Abstract
Direct, nonoxidative conversion of methane towards olefins/aromatics is a hot topic in the background of “carbon peak, carbon neutrality”, owing to zero CO2 emissions, high carbon atom utilization efficiency and hydrogen production. In the present paper, the advances of methane dehydroaromatization (MDA) and direct nonoxidative conversion of methane to olefins, aromatics, and hydrogen (MTOAH) are reviewed, based on our research works and the publications from 2018 to 2021. The determination of active sites, reaction intermediates, reaction mechanism, catalyst modification and improvement were considered. Finally, the future prospect was given for the direct nonoxidative conversion of methane to olefins/aromatics.
