Herein, we report the application of four amino-tris(phenolate)-based metal complexes incorporating Ti(IV) or Zr(IV) centres (2a-3b) as homogeneous catalysts for conversion CO2 and epoxides into cyclic carbonates. The were synthesised, characterised then evaluated in combination with tetrabutylammonium iodide, bromide chloride binary catalytic systems reaction 1,2-epoxyhexane epoxide substrate ...

Considering the increasing demand for titania nanoparticles with controlled quality for various applications, the present work reports the up-scalable synthesis of size-controlled titanium dioxide nanocrystals with a simple and convenient thermal treatment route. Titanium dioxide nanocrystals with tetragonal structure were synthesized directly from an aqueous solution containing titanium (IV) i...
