Developing highly efficient, affordable and renewable electrocatalysts is greatly important for large-scale production of hydrogen. MoS2 has been regarded as a promising electrocatalyst for hydrogen evolution reaction (HER), and foreign atom doping and forming heterogeneous structure have been proved to be the efficient ways to improve its electrocatalytic performance. In this paper, Cu doped MoS2 nanosheets supported on NiS2 (Cu-MoS2/NiS2) nanowires are prepared via the electrospinning, sulfuration and subsequent hydrothermal process. Benefitting from the heterointerfaces between MoS2 and NiS2 and the introduction of Cu into MoS2, the as-synthesized Cu-MoS2/NiS2 hybrid nanowires possess more electrocatalytic active sites and a favorable synergistic effect compared to the MoS2 nanosheets, NiS2 nanowires and MoS2/NiS2 hybrid structure. The Cu-MoS2/NiS2 hybrid nanowires exhibit an excellent HER performance with a low overpotential of 56 mV at 10 mA/cm2 and a small Tafel slope of 49 mV/dec in 0.5 M H2SO4. It is a potential substitute for noble metal electrocatalysts in the future. © 2023, The Authors. All rights reserved.

Developing highly efficient, low cost and stable bifunction electrocatalyst has become a greatly important direction of the widely application of overall water splitting. Herein, we have designed and prepared a composite material consisting of a Co(OH)2 film on a Fe-Ni alloy sheet supported by a Ni foam layer. The achieved catalysts expose abundant active sites, and exhibit excellent catalytic performance for both OER and HER in alkaline medium. The catalyst achieves a current density of 10 mA cm-2 only requires an overpotential of 218 mV for OER, which is lower than that of commercial RuO2 (276 mV). Similarly, it also exhibits excellent HER activity, the overpotential only needs 174 mV to obtain a current density of -10 mA cm-2, and with a low Tafel slope. Moreover, an electrolyzer voltage of 1.63 V corresponding to 10 mA cm-2 is obtained for 2D/2D Co(OH)2/Fe-Ni/NF nanosheets in a double electrode system. © 2023, The Authors. All rights reserved.

As a promising alternative to platinum, molybdenum disulﬁde (MoS2) is widely utilized as catalyst/co-catalyst in hydrogen evolution reaction (HER). However, its inactive basal plane greatly hampers its catalytic activity. Herein, we propose a function-oriented strategy to enhance the catalytic activity of MoS2 by interfacing with fullerene derivatives, specifically indene-C60 bisadduct (ICBA). The ICBA-MoS2 hybrid was then employed as an efficient co-catalyst, in conjunction with CdS, to construct a photocatalyst for solar-driven hydrogen production coupled with the selective oxidation of furfural alcohol (FOL) to furfural (FAL). The optimized 5% ICBA-MoS2/CdS (5%-IMC) sample exhibits a remarkable H2 and FAL production rates of 978 and 1160 μmol h-1 g-1, respectively, which was 2.4 times higher than that of the primitive sample without ICBA modified. This prominent catalytic performance can be attributed to the high activity of synergistic active sites in ICBA-MoS2, as well as the speed transportation and separation of the photogenerated charges from CdS to ICBA-MoS2, as evidenced by both experimental and theoretical investigations. © 2023, The Authors.

The perturbation in the environment by the discharge of toxic dyes in wastewater is a matter of concern and there is an urgent need to impart the balance. These organic dyes can be removed via catalytic degradation, adsorption or membrane filtration. In this study, we have developed a Zn(II)-based coordination polymer (CP) [Zn(bpyp)(HL-NO2)2]n (1) by solvothermal method using 2,5-bis(pyrid-4-yl)pyridine (bpyp) and 4-nitrobenzoic acid (HL-NO2) as organic linkers. The single crystal X-ray diffraction depicts that the Zn(II) adopts a tetragonal coordination environment and 1D linear chains are linked together to form a 2D framework via hydrogen bonding and π-π interactions. Methyl orange (MO), methyl violet (MV), methyl blue (MB) and rhodamine B (RhB) were investigated for photocatalytic degradation in the presence of visible light. Synthesized 1 shows 82% degradation of RhB dye. The Hirshfeld surfaces study demonstrated that these synthesized coordination polymers contain various forms of intermolecular contacts (C⋯C, H⋯C, H⋯H, and O⋯H). © 2023 Elsevier Inc.

In this work, the valence states and optical properties of chromium-doped Mg2GeO4 are investigated via first-principles methods. The formation energy and thermal charge transition level show that the site occupation and valence states of chromium are strongly related to the growth condition: Cr3+ dominates in the Mg sites under Mg poor conditions and Cr4+ dominates in the Ge sites under Ge poor conditions. With the lithium co-doped, the Fermi-level is pinned below the midgap, and the formation energy of chromium-doped Mg sites becomes lowest whatever under Mg-poor or Ge-poor condition, introducing that the co-doping of lithium ions promotes the chromium to occupy Mg sites with priority, in good agreement with experiments. Furthermore, the excitation and emission process of chromium ions are investigated, and our results recommend that the near-infrared emission is related to the 4T2 to 4A2 transition of Cr3+ at the Mg sites and the infrared emission is related to the 3T2-3A2 transition of Cr4+ at the Ge site. Our results help to understand the stability of the valence states of chromium ions doped Mg2GeO4 and the effects of co-doping regulating the chromium valence states, as well as the corresponding optical properties of different types of chromium ions. © 2023, The Authors.

The organic fluorescent probes were widely explored for specific detection of chemical nerve agent simulants. However, the fluorescence quenching, long-time response, and limitation of detection further impeded their practical applications. Herein, the fluorescent nanofiber chitosan-1 was prepared through the modification of chitosan with 1,8-naphthalimide as fluorophore and piperazine as the detection segment. The high specific surface of fluorescent nanofiber chitosan-1 showed ultrasensitive and selective detection of diethyl chlorophosphate (DCP) in solution and vapor. The satisfied linear relationship between the fluorescent intensity and the concentration of DCP ranging from 0 μmol/L to 100 μmol/L was obtained. The limitation of detection was measured as low as 2.2 nmol/L within 30 s. The sensing mechanism was explored through the photoinduced electron transfer (PET) mechanism which was confirmed by ¹H, ³¹P NMR, and mass spectra (MS). The ultrasensitive detection of nanofibers may provide valuable insights for enhancing the sensing performance in visually detecting chemical nerve agents. © 2025

A uniformly dispersed nano Silver sol was synthesized rapidly by visible light reduction method using AgNO3 as precursors, methyldiethanolamine (MDEA) as reducing agent, polyvinylpyrrolidone (PVP) as protective agent. The effects of Illumination time, concentration of each reactant on the formation rate and dispersion of nano-silver were investigated. The size, shape and dispersion of nano-silver particles were characterized by UV-Vis spectroscopy, and transmission electron microscopy, respectively. The results showed the nano-silver prepared was monodisperse regular spherical particles, size 5–10 nm and has no obvious changes kept in dark in a brown bottle for 6 months when it was prepared at the concentration of AgNO3 100 μg/mL, MDEA 250 μg/mL, PVP 500 μg/mL, photocurrent 15A at room temperature for 2 min. keywords: Nano silver sol, visible light reduction, green synthesis, technological optimization. © 2019, Springer Nature Singapore Pte Ltd.
