Carbon dots (CDs), an emerging category of carbon nanomaterials, have bright destiny in a vast diversity of engineering areas due to their great variety in design, arrangement, and characteristics. Their possible implementations have recently traversed from electrochemical energy storage (EES), fluorescent probing, and catalysis, particularly as materials into the critical elements of the electrochemical system. Herein, the current investigation based upon the preface of CDs in batteries, supercapacitors, hydrogen/oxygen evolution reaction, oxygen reduction reaction, electromagnetic interference shielding, and solar‐assisted energy generation used as electrode materials integrated with an active substance as an auxiliary mechanism is shown. Different aspects conferred upon selected illustrations outline the electrochemical activity, and eventually, current issues and future viewpoints are recollected toward the following optimization method of electrode substances. This review article is anticipated to demand broad attention within active CD materials and encourage the growth of high‐performance EES systems.

The Transformation of 0-D Carbon Dots into 1-, 2- and 3-D Carbon Allotropes: A Minireview

Carbon dots (CDs) represent a relatively new type of carbon allotrope with a 0-D structure and with nanoparticle sizes < 10 nm. A large number of research articles have been published on the synthesis, characteristics, mechanisms and applications of this carbon allotrope. Many of these articles have also shown that CDs can be synthesized from “bottom-up” and “top-down” methods. The “top-down” methods are dominated by the breaking down of large carbon structures such as fullerene, graphene, carbon black and carbon nanotubes into the CDs. What is less known is that CDs also have the potential to be used as carbon substrates for the synthesis of larger carbon structures such as 1-D carbon nanotubes, 2-D or 3-D graphene-based nanosheets and 3-D porous carbon frameworks. Herein, we present a review of the synthesis strategies used to convert the 0-D carbons into these higher-dimensional carbons. The methods involve the use of catalysts or thermal procedures to generate the larger structures. The surface functional groups on the CDs, typically containing nitrogen and oxygen, appear to be important in the process of creating the larger carbon structures that typically are formed via the generation of covalent bonds. The CD building blocks can also ‘aggregate’ to form so called supra-CDs. The mechanism for the formation of the structures made from CDs, the physical properties of the CDs and their applications (for example in energy devices and as reagents for use in medicinal fields) will also be discussed. We hope that this review will serve to provide valuable insights into this area of CD research and a novel viewpoint on the exploration of CDs.

Restricted rate capability is the key bottleneck for the large‐scale energy storage of battery‐type supercapacitor cathode due to its sluggish reaction kinetics. Herein, Ni(Co)Se2@Co(Ni)Se2 semicoherent heterojunctions with rich Se vacancies (Vr‐Ni(Co)Se2@Co(Ni)Se2) as cathode are first constructed. Such a vacancy and heterointerface manipulation can not only essentially regulate the electronic structure and enhance ions adsorption capability, but also rationalize the chemical affinities of OH– ions in diffusion pathway revealed by systematic characterization analysis and first‐principle calculations. The as‐prepared cathode delivers large specific capacity of 264.5 mAh g–1 at 1 A g–1 and excellent cycle stability. Surprisingly, it presents ultrahigh rate with the retention of 159.7 mAh g–1 even at 250 A g–1. Moreover, the single phase transition mechanism of the cathode is elucidated systematically using series of ex situ techniques. In addition, contributed by the unique cathode and the self‐synthesized N/S co‐doped corncob‐derived porous carbon (N/S‐BPC, 316.1 F g–1 at 1 A g–1) anode, a high‐performance hybrid supercapacitor (HSC) is developed, which shows the energy density of 68.1 Wh kg–1 at 0.75 kW kg–1 and a superior cycle performance. The findings highlight a coordination strategy for the rational design of ultrahigh‐rate battery‐type HSC cathode, greatly pushing their commercial application processes.
