Embodiment 1

[0041] Preparation of Fe-HTCPP-La:

[0042] Ligand H 6 TCPP (0.012mmol), FeCl 2 4H 2O (0.01mmol) and La 2 (C 2 o 4 ) 3 10H 2 O (0.012mmol) was added to a hard glass tube, and then DMF (2mL) and 0.8N hydrochloric acid aqueous solution (3mL) were added. h rate to cool to room temperature. After the tube was opened, the crystals were collected by filtration, washed three times with 20 mL of DMF and three times with 20 mL of methanol, and dried to obtain a metal organic framework material, which was designated as Fe-HTCPP-La.

Embodiment 2

[0044] Preparation of Co-HTCPP-La:

[0045] Ligand H 6 TCPP (0.012mmol), CoCl 2 4H 2 O (0.01mmol) and La 2 (C 2 o 4 ) 3 10H 2 O (0.01mmol) was added to a hard glass tube, then DMF (2mL) and 0.8N hydrochloric acid aqueous solution (3mL) were added, and after packaging, the mixture was heated in an oven at 150°C for 50 hours, and then heated at 5°C / h rate to cool to room temperature. After the tube was opened, the crystals were collected by filtration, washed three times with 20 mL of DMF and three times with 20 mL of methanol, and dried to obtain a metal organic framework material, which was designated as Co-HTCPP-La.

Embodiment 3

[0047] Preparation of Ni-HTCPP-La:

[0048] Ligand H 6 TCPP (0.012mmol), NiCl 2 ·6H 2 O (0.01mmol) and La 2 (C 2 o 4 ) 3 10H 2 O (0.015mmol) was added to a hard glass tube, then DMF (2mL) and 0.8N hydrochloric acid aqueous solution (2mL) were added, and after packaging, the mixture was heated in an oven at 150°C for 50 hours, and then heated at 5°C / h rate to cool to room temperature. After the tube was opened, the crystals were collected by filtration, washed three times with 20 mL of DMF and three times with 20 mL of methanol, and dried to obtain a metal organic framework material, which was designated as Ni-HTCPP-La.

Abstract

The invention provides a rare earth metal porphyrin framework material and a preparation method and application thereof, the general formula of the rare earth metal porphyrin framework material is M-HTCPP-Ln, wherein M is metal iron or metal cobalt or metal nickel or metal manganese or metal zinc, and Ln is metal lanthanum or metal europium or metal gadolinium or metal cerium. The rare earth metal porphyrin framework material provided by the invention has excellent catalytic performance, generates a large amount of singlet oxygen under a certain illumination condition, quickly and selectively oxidizes a thiomustard simulant into a green and environment-friendly sulfoxide compound, has very high selectivity and very good thermal stability, can be synthesized in a batch amplification manner, and has good repeatability. Meanwhile, the synthesis process is simple in flow and high in operability, and has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of photocatalysis, and in particular relates to a rare earth metal porphyrin framework material and a preparation method and an application method thereof. Background technique [0002] Mustard oil bis(2-chloroethyl) sulfide (expressed as HD) was widely used as a chemical weapon in the late World War I. HD was used as a war poison. necrosis. Selective oxidation of HD to sulfoxides is a mild and environmentally friendly approach. Among various oxidizing agents, singlet oxygen ( 1 o 2 ) is particularly prominent and is a mild oxidizing agent, therefore, the development can efficiently produce 1 o 2 As well as novel photocatalysts that rapidly degrade HD are an urgent and challenging work. [0003] Metal-Organic Frameworks (MOFs) are coordination framework materials composed of metal ions and organic ligands self-assembled. Materials with such structures may not only contain the characteristics of metals ...
