At eye level: The high CH bond strength of ethane challenges the stability of metal‐free carbon nanotubes (CNTs) as a catalyst for oxidative dehydrogenation (ODH). However, surface modification of the CNTs with B 2 O 3 or P 2 O 5 leads to drastically enhanced oxidation resistance of the catalysts during ODH and increases alkene selectivity due to the suppression of electrophilic oxygen intermediates on the carbon surface.
