TiO₂ nanosheets and metal-organic framework (NH₂-UiO-66) were effectively coupled via an in‐situ growth strategy to form bifunctional materials for the combined capture and photocatalytic reduction of CO₂ under UV–vis light irradiation. This was done to take advantage of the high CO₂ adsorption capacity of the MOF and the photocatalytic properties of pre-formed TiO₂ nanosheets in a single material. The prepared materials were thoroughly characterized using a variety of techniques. They were subsequently tested for CO₂ adsorption and CO₂ photocatalytic reduction using a heterogeneous gas/solid set-up to imitate both CO₂ capture and fixation in a single process. The adopted synthesis process allowed the development of a tight interaction between TiO₂ and NH₂-UiO-66 forming a heterojunction, while maintaining both the high CO₂ uptake and porosity of NH₂-UiO-66. The nanocomposites were proven …
