Abstract
- The formation of PdZn bimetallic alloys on ZnO, TiO<subscript>2</subscript> and Al<subscript>2</subscript>O<subscript>3</subscript> supports was investigated, together with the effect of alloy formation on the CO<subscript>2</subscript> hydrogenation reaction. The chemical vapour impregnation (CVI) method produced PdZn nanoparticles with diameters of 3–6 nm. X-ray photoelectron spectroscopy and X-ray diffraction revealed the changes in the structure of the PdZn alloy that help stabilise formate intermediates during methanol synthesis. PdZn supported on TiO<subscript>2</subscript> exhibits high methanol productivity of 1730 mmol kg<subscript>cat</subscript><superscript>−1</superscript> h<superscript>−1</superscript> that is associated with the high dispersion of the supported PdZn alloy.
