Two-dimensional (2D) layered nanomaterial heterostructures, arising from the combination of 2D materials with other low-dimensional species, feature a large surface area to volume ratio, which provides a high density of active sites for catalytic applications and for (photo)electrocatalysis (PEC). Meanwhile, their electronic band structure and high electrical conductivity enable efficient charge transfer (CT) between the active material and the substrate, which is essential for catalytic activity. In recent years, researchers have demonstrated the potential of a range of 2D material interfaces, such as graphene, graphitic carbon nitride (g-C3N4), metal chalcogenides (MCs), and MXenes, for (photo)electrocatalytic applications. For instance, MCs such as MoS2 and WS2 have shown excellent catalytic activity for hydrogen evolution, while graphene and MXenes have been used for the reduction of carbon dioxide to higher value chemicals. However, despite their great potential, there are still major challenges that need to be addressed to fully realize the potential of 2D materials for PEC. For example, their stability under harsh reaction conditions, as well as their scalability for large-scale production are important factors to be considered. Generating heterojunctions (HJs) by combining 2D layered structures with other nanomaterials is a promising method to improve the photoelectrocatalytic properties of the former. In this review, we inspect thoroughly the recent literature, to demonstrate the significant potential that arises from utilizing 2D layered heterostructures in PEC processes across a broad spectrum of applications, from energy conversion and storage to environmental remediation. With the ongoing research and development, it is likely that the potential of these materials will be fully expressed in the near future.

Zinc−cobalt double-metal sulfides (ZCSs) with kinds of structures as electrode materials play an essential role in supercapacitors (SCs). However, their poor electronic transfer efficiency and irreversible structural damage greatly affect their practical applications. The idea of high structural stability and bimetal synergy (Zn-Co) is introduced to prepare high-performance electrodes and construct hybrid supercapacitors. A unique graphite sheet-supported ZCS nanoparticle is grown on porous Ni foam (GZCS/NF) by a facile hydrothermal and ion-exchange reaction. The unique nanosheet structure with a nanosheet of about 80 nm exhibits a specific capacity of 1293.5 C g −1 at 1 A g −1 , a relatively low charge-transfer resistance of 0.16 Ω, and superior cycling stability, which can be attributed to the excellent pseudocapacitive capacity of ZCS nanoparticles and the good chemical stability of the graphite sheet. A hybrid supercapacitor in KOH solution is assembled with GZCS/NF as the cathode and AC as the anode. The assembled GZCS/NF//AC HSC delivers a wide working voltage of 1.7 V and a specific capacity of 196.4 C g −1 at 1 A g −1 . Its ability to light up eight red LEDs for about 7 min proves its good prospects in energy storage devices.

The proliferation of rechargeable lithium‐ion batteries (LIBs) over the past decade has led to a significant increase in the number of electric vehicles (EVs) powered by these batteries reaching the end of their lifespan. With retired EVs becoming more prevalent, recycling and reusing their components, particularly graphite, has become imperative as the world transitions toward electric mobility. Graphite constitutes ≈20% of LIBs by weight, making it a valuable resource to be conserved. This review presents an in‐depth analysis of the current global graphite mining landscape and explores potential opportunities for the “second life” of graphitefrom depleted LIBs. Various recycling and reactivation technologies in both industry and academia are discussed, along with potential applications for recycled graphite forming a vital aspect of the waste management hierarchy. Furthermore, this review addresses the future challenges faced by the recycling industry in dealing with expired LIBs, encompassing environmental, economic, legal, and regulatory considerations. In conclusion, this review provides a comprehensive overview of the developments in recycling and reusing graphite from retired LIBs, offering valuable insights for forthcoming large‐scale recycling efforts.
