Abstract
Colloidal solutions of ZnO-Cu nanoparticles can be used as catalysts for the reduction of carbon dioxide with hydrogen. The use of phosphinate ligands for the synthesis of the nanoparticles from organometallic precursors improves the reductive stability and catalytic activity of the system.

Colloidal solutions of ZnO–Cu nanoparticles can be used as catalysts for the reduction of carbon dioxide with hydrogen
Copper nanoparticles have been primarily synthesised by the reduction of inorganic copper(II) salts (CuSO4), with hydrazine hydrate, in the presence of an excess of a neutral coordinating surfactant such as an alkyl-amine.[10]
Copper nanoparticles, with stearate ligands were formed by the reaction of Cu(stearate)[2], in squalane solution at 60 1C, with two equivalents of hydrazine, dissolved in THF
Summary
Colloidal solutions of ZnO–Cu nanoparticles can be used as catalysts for the reduction of carbon dioxide with hydrogen. The use of phosphinate ligands for the synthesis of the nanoparticles from organometallic precursors improves the reductive stability and catalytic activity of the system.
