In case of PMS, the H 2 evolution was initiated at 390 °C (Fig. 2 a). The H 2 concentration sharply increased up to 0.4 mol % in the temperature range of 390−480 °C, which corresponds to the second peak (∼520 °C) observed in TGA result (Fig. 1 a). This evolution of H 2 likely resulted from dehydrogenation of short-chain (first peak) and long …
