Synthesis of new types of heterostructures is an important topic in modern materials chemistry and functional interfaces. The aim of the study was to explore new kind of triple composite material derived from microporous hybrid halide, [Co(phen)3]2[Ag13Br17]·2DMSO·3H2O (where phen denotes o-phenanthroline and DMSO denotes dimethyl sulfoxide), Mo2Ti2C3@S MXene and a new metal-organic framework (MOF) of a bilayer structure, [Co(H2iso)(pim)], derived from isophthalic hydrazide (H2iso), pimelic acid (H2pim) and cobalt(II) ions. The hybrid halide was obtained using a procedure that had already been published.[1] The MXene was obtained in hydrogen fluoride delamination of the corresponding MAX phase (Mo2Ti2AlC3) and decorated MXene with sulfur using the vapour transport method (500 oC, 25h). The MOF was obtained by aqueous self-assembly in the presence of potassium carbonate (K2CO3) at room temperature. The characterization of the triple composite and its isolated components (as well as pairs, such as MXene-MOF and hybrid halide-MOF) is performed, including morphology and properties.

The research of P. Z. leading to these results was supported by the Johannes Amos Comenius Programme, European Structural and Investment Funds, project ‘CHEMFELLS V’ (No. CZ.02.01.01/00/22_010/0003004).
