These results are in agreement with the 1H NMR analysis and with the suggested role of the ligninolytic system leading to HA degradation. 展开 关键词: Phanerochaete Magnetic Resonance Spectroscopy Soil Microbiology Biodegradation, Environmental Mass Spectrometry Humic Substances Trametes Fourier Analysis ...

Chemicals Aqueous PBS stock solution and hydrogen peroxide (H2O2) (30 wt%, Cat. #H325) were purchased from Thermo Scientific (Waltham, MA, USA). We purged PBS with N2for 1 hour before any dilution and measurement. Peroxynitrite (ONOO−) was purchased from EMD Millipore Co. (Cat. ...
(i) The late transition metals, such as Rh, Ir and Pt, were reported to be selective for a competitive H2evolution reaction (HER). This is due to strong binding strengths of both CO* and H*, locating them on H2selective region (purple)20,21,22. Note that Pd is the exception of t...

In addition, no liquid product (i.e., CH3OH, HCOOH, and other alcohols) can be detected by 1H-NMR spectroscopy (Figure S3, catalyzed by m-Ni3Mn-LDH). A series of controlled photocatalytic experiments in Ar or N2 (Table S2) and the isotopic 13CO2 experiment (Figure 2C) demonstrated ...
the transformed lignin was isolated and characterized using NMR and GPC-MALS spectrometry. In these experiments, sLac was used as a positive control as it had previously been shown to transform lignin [7]. HSQC NMR spectra from laccase-treated lignin samples differed significantly from those of th...
1H NMR 1H NMR spectra were recorded using the AVANCE-III 600 NMR spectrometer (600 MHz, Bruker BioSpin, Switzerland). 6CF-Glc was dissolved in CD3OD. Data were processed using MestRENova (v.12.0.2, MestRElab Research, Spain). Liquid chromatography–mass spectrometry (LC-MS) ...
