| Sample | Kind of method | Composition | Reaction time | Structure | 
|---|---|---|---|---|
| S1 | sonochemical | Cd(NO3)2 + TAA (1:2) | 40 min | cubic | 
| S2 | sonochemical | Cd(NO3)2 + Na2S (1:2) | 40 min | cubic | 
| S3 | combined sonochemical-solvothermal | Cd(NO3)2+ TAA (1:2) | 40 min | hexagonal (irregular) | 
| S4 | combined sonochemical-solvothermal | Cd(NO3)2+ TAA (1:4) | 1 h | hexagonal (irregular) | 
| S5 | combined sonochemical-solvothermal | Cd(NO3 )2 + Na2S(1:4) | 1 h | hexagonal (irregular) | 
| S6 | combined sonochemical-solvothermal | Cd(NO3)2 + Na2S (1:4) | 5 h | hexagonal |
