The Behavior of Carbon Dots in Catalytic Reactions

Since their discovery in 2004, carbon dots (CDs), with particle sizes < 10 nm, have found use various applications, mainly based on the material’s fluorescent properties. However, other potential uses of CDs remain relatively unexplored when compared to carbon-based nanomaterials. In particular, as catalysts and supports for catalytic reactions, is still its infancy. Many studies indicated advantages using catalysis, but there are difficulties associated stability, separation, aggregation due small size. This size does however allow studying interaction catalyst particles dimensional supports, including inverse support interaction. recent that not stable under high temperature conditions (especially >250 °C; without a catalyst) suggesting may agglomerate transform some reaction conditions. The agglomeration metal CD/metal catalyst, especially because transformation at temperature, always considered catalysts, post-reaction analysis undertaken. Further, it appears modest thermal conditions, can react ions change morphology, relates reducibility. review has thus been undertaken indicate advantages, well limitations, studies. techniques used evaluate these issues given, examples from literature highlight catalysis described.
