摘要

Secondary ion mass spectrometry combined with isotopic labeling has been applied to study the interaction of potassium carbonate (K2C18O3) with carbon black (13C) at 300-1500 K. The SIMS analysis shows that K2CO3 decomposes above 800 K to form K2O, which subsequently decomposes at 1070 K. A K2O surface species was identified by SIMS at all the temperatures studied. The presence of K2O before K2CO3 thermally decomposes is attributed to the presence of H2O in the original sample, and a model is presented to explain K2O formation.
