Figure 5. (A) Correlation between the B/N ratio, BOx content obtained from XPS and the reaction rate of CBN and CBN-Zx in ODHP; (B) The schematic diagram of BOx species generation from B-terminated defects in ODHP. BOx: Boron oxygen; XPS: X-ray photoelectron spectra; CBN: carbon-doped boron nitride; CBN-Zx: ZIF-8 derived carbon-doped boron nitride; ODHP: oxidative dehydrogenation of propane.
