Synthesis and Structure of an Ion‐Exchanged SrTiO₃ Photocatalyst with Improved Reactivity for Hydrogen Evolution

Abstract

This has motivated attempts to develop photocatalysts with enhanced charge-separation properties using defect engineering, [5,6] facet engineering, [7][8][9] and the construction of heterojunctions. [10][11][12] Recently, molten salt treatments have been used for synthesis and to optimize photocatalyst properties. [13,14] In a molten salt, the mass transfer between precursors is accelerated and, compared with conventional solid-state synthesis, lower reaction temperatures can be used. [15,16]

Review of First Principles Simulations of STO/BTO, STO/PTO, and SZO/PZO (001) Heterostructures

“…STO is a typical ABO 3 perovskite crystal with high photocatalytic activity and excellent electronic properties. It has numerous applications in electronics, sensors, catalysts, and energy storage devices [32][33][34]. PZO perovskite has been frequently mentioned in connection with energy storage performance [35][36][37].…”

Effect of dislocations on carrier recombination and photoelectrochemical activity in polished and unpolished TiO2 and SrTiO3 crystals

“…Strontium titanate (SrTiO 3 ) is a cubic perovskite oxide with a bandgap of 3.2 eV and exhibits promising photocatalytic activity in water-splitting reactions. [12][13][14][15][16] In recent decades, powder or nanoscale crystallite forms of TiO 2 [17][18][19][20][21][22][23] and SrTiO 3 [24][25][26][27][28][29][30] have been extensively investigated and have displayed promising photocatalytic performances. These powder and nanocrystalline structures increase the contact area with the solution and the area exposed to solar light; theoretically, PEC activity is also expected to be enhanced with these structures.…”
