Supplementary Material

Supplementary Material: The FT-IR of RHNH3SO4H before and after the pyridine adsorption test. The pyridine adsorption study of RHNH3SO4H was obtained in the region of 1700–1400 cm−1. By comparing the two FT-IR spectra, after and before the pyridine test, two new bands in the regions 1544 cm−1 and 1489 cm−1 have been observed. These two bands indicated the presence of Brønsted acid sites on the catalyst.
