Abstract
Although sub-nano quantum dots (QDs) are now becoming the most fascinating materials in nanotechnology, the accurate syntheses of QDs are generally difficult. Facile templating methods utilizing porous materials have a limitation due to an existence of the uncontrollable pore diameter range between 0.7 and 1.1 nm. In this study, the missing link has been entirely bridged with successful production of supermicroporous silicas (SMPSs) by using a solvent-free method. The finely tuned sub-nano pores of SMPSs act as an excellent template for the preparation of sub-nano QDs of transition metal oxides.
