  • A highly active anatase TiO2 catalyst for alkylation of phenol with methanol 
    Gandhe, A.R.; Naik, S.P.; Kakodkar, S.B.; Fernandes, J.B. (Catalysis Communications. 7(5); 2006; 285-288.)
    TiO2 anatase sample was synthesized by sol-gel method and was evaluated as a catalyst for vapour phase methylation of phenol. It was found to be highly active and gave over 97 percent conversion under certain experimental ...
  • A highly ortho-selective TiO2 catalyst for the methylation of phenol 
    Gandhe, A.R.; Fernandes, J.B. (Catalysis Communications. 5(2); 2004; 89-94.)
    The investigation describes alkylation of phenol with methanol over an active rutile TiO2 catalyst in relation to a commercial rutile form. The catalysts were characterized by XRD, surface areas and temperature programmed ...
  • Manganese oxide OMS-2 as an effective catalyst for total oxidation of ethyl acetate 
    Gandhe, A.R.; Rebello, J.S.; Figueiredo, J.L.; Fernandes, J.B. (Applied Catalysis B-Environmental. 72(41641); 2007; 129-135.)
    This investigation focuses mainly on the use of a synthetic cryptomelane type manganese octahedral molecular sieve, OMS-2, as a catalyst for the total oxidation of ethyl acetate. OMS-2 was found to be a highly efficient ...
  • Methylation of phenol over Degussa P25TiO(2) 
    Gandhe, A.R.; Fernandes, J.B. (Journal of Molecular Catalysis A-Chemical. 226(2); 2005; 171-177.)
    Degussa P25 TiO2 was evaluated as a catalyst for vapour phase methylation of phenol. It gave an optimum conversion of 32 percent at 450 degrees C and formed predominantly the ortho-, para- and meta-cresols. The activity ...
  • Selective synthesis of N-doped mesoporous TiO2 phases having enhanced photocatalytic activity 
    Gandhe, A.R.; Naik, S.P.; Fernandes, J.B. (Microporous and Mesoporous Materials. 87(2); 2005; 103-109.)
    This study demonstrates a simple route for synthesis of nanocrystalline N-doped titania by calcination of acidified TiCl3 in presence of urea and oxalic acid. While urea was used as a source of nitrogen, oxalic acid was ...
  • A simple method to synthesize N-doped rutile titania with enhanced photocatalytic activity in sunlight 
    Gandhe, A.R.; Fernandes, J.B. (Journal of Solid State Chemistry. 178(9); 2005; 2953-2957.)
    This study demonstrates a simple route for the synthesis of nanocrystalline N doped rutile titania by calcination of acidified TiCl3 in presence of urea. Urea was used as a source of nitrogen. The N doped rutile titania ...
  • TiO2: As a versatile catalyst for the ortho-selective methylation of phenol 
    Gandhe, A.R.; Fernandes, J.B.; Varma, S; Gupta, N.M. (Journal of Molecular Catalysis A-Chemical. 238(41641); 2005; 63-71.)
    The investigation describes synthesis of active pure and mixed phase TiO2 catalysts by a TiCl3-urea-oxalic acid precursor method. Pure and mixed phase TiO2 catalysts could be obtained by varying the concentration of oxalic ...
