biostudies-literatureUnknown13(35)Li XBaTiO₃/CeO₂ nanoparticles with heterogeneous structure were successfully synthesized <i>via</i> a gel-assisted hydrothermal method. The molar ratio of Ti/Ce was set as 1 : 0, 0.925 : 0.075, 0.9 : 0.1; 0.875 : 0.125, and 0.85 : 0.15 in the dried gels. Affected by the values of Ti/Ce, the particle sizes of hydrothermal products decreased obviously, and the surface of nanoparticles became rough and even had small protrusions. XRD, SEM, HRTEM, XPS, DRS, ESR, and PFM were used to characterize the nanoparticle textures. We speculated that the main body and surface of nanoparticles were BaTiO₃ and CeO₂ protrusions, respectively. The catalytic performance of BaTiO₃/CeO₂ nanoparticles was characterized by their abilities to degrade RRSC advances24583-24593https://www.ebi.ac.uk/biostudies/studies/S-EPMC10427892biostudies-literaturePiezo-photocatalytic properties of BaTiO₃/CeO₂ nanoparticles with heterogeneous structure synthesized by a gel-assisted hydrothermal method.PMC10427892Li XLi HLiu JYan KZheng HZhu KWang JDang FfalsePiezo-photocatalytic properties of BaTiO₃/CeO₂ nanoparticles with heterogeneous structure synthesized by a gel-assisted hydrothermal method.BaTiO₃/CeO₂ nanoparticles with heterogeneous structure were successfully synthesized <i>via</i> a gel-assisted hydrothermal method.
