【Abstract】 The thermostability and acidity of heteropolyacids supported on activated carbon were investigated. The experiments demonstrated that the thermostability of heteropolyacids supported on carbon can be enhanced in accordance with the interaction between heteropolyacids and carbon sruface. The stability of some heteropolyacids on the carbon was raised 200 K more than their crystal decomposition temperature.The stronger the interaction between heteropolyacid and carbon surface, the higher the thermostability of heteropolyacid is, but the acidity is weaker.更多还原
