Photocatalytic activity of Zr:SrTiO3 under UV illumination

Novel (Na, K)TaO3 single crystal nanocubes: Molten salt synthesis, invariable energy level doping and excellent photocatalytic performance

“…[22][23][24][25] Unfortunately, shortcomings such as poor solar efficiency hinder its extensive application, and therefore, further development of the photocatalytic materials for water decomposition is indispensable. From another point of view, many of the effective photocatalysts are perovskite-like compounds, such as NaTaO 3 , 5,26 KTaO 3 , 27 SrTiO 3 [28][29][30] and Sr 2 M 2 O 7 (M ¼ Nb, Ta). 31 Among these active materials, tantalates exhibit high photocatalytic performances because tantalates possess conduction bands consisting of a Ta5d orbital located at a more negative position than that of titanates (Ti3d), which have conduction bands at a high potential, so a variety of mixed metal oxides containing closed-shell Ta 5+ transition-metal ions have been studied recently.…”

Single‐Crystal‐like Mesoporous SrTiO3 Spheres with Enhanced Photocatalytic Performance

“…Strontium titanate, SrTiO 3 , a typical cubic‐perovskite‐type multimetallic oxide with a band gap of 3.2 eV, has been considered to be a promising photocatalyst to split water into H 2 and O 2 , 16–22 and to degrade pollutant, 23–30 owing to its extraordinary physical and chemical properties such as excellent thermal stability, photocorrosion resistibility, and good structural stability as the host for metal ion doping. Accordingly, the successful synthesis of mesoporous SrTiO 3 structures with high crystallinity will potentially enhance its photocatalytic performance, because the unique porous motif and large surface‐to‐volume ratio will enhance exchange with a second phase or the environment.…”

Preparation and Study of ZnAl2O4/CeO2 Water Remediation Photocatalyst and Its Photocatalytic Activity

“…Using semiconductor photocatalyst to degrade organic dyes in wastewater before discharging it into rivers will greatly reduce environmental pollution [7,8]. Currently, commonly used semiconductor photocatalysts are TiO 2 and SrTiO 3 , but these single component photocatalysts can only respond to ultraviolet light and cannot effectively utilize sunlight [9][10][11].…”
