Variations of parameters in the synthesis of AC-DS
| Stage/parameters | Stage 1: Temperature | Stage 2: Activating agent | Stage 3: Acid-washing |
|---|---|---|---|
| Variation in the parameter | 400 °C versus 600 °C | KOH versus NaOH | With versus without acid-washing (HNO3 with 50% v/v concentration) |
| Other consistent parameters | Activating agent (KOH) and washing with deionized water only | Calcination temperature (400 °C) and washing with deionized water only | Activating agent (KOH) and calcination temperature (400 °C) |
