Controllable integration of ultrasmall noble metal nanoparticles into mesoporous silica matrixes by a self-assembly method

Noble metal nanoparticles smaller than 2 nm were immobilized inside the channels of mesoporous silica via a self-assembly method using cetyltrimethylammonium chloride as a structural directing agent. This general approach can be used for integration of various precious metals into mesoporous silica matrixes of approximate to 30 nm to achieve better matter utilisation and higher catalytic activity.
