Recent progress in the g-C3N4 quantum dots: synthesis, properties and applications in photocatalytic degradation of organic pollutants
Graphitic-carbon nitride quantum dots (g-C3N4QDs), as a rising star in the carbon nitride family, show great potentials in many fields involving bioimaging, fuel cells, and photo(electro)catalysis, endowed by their fascinating optical and electronic properties. Especially, the efficient light capture, tunable photoluminescence and extraordinary up-conversion photoluminescence properties of g-C3N4QDs may offer promising potential for full utilization of the solar spectrum, thus promoting their applications in photocatalytic reactions. Numerous reviews on g-C3N4 have been presented, while most of them have concentrated on g-C3N4 in 3-dimensional (3D) or 2D structures and few focuses on g-C3N4QDs. Thereby, this review aims to summarize the recent advances of g-C3N4QDs in their synthesis, optical and electronic properties and photocatalytic applications for degrading organic pollutants. Moreover, crucial issues in g-C3N4QDs future application in these flourishing research areas are discussed, with the perspective towards the final realization of efficient and long-term stable g-C3N4QDs-based photocatalysts.
