Counteracting reactive oxygen species (ROS, e.g., superoxide radical ion, H2O2 and hydroxyl radical) is an important task in fighting against oxidative stress-related illnesses and in improving product quality in industrial manufacturing processes. This review focuses on the recent advances on two-dimensional (2D) nanomaterials of antioxidant activity, which are designed for effective decomposition of ROS and thus, for reduction of oxidative stress. Some materials featured in this paper are of uni- or multi-lamellar structures modified with small molecular or enzymatic antioxidants. Others are enzyme-mimicking synthetic compounds (the so-called nanozymes) prepared without antioxidant additives. However, carbon-based materials will not be included, as they were extensively reviewed in the recent past from similar aspects. Given the landmark development around the 2D materials used in various bio-applications, sheet-like antioxidant compounds are of great interest in the scientific and technological communities. Therefore, the authors hope that this review on the recent progresses will be helpful especially for researchers working on novel developments to substantially reduce oxidative stress either in biological systems or industrial liquors.

“…Moreover, the electrical conductivity of 2D MOFs is significantly higher than bulk MOFs, due to the dramatically decreased electron transfer distance from the ultrathin nanosheets to the current collector of the electrodes [8]; and thus mitigates the MOFs' inherent challenging poor electrical conductivity. Further, if assembled in a suitable way, MOF nanosheets can form an appropriate structure with a combination of hierarchical pores.…”

“…Recently, we and some other groups have proposed a promising strategy of downsizing MOFs into twodimensional (2D) ultrathin nanosheets [6][7][8][9], which has opened up a new direction of using MOFs for various applications. With the witness of fast-growing research in this direction, this perspective will build on relevant works by examining the potential application of such materials, particularly as electrocatalysts.…”

In this short perspective we examine recent developments in the design, synthesis and use of metalorganic frameworks (MOFs) for electrocatalytic applications. We discuss the inherent challenges and limitations that continue to plague conventional MOFs and novel strategies for overcoming them. In particular we focus on the growing interest in two-dimensional MOFs as a practical HER/OER/NRR/CO 2 RR catalyst. We also consider its exciting value as a tool for probing the underlying reaction mechanism and catalytic function of various metals.

“…[28][29][30][31][32] In 2005, Yaghi and co-workers, for the first time, synthesized two pure two-dimensional (2D) organic frameworks, named COF-1 and COF-5. [33] Subsequently, a great variety of COFs with various structures have emerged and their applications in energy storage, [34][35][36][37] drug delivery, [38] adsorption, [39] separation, [40] catalysis, [41,42] optoelectronics [43,44] and sensing [45] have been widely investigated. Recently, scientists found that COFs show excellent electrochemical performance in rechargeable batteries by taking advantage of featured porous networks and tunable redox properties.…”

As the world moves toward electromobility, our daily lives are flooded with variety of lithium ion batteries (LIBs), and the concerns of cost, safety and environmental friendliness of LIBs spring up in the minds of scientists. Although organic electrodes have been considered as promising alternatives to their inorganic counterparts, some intrinsic weaknesses still plague scientists, such as high solubility, low conductivity and sluggish ion diffusion. The emergence of covalent organic frameworks (COFs) attracts our attention because of their robust networks and open pores that could facilitate the infiltration of electrolyte ions when used as electrodes for metal-ion batteries (MIBs). In this review, we summarized the recent progress of COFs as electrode materials, and the strategies toward enhancing electrochemical performance of COFbased electrode in MIBs are discussed. Hopefully, this review will provide a fundamental guidance for future development of COF-based electrodes.
