increased with increasing reaction time at X < 0.05, then there is a slow variation at the
conversion range from 0.05 to 0.35, and finally slowly decreased. It demonstrates that
a transaction mechanism of the reaction exit at X is approximately 0.11. To understand
the transaction process, a series of the detected experiment were explored using an
XRD, SEM/EDS, and optical microscope. Table 2 illustrates the different cases for
detection.
