Novel sol–gel method for synthesis of PbTiO3 and its light harvesting applications

Abstract

A novel two-step sol-gel method was used in order to synthesize PbTiO 3 nanoparticles with aid of Pb(CH 3 COO) 2 Á2H 2 O, and Ti(OC 4 H 9 ) 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 [C 6 H 3 (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 PbTiO 3 nanoparticle was utilized as photo-anode material for the fabrication of FTO/PbTiO 3 /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 PbTiO 3 nanoparticle was synthesized. The photocatalyst results reveal that the maximum decolorization of 88 and 82 % for RhB and MB occurred with PbTiO 3 nanoparticles catalyst in 40 min of stirring under ultraviolet light irradiation, respectively.

Synthesis and Supercapacitor Application of Cerium Tungstate Nanostructure

“…Figure a (the untreated sample) contains three wide absorption bands at around 847.58, 1628.59 and 3445.16 cm −1 , while with the calcinated sample (Fiure 3b) these bands were weakened, indicating the evaporation of adsorbed water . The calcinated sample further contains band corresponding to the scheleete type structure between 950 and 460 cm −1 (950.0, 862.1, 738.2, 694.6, 481.1, 458.8, 417.2) …”

“…150 In another study, Nasab et al have also used trisemic acid as a chelating agent in the sol−gel synthesis of PbTiO 3 . 151 Doggali and co-workers have synthesized A-site K + , Ce 4+ , and Ba 2+ substituted PrMnO 3 by using the sol−gel technique and found that the surface area of thus obtained perovskites was entirely dependent on the nature of the substituting cation. 152…”

Influence of deposition temperature on the optical, structural, morphological, compositional and photoelectrochemical properties of TiO2 thin films

“…The PEC cell was a two electrode system, TiO 2 is a working electrode with active surface area of 1 cm 2 , Graphite as a counter electrode and 0.1 M NaOH was used as an electrolyte illuminated by 5 mW/cm 2 intensity UV source [29].…”
