Activated carbon-supported CuO catalysts were prepared by an ammonia evaporation method and applied to catalyze the selective oxidation of glycerol to lactic acid. The effects of CuO loadings on the ...

In this study, tannic acid (TA) was applied as a stabilizing agent for synthesizing bimetallic copper–gold (CuAu) nanoparticles. Cu(NO3)2 and NaAuCl4 were used as the sources of copper and gold ions, ...

A new study could mark a shift in our dependence on rare earth metals to simple iron oxide for all our future devices and gadgets.
