Two copper phyllosilicates were prepared via co-precipitation accompanied by hydrothermal treatment at pH constant. The obtained materials were physically characterized by XRD, H2-TPR, TEM, BET and XPS techniques. The results indicated that Cu(II) ions were successfully intercalated into the phyllosilicate framework at a low Cu/Si molar ratio.

Worldwide petroleum reserves are decreasing rapidly; therefore, looking for sustainable and renewable energy is currently one of the targets of scientists. Biodiesel which can satisfy these requirements is synthesized by the transesterification of plant/animal oil with alcohols, typically methanol, catalyzed by acid or base.

Phosphatidylethanols (PEths) are specific, direct alcohol biomarkers with a substantially longer half-life than ethanol, and can be used to distinguish between heavy- and social drinking. More than forty PEth homologues have been detected in blood from heavy drinkers, and PEth 16:0/18:1 is the predominant one.

A complete liquid phase technology and a function regulator were applied to prepare CuZnAl catalysts for higher alcohol synthesis. Characterizations showed that the introduction of the function regulator can change the reduction ability of copper oxides and the surface basicity of catalysts. Activity tests indicated that the selectivity of higher alcohol is high when considerable medium-strong basicity and the synergistic effects of copper ion and metal copper exist on the catalytic surface.
