The synthesis of SrTiO3 hollow sphere built as assembly of nanocubes using cetyltrimethylammonium bromide (CTAB) as capping agent was aimed to control the size and shape of the particles. The condition of the synthesis at 220 °C for 48 hours with a molar ratio of Sr:Ti was 1:1.25 and starting material:CTAB was 1:0.5, have resulted the particles with a high crystallinity with specific XRD peaks at 2θ; 32.41 (110), which was in agreement with the cube-perovskite structure. The refinement of the crystal structure by the Rietveld method showed that the crystal structure of the measurement results has a high match with the result of the calculation with Rwp value was 12.07. The interaction between CTAB and the surface of SrTiO3 traced in the FTIR spectrum with wave number 1100-1250 cm-1 indicated the stretching vibration of C-N was weakened due to the capping process. SEM images showed the particles with hollow microsphere, while TEM images revealed that the hollow particles were assembled by nanocubes with an average size of 20 nm. © 2019, State Islamic University Syarif Hidayatullah Jakarta, Faculty of Science and Technology, Department of Chemistry.
