They are sometimes identified as zero-dimensional (0D) nanoparticles. These particles have gained much attention in water splitting into hydrogen and oxygen through photocatalytic conversion. CQDs act as semiconductor few nm sizes, due to very small size; their optical and electronic properties differ from larger particles. CQDs particle has high stability, mild toxicity besides conductivity. These particles are environmentally friendly due to low toxicity and also have excellent luminescence. Therefore they can be utilized as a potential source for the splitting of water photocatalytically. The parting of water into H2 and O2 will enable us to produce or collect hydrogen to be used as a future fuel. The review summarizes the efforts made by various researchers in the field of utilizing carbon quantum dabs for water splitting which may be further followed by future researchers for commercial-scale hydrogen production. Thus, the study concludes the methods for the production of CQDs and their utilization under sunlight by catalytically hydrogen gas production from water.

碳量子点光催化制氢综述:未来燃料

它们有时被识别为零维 (0D) 纳米粒子。这些颗粒在通过光催化转化将水分解为氢和氧方面受到了广泛关注。由于尺寸非常小,CQD 可作为几纳米尺寸的半导体;它们的光学和电子特性不同于较大的颗粒。CQDs粒子除了具有导电性外,还具有高稳定性、温和的毒性。这些颗粒由于毒性低而对环境友好,并且还具有优异的发光性。因此,它们可以用作光催化分解水的潜在来源。水分离成H 2和O 2将使我们能够生产或收集用作未来燃料的氢气。该综述总结了各种研究人员在利用碳量子 dab 进行水分解方面所做的努力,未来的研究人员可能会进一步跟进以进行商业规模的制氢。因此,该研究总结了通过从水中催化产生氢气来生产 CQD 的方法及其在阳光下的利用。
