Templated by TiO2 microspheres, litchi‐like SrTiO3 crystals with a narrow size distribution and monodispersity were synthesized through the combination of regulating the ethylene glycol concentration during the hydrothermal process and the post heat treatment. The results show that when the volume ratio of water and ethylene glycol reached 10:70, microsized SrCO3 was firstly formed under the hydrothermal process, and then the litchi‐like SrTiO3 powder was obtained after the postheat treatment at 700°C for 4 hours, which shows a large specific surface area of 37.41 m2/g. It is found that the concentration of ethylene glycol aqueous solution plays an important role on the morphology of the SrTiO3 crystals, and the slightly higher viscosity and proper amount of OH hydroxyl groups facilitate the formation of the micrometer spherical hierarchical surface.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
