    Efficient blue-light-excitable copper(Ⅰ)coordination network phosphors for high-performance white LEDs

    查看更多>>摘要：The blue-light-excitable phosphors play a crucial role in the high-performance white LEDs.Here,we re-port on two new Cu(Ⅰ)coordination network materials as yellow-emitting phosphors prepared by suit-ably expanded π-conjugated triazole ligands.Upon blue-light irradiation,these complexes exhibit effi-cient solid-state emission and enhanced photostability.Through incorporating the yellow phosphor and a commercial blue-green powder(BaSi2N2O2:Eu2+)with a blue LED chip,the phosphor-converted LED de-vices display remarkable white emission properties.The experimental results demonstrate that the Cu(I)coordination network materials function as promising blue-light excitable phosphors with great applica-tion potential for full-spectrum white LEDs.

    Role of polarization evolution in the hysteresis effect of Pb-based antiferroelecrtics

    查看更多>>摘要：The electric field-induced irreversible domain wall motion results in a ferroelectric(FE)hysteresis.In an-tiferroelectrics(AFEs),the irreversible phase transition is the main reason for the hysteresis effects,which plays an important role in energy storage performance.Compared to the well-demonstrated FE hysteresis,the structural mechanism of the hysteresis in AFE is not well understood.In this work,the underlying correlation between structure and the hysteresis effect is unveiled in Pb(Zr,Sn,Ti)O3 AFE system by using in-situ electrical biasing synchrotron X-ray diffraction.It is found that the AFE with a canting dipole con-figuration,which shows a continuous polarization rotation under the electric field,tends to have a small hysteresis effect.It presents a negligible phase transition,a small axis ratio,and electric field-induced lattice changing,small domain switching.All these features together lead to a slim hysteresis loop and a high energy storage efficiency.These results offer a deep insight into the structure-hysteresis relationship of AFEs and are helpful for the design of energy storage material.

    Surface tension of single suspended aerosol microdroplets

    520-524页
    查看更多>>摘要：The surface tension of troposphere aerosols can significantly influence their atmospheric processes and key properties,particularly on the morphology,the phase transition,the activation as cloud condensa-tion nuclei,and the gas-particle partitioning.However,directly measuring the surface tension of single ambient aerosol is quite challenging,due to the limitations of their picolitre volumes and thermal mo-tion.Here,we developed a dual laser tweezers Raman spectroscopy(DLT-RS)system to directly sense the surface tension of single airborne microdroplets(PM10 particles).A pair of aerosol droplets were trapped and driven to coalesce by the laser tweezers.Meanwhile,the backscattering light intensity and bright-field images during the coalescence process were recorded to characterize the aerosol surface tension.A remarkable advantage of directly sensing aerosol surface tension is that the solutes in aerosols are of-ten supersaturated,which is common in atmospheric aerosols but almost unavailable in bulk solutions.We experimentally measured the surface tension of aerosols composed of nitrates or oxalic acid/nitrate mixture.Besides,the variation of surface tension during aerosol aging process was also explored,which brings possible implications on the surface evolution of actual ambient aerosol during their atmospheric lifetime.

    Phytic acid-derivative Co2B-CoPOx coralloidal structure with delicate boron vacancy for enhanced hydrogen generation from sodium borohydride

    查看更多>>摘要：Application of transition metal boride(TMB)catalysts towards hydrolysis of NaBH4 holds great signifi-cance to help relieve the energy crisis.Herein,we present a facile and versatile metal-organic framework(MOF)assisted strategy to prepare Co2B-CoPOx with massive boron vacancies by introducing phytic acid(PA)cross-linked Co complexes that are acquired from reaction of PA and ZIF-67 into cobalt boride.The PA etching effectively breaks down the structure of ZIF-67 to create more vacancies,favoring the maxi-mal exposure of active sites and elevation of catalytic activity.Experimental results demonstrate a drastic electronic interaction between Co and the dopant phosphorous(P),thereby the robustly electronega-tive P induces electron redistribution around the metal species,which facilitates the dissociation of B-H bond and the adsorption of H2O molecules.The vacancy-rich Co2B-CoPOx catalyst exhibits scalable per-formance,characterized by a high hydrogen generation rate(HGR)of 7716.7 mL min-1 g-1 and a low activation energy(Ea)of 44.9kJ/mol,rivaling state-of-the-art catalysts.This work provides valuable in-sights for the development of advanced catalysts through P doping and boron vacancy engineering and the design of efficient and sustainable energy conversion systems.

    Hexagonal boron nitride based slippery liquid infused porous surface with anti-corrosion,anti-contaminant and anti-icing properties for protecting magnesium alloy

    查看更多>>摘要：In an era where the concept of green development is deeply rooted,magnesium(Mg)alloy as a light metal has a long-term development prospect in the process of energy saving,emission reduction and environmental improvement.However,anti-corrosion performance of Mg alloy is poor due to the high chemical activity and low equilibrium potential,which limits the development of Mg alloy products.Herein,three-dimensional mesopore hollow polypyrrole spheres(MHPS)were prepared,and the MHPS was inserted into the middle of the stacked hexagon boron nitride(h-BN)lamellae,which allowed the h-BN to be separated forming a further composite with abundant pore structure.Subsequently,the MHPS/h-BN-OH composite was uniformly sprayed on the Mg alloy surface via simple spraying method to form the superhydrophobic surface(SHS).Finally,the slippery liquid infused porous surface(SLIPS)was success-fully fabricated by applying drops of silicone lubricant on the superhydrophobic coating surface.After a series of characterization and testing,the results showed that the stacking of h-BN lamellae was signifi-cantly reduced after h-BN was successfully embedded by MHPS.In addition,the fabricated SLIPS have ex-cellent self-cleaning,mechanical stability,anti-icing and anti-corrosion properties.Therefore,the method of embedding polymer microspheres not only offers a new strategy for h-BN exfoliation,but also the successful prepared SLIPS largely retards the corrosion of Mg alloy while providing new ideas for the development of SLIPS.

    One-step conversion of methane and formaldehyde to ethanol over SA-FLP dual-active-site catalysts:A DFT study

    544-548页
    查看更多>>摘要：One-step conversion of methane and formaldehyde into ethanol is a 100％atom-efficient process for car-bon resources utilization and environment protection but still faces eminent challenges due to the lack-ing of efficient catalysts.Therefore,developing active and stable catalysts is crucial for the co-conversion of methane and formaldehyde.Herein,twelve kinds of"Single-Atom"-"Frustrated Lewis Pair"(SA-FLP)dual-active-site catalysts are designed for the direct conversion of methane and formaldehyde to ethanol based on density functional theory(DFT)calculations and microkinetic simulations.The results show that the SA-FLP dual active sites can simultaneously activate methane at the SA site and activate formalde-hyde at the FLP site.Among the twelve designed SA-FLP catalysts,Fe1-FLP shows the best performance in the co-conversion of methane and formaldehyde to ethanol with the rate-determining barrier of 1.15 eV.Ethanol is proved as the main product with the turnover frequency of 1.32 × 10-4 s-1 at 573K and 3 bar.This work provides a universal strategy to design dual active sites on metal oxide materials and offers new insights into the effective conversion of methane and formaldehyde to desired C2 chemicals.
