| Abstract |
Carbon based nanomaterials have attracted much attentions due to their special physicochemical properties and diversiform shapes. Graphene quantum dots (GQDs) are defined as graphene sheets with few to ten layers and lateral dimensions < 100 nm. Zero-dimensional (0D) GQDs exhibit outstanding optical activity, robust chemical inertness due to their quantum confinement and edge effects. In this regard, modification of GQDs has been emerged as efficient approach for achieving superior nanosensors for selective detection of chemical and biological molecules. In this study, we report a simple method to prepare surface-functionalized GQDs by organic sulfur compounds, which exhibited enhanced electrocatalytic and photocatalytic performances. The relationships between the photocatalyst structure and the photocatalytic activities are discussed in detail. |
