“…TiO 2 exists in three crystal forms: anatase, rutile, and brookite. Among these, the anatase variety exhibits a small energy gap of 3.2 eV, and has a smaller grain size which can enhance dye loading [22,23]. The selective epitaxial growth of overlapping TiO 2 on the cathode is a technique that reduces (or in some cases eliminates) the barrier of PbTiO 3 , decreasing the energy gap of the photocatalyst and enhancing visible light absorption [24].…”

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.
