In summary, CNDs with tunable reducibility and emission have been synthesized with one-pot hydrothermal method. The red shift of emission was ascribed to the expansion of graphited core (sp2 domain) from b-CNDs to g-CNDs. And the discrepancy of reducibility was related to the tailoring of reductive surface groups. The abundant reductive groups on the surfaces endow the b-CNDs appealing reducibility, whereas the g-CNDs with few surface functional groups are deficient in reducibility. HAuCl4 as a

Controlled-synthesis of carbon nanodots (CNDs) with tunable properties has always been challenging. Here, novel CNDs (blue-emitting CNDs (b-CNDs) and green-emitting CNDs (g-CNDs)) with tunable redox abilities and emission are synthesized via one-pot hydrothermal method. The redox ability of CNDs is regulated by surface state tailoring. The abundant reductive groups on the surfaces endow the b-CNDs appealing reducibility, whereas g-CNDs with fewer surface functional groups are deficient in reducibility. Using HAuCl4 indicator, the distinct reduc...
