Figure 1. (A) N₂ adsorption-desorption isothermal curves conducted at 77 K for MW-ox^RT (1) and MW-ox^HT (2) along with their corresponding pore size distribution (inset); (B) TGA conducted on MW-ox^RT (1) and MW-ox^HT (2) in comparison with their pristine counterpart. Analyses conditions: from 40 to 750 °C (5 °C/min) in N₂ atmosphere (100 mL/min); (C) High-resolution O 1s XPS signal of MW-ox^RT (1) and (D) MW-ox^HT (2) along with their fitting deconvolution. TGA: Thermogravimetric analysis; XPS: X-ray photoelectron spectroscopy.
