Triple-shell hollow spheres of crystalline copper–nickel ferrite have been synthesized in a simple one-pot procedure using carbon spheres as templates via a hydrothermal approach. Ferric nitrate, copper nitrate, and nickel nitrate were dissolved in water together with glucose, and the mixture was heated to 180 °C in an autoclave. Finally, the carbon core was removed by calcination at 550 °C. The triple-shell hollow spheres of CuNiFe2O4 were characterized by XRD, TEM, FE-SEM, and EDS. High catalytic activity for the Suzuki reaction was obtained for this new triple-shell hollow sphere of CuNiFe2O4. This also reveals obvious advantages such as the recyclability of the catalyst, simple experimental operation, and excellent yields.

轻巧的水热合成新型中空三层CuNiFe 2 O 4纳米球,在Suzuki-Miyaura偶联反应中具有强大的催化性能
结晶铜-镍铁氧体的三层空心球是通过水热法以碳球为模板,通过简单的一锅法合成的。将硝酸铁,硝酸铜和硝酸镍与葡萄糖一起溶解在水中,并将混合物在高压釜中加热至180℃。最后,通过在550℃下煅烧除去碳核。用XRD,TEM,FE-SEM和EDS对CuNiFe 2 O 4的三层空心球进行了表征。这种新型的三层空心CuNiFe 2 O 4球获得了对Suzuki反应的高催化活性。这也显示出明显的优点,例如催化剂的可回收性,简单的实验操作和优异的产率。
