The synergetic effect of lanthanide (La and Ce) and N co-doping of ZnO NPs for high-rate photocatalytic phenol degradation.

Simultaneously, lanthanide and N-modified ZnO NPs were synthesized and applied for the photocatalytic phenol degradation under LED irradiation. Among La and Ce, Ce-doped ZnO exhibited more efficiently photocatalytic activity. XRD analysis confirmed that most of Ce was oxidized to CeO/CeO over the photocatalyst surface as a secondary phase.

Modification of photocatalytic property of BaTiO perovskite structure by FeO nanoparticles for CO reduction in gas phase.

In this work, perovskite structure of BaTiO was coupled with FeO in different molar ratios achieving the best photocatalytic performance of CO reduction in the presence of CH as reducing agent; both of them are main greenhouse gases. The photocatalysts were synthesized by facile hydrothermal method. The samples were characterized by XRD, FTIR, FESEM, EDX, UV-Vis DRS, and photoluminescence (PL) analyses.
