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.

Nickel phosphide (Ni 2 P/C) hollow microspheres were synthesized via a facile two-step route based on metal-organic framework (MOF) precursors. Unlike direct phosphating the MOF by calcination that would damage the MOF structure and that would form multiple phases, solvothermal method was able to convert the Ni-based MOF to one-pure-phase nickel phosphide with the MOF skeleton maintained, as suggested by XRD, XPS, and SEM. When using as the battery-supercapacitor hybrids electrode material, the optimized Ni 2 P/C exhibited the specific capacity 670.4 C/g (1676 F/g) at 1 A/g in a threeelectrode system, and a maximum energy density 42.74 Wh/kg at 764.23 W/kg in an asymmetric supercapacitor. It also delivered an energy density of 35.39 Wh/kg at 7000 W/kg with the rate capability retention of 92 % after 5000 cycles. The high specific surface area and the increased amount of electrochemically active sites endowed by the unique morphology, together with the low charge transfer resistance all contribute to the excellent electrochemical performance of the Ni 2 P/C material. These also indicate that solvothermal method is feasible in converting MOF to metal phosphide for the application in energy storage and conversion systems.[a] Prof.

“…By contrast, colorimetric determination is widely used because of its low cost, easy operation and strong practicability. [4] In the past few years, two-dimensional molybdenum disulfide (2D MoS 2 ) as a graphene analogue has become an eye-attracting non-precious metal catalyst by virtue of abundance, economically efficient, non-toxicity, high chemical stability and catalytic activity for biosensor filed. [5] Unlike the structure of graphene, MoS 2 nanosheets can be seen as sandwich structures of SÀ MoÀ S with covalent bonding in-plane and weak van der Waals interaction between the layers.…”

Recently, nanozymes have attracted extensive attention because of their advantages of combining nanomaterials with enzymes. Herein, hexagonal boron nitride (h-BN) and nitride-doped molybdenum disulfide (NÀ MoS 2 ) nano-composites (h-BN/NÀ MoS 2 ) were synthesized by facile and cost-effective liquid exfoliation with a solvothermal method in nontoxic ethanol solution. The results show that h-BN, as a co-catalyst, can not only dope into the lattice of MoS 2 but also form a heterogeneous structure with MoS 2 NSs. It expanded the layer spacing and specific surface area of MoS 2 NSs, which was beneficial to the contact between the catalyst and the substrate, and resulted in a synergistic enhancement of the catalytic activity of hydrogen peroxide (H 2 O 2 ) with MoS 2 . A colorimetric determination platform of h-BN/NÀ MoS 2 -TMB-H 2 O 2 was constructed. It exhibited a wide linear range of 1-1000 μM with a low limit of detection (LOD) of 0.4 μM under optimal conditions, high sensitivity and stability, as well as good reliability (99.4-110.0%) in practice, making the measurement system more widely applicable.1.
