Abstract: In order to enhance the stability and scalability of porous nano metal organic skeleton composites, reduce synthesis costs and environmental impacts, and promote the development of multiple fields such as environmental pollution control and material science. This article mainly focuses on the preparation and photocatalytic performance of novel porous nano metal organic skeleton composite material. Reagents and instruments were selected, and the metal organic framework substrate and TiO₂ nanoparticles were synthesised. The TiO₂ nanoparticles were embedded into the pores of the metal-organic framework to achieve material preparation. The test results showed that TiO₂ was uniformly dispersed on the surface of the composite material, exhibiting both the characteristic peaks of the metal-organic framework material and TiO₂, with the highest excitation emission peak at 450 nm. The prepared composite material demonstrated strong adsorption capacity for MB, high photocatalytic efficiency, excellent photocatalytic degradation of RhB, a large amount of hydrogen production through water photolysis.

Keywords: novel porous nano; metal organic framework; composite material; material preparation; photocatalytic performance.
