Can this method be applied with metal salts of sulfate or chloride or acetate?
Dear Rana,
Usually the Pechini's method must be denomined as polymeric precursor method. For example, if you wish to synthesize successfully ZnO nanostructures, you can use chloride, acetate or even oxide as Zn precursor.
Thanks Sir
as you have mentioned that Pechini method is a polymeric method so if we are not using polymer like EG or PEG, then the process will be sol gel combustion in that case will acetate be helpful because in solgel combustion metal salt act as a oxidizer in that situation will acetate be suitable for the reaction to proceed with the fuel (citric acid or urea etc.)
Pechini method is based on the formation of metallic complexes with carboxylic acids followed by a polycondensation reaction with polyalcohols like EG or PEG. In urea-modified Pechini method(UmPM), two phenomenon occur: certain degree of control over pH variation & urea obstructs the formation of bridged bonds with the carboxylic acid.. so generally in UmPM you will get less agglomerated nano-particles with a fair degree of uniformity in size. Pechini method works fine with any alkoxides or acetates.
