Abstract A novel two-step sol–gel method was used i
order to synthesize PbTiO3 nanoparticles with aid of
Pb(CH3COO)22H2O, and Ti(OC4H9)4 (TNBT) as the
starting reagents in the presence of ethanol as the solvent.
To the best of authors knowledge, it is first time that
benzene-1,3,5-tricarboxylic acid [C6H3(COOH)3] (trimesic
acid) use as a chelate agent in produce lead titanate
nanoparticles. Besides, to examine the effect of some
reaction parameters such as surfactants, reaction temperature,
and molar ratio of TNBT to trimesic acid on the
morphology and chemical structure of final products several
tests were performed. The as-synthesized PbTiO3
nanoparticle was utilized as photo-anode material for the
fabrication of FTO/PbTiO3/CdS/Pt–FTO and photocatalyst
for decolonization of rhodamine-B (RhB) and methylene
blue (MB) to investigation its light harvesting applications.
Furthermore, according to the XRD results, only in the
presence of trimesic acid as the chelate agent pure PbTiO3
nanoparticle was synthesized. The photocatalyst results
reveal that the maximum decolorization of 88 and 82 % for
RhB and MB occurred with PbTiO3 nanoparticles catalyst
in 40 min of stirring under ultraviolet light irradiation,
respectively.
