Enhanced photoelectrochemical performance of iron and carbon self-doped TiO2 photoanodes modified with nitrogen

The photoelectrochemical performance and the semiconducting properties of iron, carbon and nitrogen modified TiO2 films prepared by a sol-gel method and deposited on 304 stainless steel (304SS) plates by a dip-coating technique were studied. Iron and carbon co-doped films were pr...

Effect of Metal Substrate on Photo(electro)catalytic Activity of B-Doped Graphene Modified TiO2 Thin Films: Role of Iron Oxide Nanoparticles at Grain Boundaries of TiO2

TiO2 thin films deposited on stainless steel (SS) substrates exhibit low photocatalytic (PC) activity when calcined above 350 °C. The cause is the presence of Fe3+ into the film due to its diffusion from SS to the surface during the calcination process. Over the past two decades,...
