Table 1

Crystalline and porous properties of CdIn₂S₄ prepared at different temperatures.

Temperature (°C)	𝑑^a (nm)	Pore size^b (nm)	Surface area^c (m^2g^−1)	Pore volume^d (cm^3g^−1)
500	5.4	13.5	36.1	0.15
600	8.4	13.5	34.5	0.15
700	14.2	13.6	33.5	0.15

^a𝑑 values of the samples estimated by Scherrer formula; ^bBJH pore sizes determined from the nitrogen desorption branches; ^cBET surface areas determined from the nitrogen adsorption and desorption isotherm measurement; ^dpore volumes is the BJH desorption cumulative pore volume of pores.
