主 题：polyhedral SrTiO3 hydrothermal synthesis low temperature photocurrent property photocatalytic activity stability
摘 要：SrTiO3 nanoparticle (NP) photocatalyst was synthesized with a facile and environmentalfriendly hydrothermal method using tetrabutyltitanate,strontium oxide,and ethanolamine as precursors at low temperature without alkali as mineralizer for the first *** SrTiO3 nanoparticles were characterized by X-ray diffraction (XRD),transmission electron microscopy (TEM),field emission scanning electron microscopy (FESEM),and N2 Brunauer-Emmett-Teller (BET) *** SrTiO3 catalyst synthesized at 120 ℃ (STO-120) exhibited the highest photocurrent intensity among the samples synthesized at different hydrothermal *** high photocatalytic performance of STO-120 was mainly attributed to the more homogeneous and minimum nanoparticle size,the highest surface area,and the maximum light absorption property among the four different *** work presented an applicable and facile method to fabricate a highly active and stable SrTiO3 photocatalyst for organic pollutant degradation.
