A Comparison of Different A-, A-B-, and B-Site Incorporated in (Ba_0.5Sr_0.5)TiO₃ on Photocatalytic Application

Table 1

Phase structure, crystallite size, and lattice parameters of BST and the structural modified BST catalysts.

Sample	Phase	Crystalline size  (nm)	Lattice parameter (nm)^1
			BST	Cubic	30	0.3954	—	—
A-BST	Tetragonal	30	0.3931	0.3946	1.004
A-B-BST	Cubic	28	0.3941	—	—
B-BST	Cubic	27	0.3941	—	—

The cubic phase was calculated from Bragg’s law using the diffraction peaks of () so the tetragonal phase uses the diffraction peaks of () and ().
