Matrix Assisted and/or Laser Desorption Ionization Quadrupole Ion Trap Time-of-Flight Mass Spectrometry of WO{sub 3} Clusters Formation in Gas Phase. Nanodiamonds, Fullerene, and Graphene Oxide Matrices
- Masaryk University, Department of Chemistry, Faculty of Science (Czech Republic)
The formation of W{sub x}O{sub y}{sup +●/-●} clusters in the gas phase was studied by laser desorption ionization (LDI) and matrix assisted laser desorption ionization (MALDI) of solid WO{sub 3}. LDI produced (WO{sub 3}){sub n}{sup +●/-●} (n = 1-7) clusters. In MALDI, when using nano-diamonds (NDs), graphene oxide (GO), or fullerene (C{sub 60}) matrices, higher mass clusters were generated. In addition to (WO{sub 3}){sub n}{sup -●} clusters, oxygen-rich or -deficient species were found in both LDI and MALDI (with the total number of clusters exceeding one hundred ≈ 137). This is the first time that such matrices have been used for the generation of(WO{sub 3}){sub n}{sup +●/-●} clusters in the gas phase, while new high mass clusters (WO{sub 3}){sub n}{sup -●} (n = 12-19) were also detected. .
