“…Nguyen and Shim designed and synthesized an N‐doped carbon quantum dots/multiwalled carbon nanotubes (CDs/CNTs) hybrid by a facile and scalable synthesis method. [ 275 ] The obtained CDs/CNT exhibited excellent ORR activity ( E 1/2 = 0.834 V vs RHE) with favorable kinetics, as well as high durability ascribed to the synergistic effect of CDs and CNTs.

Nitrogen‐doped carbons are among the fastest‐growing class of materials used for oxygen electrocatalysis, namely, the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER), thanks to their low cost, environmental friendliness, excellent electrical conductivity, and scalable synthesis. The perspective of replacing precious metal‐based electrocatalysts with nitrogen‐doped carbon is highly desirable for reducing costs in energy conversion and storage systems. In this review, the role of nitrogen and N‐induced structural defects on the enhanced performance of N‐doped carbon electrocatalysts toward the OER and the ORR as well as their applications for energy conversion and storage technologies is summarized. The synthesis of N‐doped carbon electrocatalysts and the characterization of their nitrogen functional groups and active sites for the conversion of oxygen are also reviewed. The electrocatalytic performance of the main types of N‐doped carbon materials for OER/ORR electrocatalysis are then discussed. Finally, major challenges and future opportunities of N‐doped carbons as advanced oxygen electrocatalysts are highlighted.

“…Defective oxygen-containing moieties were randomly distributed in the basal plane and edge sites. 60 Wang et al effectively combined the graphene oxide quantum dots (GOQDs) into graphene/carbon nanotube (CNT) hybrid structures using GOQDs-dispersed solution. 69 GOQDs with abundant oxygen containing functional groups and unsaturated bonds provided nitrogen and sulfur doping sites, which increased the doping level of electrocatalysts.…”

“…CDs have positively inferior oxygen-possessed moieties dispersed unsystematically on the basal plane and border areas. [104] Current research indicates that N-doped CNMs appear to be an exemplary process for promoting ORR. For example, Qu et al [105] prepared N-doped GQDs (N-GQDs) through CV cycles.…”

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.

Abstract: The ORR measurements showed that the CD(ED)/CNT catalyst was superior to CD(EG)/CNT and CD(EA)/CNT. They even surpassed the activity of commercial Pt/C in terms of durability, Tafel slope, and MeOH tolerance.
