The amount of carbon in the chitin reactant was determined with an elemental analyzer (PerkinElmer 2400 II).
The X‐ray diffraction (XRD) patterns of the catalysts and the reactants were measured on a Rigaku SmartLab XRD system with Cu Kα radiation in the 2θ range of 5–90°.
Thermogravimetry‐differential thermal analysis (TG‐DTA) of the catalysts after the reaction was carried out on a Thermo plus EVO2 TG‐DTA8122 (Rigaku) instrument at a heating rate of 10 K min−1 in flowing dry air. During TG analysis, real‐time images of the samples were recorded with the optional direct monitoring system of the TG‐DTA instrument.
The concentration of magnesium species in the liquid fraction was determined by means of inductively coupled plasma atomic emission spectrometry (SPS4000, SII NanoTechnology).
