Template-free biosynthesis of flowerlike CuO microstructures using Cinnamomum camphora leaf extract at room temperature

Plant‐Mediated Synthesis of Zinc Oxide Supported Nickel‐Palladium Alloy Catalyst for the Selective Hydrogenation of 1,3‐Butadiene

“…The ZnO and CuO supports used were prepared by a similar method to that used in our previous studies with minor adjustments . Typically, Zn(NO 3 ) 2 ⋅6 H 2 O (30 mL, 0.2 mol L −1 ) and Cu(NO 3 ) 2 ⋅3 H 2 O (30 mL, 0.1 mol L −1 ) solutions were added to C. camphora leaf extract (10 and 20 mL, respectively) in a 150 mL round‐bottomed flask and kept at RT to age for 1 h. The respective mixtures were dried in the oven at 80 °C for 10 h and then annealed at 450 °C 4 h. The obtained metal oxides were milled by using a pestle and mortar, then sieved through a 50 mm mesh, and stored for further use.…”
