The MOF-74 materials belong to a category of high-entropy metal-organic frameworks (MOFs) that are porous, hollow and composed of divalent metal ions including Mn, Fe, Mg, Co, Ni, Cu and Zn.As a new nanomaterial, MOF-74 has been extensively investigated in the fields of environment, biomedicine and so on. Phosphorus is an indispensable element for the growth and development of plants, yet many agricultural soils in the world exhibit low phosphorus utilization and may suffer from deficiency in this nutrient. In this paper, MOF-74(Mg) adsorbed inorganic phosphorous were synthesized at room temperature and characterized by X-ray diffractometer (XRD) and Fourier infrared spectroscopy (FTIR). Field emission scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) were conducted on pea plant leaves sprayed with MOF-74(Mg) adsorbed inorganic phosphorus, the results showed that MOF-74(Mg) adsorbed inorganic phosphorous could be used as phosphorus sustained-release fertilizer for leaves.
