropanol) is a secondary alcohol. It has been tested as a substitute to fuel for use in various fuel cells. CuO powder dissolved in 2-propanol has been used for the laser ablation assisted synthesis of Cu colloids. Suspension of 2-propanol with Zn(NO3)2 has been employed for the fabrication of titanium dioxide-coated stainless steel (P25-TiO2/SS) photoanode coated with uniformly thick layer of P25-TiO2.This photoanode was used for the electrochemical photocatalytic (ECPC) degradation process.

Application

2-Propanol may be employed as fuel in the polymer electrolyte membrane direct 2-propanol fuel cell.
