Photocatalytic degradation of CH3Cl over a nickel-loaded layered perovskite

open access: yes, 2019
A highly donor-doped (110) layered perovskite, La2Ti2O7, was found to be an efficient photocatalyst comparable to TiO2 P25 and better than K2La2Ti3O10, the latter being an undoped (100) layered perovskite, in oxidative degradation of CH3Cl in the gas ...
