摘要：
Cu active nanoparticles (Cu ANPs) were synthesized in weakly acidic solution to preserve their catalytic activity. SiO2 capsules were designed to insulate Cu ANPs from oxidation. The weak interaction between SiO2 capsules and Cu ANPs ensured that the designed nanoparticles had good anti-oxidation property and potentially high activity. The increased anti-oxidation property with thicker SiO2 capsules (Cus3 >Cus2 >Cus1) and the order of reactivity to oxygen (Cus1 = Cus2 >Cus3) showed that Cu ANPs with SiO2 capsules (Cus2) of appropriate thickness would be the best for application. By us...
