Figure 1. (A) XRD patterns, (B) FTIR spectra, (C) UV-Vis DRS of h-BN, CBN and CBN-Zx catalysts. TEM images of (D) CBN, (E) CBN-Z0.2 and (F) CBN-Z0.4, respectively. XRD: X-ray diffraction; FTIR: Fourier transform infrared spectroscopy; UV-Vis DRS: ultraviolet-visible diffuse reflectance spectra; h-BN: hexagonal boron nitride; CBN: carbon-doped boron nitride; CBN-Zx: ZIF-8 derived carbon-doped boron nitride; TEM: transmission electron microscope.
