The thermal stability of the potassium metal catalyst supported by activated carbon / Nor Ain Natasya Aziz

A material is thermally stable if a substance doesn’t break down when heated up. The thermal stability of a substance can be determined using a thermogravimetric analyser (TGA). Catalyst is a substance that initiates and increases a chemical reaction without changing the reaction itself. Due to high...
