Development and Characterization on the Isothermal Kinetics of Mg(OH)₂-sol Synthesized by Chemical Method

Mg–O–F Nanocomposite Catalysts Defend against Global Warming via the Efficient, Dynamic, and Rapid Capture of CO2 at Different Temperatures under Ambient Pressure

“…This step is followed by another weight loss at approximately 270 °C, which is ascribed to the dehydroxylation of Mg(OH) 2 . , At 400 °C, the calculated mass loss was 34.5%, whereas at 500 °C, it was 37.7%. Due to the liberation of physically adsorbed water molecules associated with Mg(OH) 2 , these values exceeded the theoretical value − for the conversion of anhydrous Mg(OH) 2 to MgO (ca. 30.86%), as presented in eq : normalM normalg false( OH false) 2 → normalM normalg normalO + normalH 2 normalO on the other hand, NH 4 F·HF undergoes melting at 125 °C, followed by a subsequent fast step due to its decomposition around 150 °C, as shown in eq : normalN normalH 4 normalF · normalH normalF → normalN normalH 3 + 2 normalH normalF the TG profiles of the mixed samples can be divided into four temperature zones, as shown in Figure .…”
