Abstract : New series of Sm1-xZrxFe1-xYbxO3 (SFZYO) (x=0.0,0.1,0.3,0.5,0.7and 0.9) were synthesized using dry chemistry route. Rietveld refinement of the obtained X-ray diffraction data confirmed the materials with x = 0.0 to 0.7 crystallizes in the orthorhombic symmetry (Pbnm space group). For x = 0.9, the crystal structure changed to cubic in the Fm-3m space group. Introducing Zr and Yb into SmFeO3 crystal structure significantly improves its light absorption capacity and enhances its photocatalytic activity. Optimized Zr and Yb content with x = 0.5 showed highest photocatalytic H2 production evaluation rate(15μmol/h/g) under visible light while under UV light (70μmol/h/g), additionally high ionic conductivity of 1.465x10-2S/cm.
