Preparation and Performance of Fluorine-Functionalized Ni-MOF-74 Adsorption Columns
Gas tracer technology plays a crucial role in enhancing oil recovery during oil and gas field development. However, the limited storage capacity and detection efficiency of current gas tracers hinder their broader application. In this study, Ni-MOF-74 was successfully synthesized through a solvothermal method and subsequently modified by grafting perfluoroalkyl chains. The results demonstrated that the crystal structure and morphology of the material remained stable following fluorination, while its thermal stability was significantly improved. Notably, the specific surface area decreased with the increasing length of the grafted perfluoroalkyl chains, accompanied by a reduction in surface free energy. Additionally, the number of Lewis acidic sites increased, while the number of Lewis basic sites decreased. Adsorption performance tests revealed that the modified Ni-MOF-74 exhibited high adsorption capacities for difluorochloromethane (R22) and tetrafluoroethane (R134a), with values of 2.623 mmol·g−1 and 2.385 mmol·g−1, respectively. These capacities were significantly higher than those of conventional activated carbon adsorption tubes. This study offers a novel approach to efficient gas tracer storage/detection and provides theoretical insights into the potential application of metal–organic frameworks (MOFs) in oil and gas field development.
期刊介绍：
All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
