In situ embedding of ultra-fine nickel oxide nanoparticles in HMS with enhanced catalytic activities of styrene epoxidation

Firstly, in this method, nickel ions would be anchored on the surface of micelles by coordination to form metallomicelles (S0M+), and then the metallomicelles would be matched with electronegative silicate oligomers (I−) through counterion-mediated interaction. Finally, after removing the template by calcining, highly-dispersed and ultra-fine NiO NPs could be well-distributed in the channel of mesoporous silica.306
