Mass spectrum of the released gas near the combustion temperature of the dried gel. From this result, the reducing gases H2, CH4, and CO can be observed clearly. Inset shows the TG measurement result of the dried gel. The rapid decrease of the weight of the dried gel reveals the combustion temperature near 200°C.
