Figure 1: XRD patterns. (a) Samples prepared using MEK and calcined at different temperatures, and (b) samples using various solvents and calcined at different temperatures. The notations T, A, and R correspond to titanate, anatase, and rutile, respectively. The reference patterns correspond to the JCPDS: number 21-1272 (anatase), number 21-1276 (rutile), number 31-1329 (sodium trititanate), and number 47–561 (hydrogen trititanate).
