This work focuses on the solar photocatalytic degradation of phenol using nanosized ZnO and α-Fe2O3 synthesized via precipitation route. The synthesized ZnO and α-Fe2O3 were characterized using XRD, UV/Vis and surface area analysis. α-Fe2O3 was found to exhibit better solar photocatalytic activity than ZnO under identical experimental conditions due to the larger surface area and low band gap of α-Fe2O3. The photocatalytic degradation of phenol follows pseudo-first order kinetics on both ZnO and α-Fe2O3. Key words: Photocatalysis, solar, phenol, ZnO, α-Fe2O3.
