Mesoporous nanomaterials not only possess strong ability to adsorb and interact with guest species both on their outer and inner surfaces, but also exhibit nanoscale effects in their channels and on the walls of their pores. This opens up intriguing possibilities for the design of highly activity catalysts by means of mesoporous materials. Here we present a facile method for the in-situ incorporation...
We have developed a facile and effective method to prepare chlorine and phosphorus-functionalized carbon dots (CDs) and investigated what the roles of these heteroatoms are played in carbon dot properties. Our researches suggested that Cl and P elements incorporated in superficial carbon atoms could tailor charge distribution on the surface of CDs, facilitating more effective photogenerated charge...
Fluorescent carbon dots (CDs) with oxygen-containing functional groups were prepared by a hydrothermal method. Three kinds of typical oxygen functional groups, i.e. hydroxyl, carbonyl, and carboxylic acid groups, were selectively deactivated to independently assess their photocatalytic activities on the surface of CDs. The presented results indicate that the carbonyl group on CDs is their photocatalytic...
A novel method was developed to synthesize graphite oxide/TiO 2 composites as a highly efficient photocatalyst by in situ depositing TiO 2 nanoparticles on graphene oxide nano-sheets by a liquid phase deposition, followed by a calcination treatment at 200°C. The two-dimensional porous graphene oxide/TiO 2 composites had specific surface area of 80m 2 g −1 being...
