چکیده
In alloyed nanoparticles, synergistic electronic and/or geometric effects may enhance the catalytic properties compared to their monometallic counterparts. Herein, we address synthesis of bimetallic Au/Cu nanoparticles with different compositions by wet chemical reduction in ionic liquids. The were successively supported on carbon. liquid could be recycled after synthesis. Annealing carbon-supported NPs at 400 °C led ordered intermetallic L10 AuCu phase. nanoparticle-derived catalysts characterized X-ray diffraction analysis, transmission electron microscopy, photoelectron spectroscopy and optical emission inductively coupled plasma. Oxidation biomass-derived furans is a prominent process for biomass transformation into value-added chemicals. oxidation 5-hydroxymethyl-2-furfural (HMF) 2,5-furandicarboxylic acid (FDCA) was chosen as model reaction evaluate effect Cu addition structure performance. Particularly an ratio 3 : 1 showed very high conversion FDCA.

An ionic liquid (IL) is a salt in the liquid state. In some contexts, the term has been restricted to salts whose melting point is below some arbitrary temperature, such as 100 °C. While ordinary liquids such as water and gasoline are predominantly made of electrically neutral molecules, ionic liquids are largely made of ions and short-lived ion pairs. These substances are variously called liqu...
