The effect of oxidative debris (OD) on the fragmentation behavior and the laser desorption/ionization (LDI) process of graphene oxide (GO) derivatives was systematically investigated to explore the potential of LDI time-of-flight mass spectrometry (LDI-TOF-MS) as a characterization tool for their chemical structure and photochemical properties. Based on the results, we found that the fragmentation patterns and the LDI properties of the GO derivatives were highly affected by the OD adsorbed on their surface. Our findings suggest that LDI-TOF-MS can be a useful analytical tool for determining the chemical structure and photochemical properties of GO derivatives.

氧化碎片对氧化石墨烯衍生物的裂解和激光解吸/电离过程的影响

系统研究了氧化碎片(OD)对氧化石墨烯(GO)衍生物的碎片行为和激光解吸/电离(LDI)过程的影响,以探索LDI飞行时间质谱(LDI-TOF- MS)作为表征其化学结构和光化学性质的工具。根据结果​​,我们发现GO衍生物的碎片模式和LDI性质受到其表面吸附的OD的高度影响。我们的发现表明,LDI-TOF-MS可以作为确定GO衍生物的化学结构和光化学性质的有用分析工具。
