In this paper, LaBO3 perovskite type catalyst formulations were prepared by sol-gel auto combustion method using citric acid as the fuel. Activity of catalysts was tested in catalytic oxidation of toluene as a model of volatile organic compounds. LaCoO3 perovskite formulation showed the highest activity among LaBO3 (Fe, Mn and Co) perovskite catalysts. So, LaCoO3 perovskite based catalyst was s...

Apart from the energy gap law, control parameters over nonradiative transitions are so far only scarcely regarded. In this work, impact of both covalence lanthanoid–ligand bond and varying distance on magnitude intrinsic decay rate between excited 6P5/2 6P7/2 spin–orbit levels Gd3+ is investigated in chemically related compounds Y2[B2(SO4)6] LaBO3. Analysis temperature-dependent luminescence sp...
