“…243 Chang et al synthesized the single atomically anchored iron-on graphene quantum dots by using hydrothermal and subsequent use the simple chemical method to prepare composite and the prepared material used as electrocatalyst for electrocatalytic OER. 244 The optimized 248 Extensive experiments show that NGQDs-limiting self-assembly of CoP molecules along the axial path, followed by the creation of Z-scheme CoP/NGQDs heterojunctions, is critical for effective photocatalytic oxygen evolution. These unagglomerated CoP nanowires are effectively interacting with the light and increase the stability of photoinduced charge in CoP/NGQDs than the CoP nanowire.…”

Carbon quantum dots (CQDs) are a class of carbon nanomaterials that have recently gained recognition as current entrants to traditional semiconductor quantum dots (QDs). CQDs have the desirable advantages of low toxicity, environmental friendliness, low cost, photostability, favorable charge transfer with enhanced electronic conductivity, and their comparable easy synthesis protocols. This article examines advancements in CQD research and development, with a focus on their synthesis, functionalization, and energy applications. Initially, various synthesis methods are discussed briefly with pros and cons. Herein, first top-down methods including arc discharge technique, laser ablation technique, plasma treatment, ultrasound synthesis technique, electrochemical technique, chemical exfoliation, and combustion were discussed briefly. The later section presents bottom-up (microwave synthesis, hydrothermal synthesis, thermal pyrolysis, and MOF template-assisted approach) and waste-derived CQDs synthesis methods. The next section is focused on the energy applications of CQDs including supercapacitors, lithium-ion batteries, photovoltaics, hydrogen (HER), and oxygen evolution reaction (OER). Finally, challenges and perspectives in this exciting and promising area are presented.

“…[97] Chang and colleagues established an original coordination adsorption approach for the synthesis of monodispersed Fe single atoms attached on nitrogen anchoring sites of nitrogen-doped graphene quantum dots (N-GQDs) to form Fe(NO) 2 -N-GQDs as compelling OER electrocatalysts. [84] First, the graphite powder was deeply exfoliated by PyBr 3 to obtain a colloidal suspension of graphene layers. Subsequently, N-GQDs were synthesized from graphene layers using a hydrothermal method.…”

The fundamental relationship between structure and properties, which is called “structure‐property”, plays a vital role in the rational designing of high‐performance catalysts for diverse electrocatalytic applications. Low‐dimensional (LD) nanomaterials, including 0D, 1D, 2D materials, combined with low‐nuclearity metal atoms, ranging from single atoms to subnanometer clusters, are currently emerging as rising star nanoarchitectures for heterogeneous catalysis due to their well‐defined active sites and unbeatable metal utilization efficiencies. In this work, a comprehensive experimental and theoretical review is provided on the recent development of single atom and atomic cluster‐decorated LD platforms towards some typical clean energy reactions, such as water‐splitting, nitrogen fixation, and carbon dioxide reduction reactions. The upmost attractive structural properties, advanced characterization techniques, and theoretical principles of these low‐nuclearity electrocatalysts as well as their applications in key electrochemical energy devices are also elegantly discussed.

Electrocatalytic reactions possess wide application prospects in solving the energy crisis. Recently, the emerging 0D carbon dots (CDs) have become potential candidate materials due to their low cost, high conductivity, easy modification, and simple synthesis. CDs-based composite materials showcase attractive electrocatalytic performances because of the abundant active sites and charge distribution on the material surface. Considering the complicated structure of CDs, it's important to identify the specific catalytic activity source and understand catalytic mechanisms with the aid of theoretical method. In this review, the latest advancements are presented on improving the electrocatalytic activity and stability of CDs-based composite materials from theoretical perspective. Meanwhile, the opportunity and challenges about developing high-performance CDs catalysts are also highlighted.
