“…The peaks at 585-523 cm −1 repr the Ti-O-Ti stretching vibrations, and the peaks at 720-713 cm −1 indicate the presen Pb-O-Ti bonds. These spectra can possibly confirm the presence of both PTO and Ti the PTO/TO composites [33].…”

Photocatalytic dye degradation is an energy-saving, environmentally friendly and sustainable way of managing potentially toxic wastewater from the textile industry. PbTiO3 was prepared using a solid-state reaction method, and an optimal ratio of PbTiO3/TiO2/g-C3N4 photocatalyst was synthesized using the sol-gel method to test its ability to decompose organic dyes. Methylene blue (MB) was selected as a target dye to test the photocatalytic effects. SEM results showed that the synthesis of a PbTiO3/TiO2/g-C3N4 photocatalyst yielded a unique nano structure with many surface pores. UV-Vis analysis demonstrated that the novel composite photocatalyst had higher visible light absorption, and a reduced energy gap. Experimental results showed that of the samples tested, PTO/TO/CN 1.0 showed the best photocatalytic effect on the removal of MB. Under visible light, the removal rate of MB by PTO/TO/CN 1.0 was up to 98.79%. The novel PTO/TO/CN 1.0 photocatalyst exhibited relatively high MB adsorption and had a high photocatalytic ability.

“…Furthermore, in the 1000 °C sintered PTO sample, due to the formation of Pb-O-Ti bonds, a new peak formed at approximately 711 cm −1 . The aforesaid indicates successful chemical bonding between the TiO2 and PbO, forming the Pb-O-Ti bond[33].…”
