Sustainable chemistry research prioritizes reducing atmospheric carbon dioxide, and one logical solution is to develop adsorbents suitable for carbon capture and utilization. In this work, a new family of three-dimensional (3D) flower-like Mn-promoted MgO was synthesized by the coprecipitation method and used as an adsorbent for CO capture and a catalyst for CO utilization. The scanning electron microscopy (SEM) analysis of the samples shows a 3D architecture composed of thin nanosheets.

Treatment of PS-Hfsal-dmen with [V(IV)O(acac)(2)] in the presence of MeOH gave the oxidovanadium(IV) complex PS-[V(IV)O(fsal-dmen)(MeO)] (1). On aerial oxidation in methanol, complex 1 was oxidized to PS-[V(V)O(2)(fsal-dmen)] (2).

Treatment of [V(IV)O(acac)(2)] with PS-Hfsal-aepy in dimethylformamide (DMF) gave the oxidovanadium(IV) complex PS-[V(IV)O(fsal-aepy)(acac)] 1, which on oxidation yielded the dioxidovanadium(V) PS-[V(V)O(2)(fsal-aepy)] 2 complex. The corresponding neat complexes, [V(IV)O(sal-aepy)(acac)] 3 and [V(V)O(2)(sal-aepy)] 4 have also been prepared.

Upon treatment with [VO(acac)(2)] in DMF, the polystyrene-bound ligand (abbreviated as PS-Hsal-his, II) gave the stable polystyrene-bound oxidovanadium(iv) complex PS-[V(IV)O(sal-his)(acac)] , which upon oxidation yielded the dioxidovanadium(v) PS-[V(V)O(2)(sal-his)] complex. The corresponding non polymer-bound complexes [V(IV)O(sal-his)(acac)] and [V(V)O(2)(sal-his)] have also been obtained.
