In situ synchrotron IR study relating temperature and heating rate to surface functional group changes in biomass

Physicochemical Characterization of Wheat Straw during a Continuous Pretreatment Process

“…The FTIR band at 1167 cm −1 was associated with a glycosidic linkage of cellulose , . The FTIR bands at 2950 and 2906 cm −1 were attributed to the stretching of C–H . Kristensen et al ascribed the bands at 2950 and 2906 cm −1 to waxes that are reduced after SE.…”

“…Synchrotron radiation infrared microspectroscopy allows the in situ analysis of biomass samples at the molecular level, combining spatial and chemical information from IR absorbance to produce a chemical map that can be linked to a particular morphology or functional group . Kirtania et al explained that the beamline capacity made it possible to focus on single particles to obtain low‐noise measurements without mixing with KBr; additionally, the IR beam is not focused on any distinct particle. Thus, it measures the bulk surface functional groups, which comprise the spectral average in several particles.…”

“…Thus, it measures the bulk surface functional groups, which comprise the spectral average in several particles. To our knowledge, scarce literature is available that deals with synchrotron‐based IR beam focus in biomass analysis , . However, these studies did not apply a pretreatment process of WS for glucose production.…”

“…Yu et al presented the results of the mapping of the tissue of a wheat seed. Kirtania et al reported on an in situ study of the pyrolysis of three types of woody biomass to observe changes in the surface‐functional groups with temperature ramping by synchrotron‐based IR beam.…”

The status of the first infrared beamline at Shanghai Synchrotron Radiation Facility

“…The IR region contains a variety of characteristic marker bands that are relevant to molecular structures. IRSR has been used in several fields including life science, materials science, cultural heritage, and food science [7][8][9][10][11][12]. In recent years, many IRSR beamlines have been constructed in third-generation synchrotron facilities.…”
