| 1 | Effect of doping of different rare earth(europium,gadolinium,dysprosium and neodymium) metal ions on structural,optical and photocatalytic properties of LaFeO3 perovskites显示文摘Different rare earth substituted perovskites LaRExFe1-xO3(where RE=Eu3+,Gd3+,Dy3+,Nd3+and x=0.02,0.04,0.06,0.08,0.1)with orthorhombic structure and narrow band gaps were successfully fabricated via sol-gel autocombustion method.All the substituted perovskites are found to exhibit excellent photocatalytic activity towards the oxidative degradation of dye molecules.An excellent increase in the rate constant values of pure perovskite(LaFeO3)photocatalytic reactions is observed with the substitution of rare earth metal ions.Best results are obtained for LaNd0.1Fe0.9O3 which exhibits around 7 times increase in the rate constant values for degradation reaction of SO(1.76×10-1 min-1)and RBY(1.69×10-1 min-1)dyes. | Manisha Dhiman Sonal Singhal | 2019 | Journal of Rare Earths2019，37，12： | 4 |
| 2 | Traversing the advantageous role of samarium doped spinel nanoferrites for photocatalytic removal of organic pollutants显示文摘The present work reportes the pertinence of samarium(Sm) doped spinel nanoferrites as magnetically recoverable photocatalyst for the removal of organic pollutants from wastewater.Thus,a series of Sm substituted spinel nano ferrites,MSm_(x)Fe_(2-x)O_(4)(M=Ni,Co;x=0,0.02,0.06,0.1) we re synthesized via sol-gel methodology.The effect of Sm doping on the structural,morphological,optical and magnetic properties of pristine nanoferrites was investigated systematically.Further,the fabricated samples were explored as photocatalysts for the oxidative degradation of antibiotics(ofloxacin and norfloxacin) and dyes(methyl orange and safranin O).The Sm doped nanoferrites exhibit astonishing catalytic efficacy that can be attributed to higher surface area,octahedral site preference of Sm ions and reduced band gap.The synthesized nanoferrites display excellent recyclability which enables them to be utilized as potential photocatalysts for wastewater treatment. | Sneha Singh Paramdeep Kaur Vinod Kumar K.B.Tikoo Sonal Singhal | 2021 | Journal of Rare Earths2021，39，7： | 0 |
