| 2 | Advanced Ni-Nx-C single-site catalysts for CO2 electroreduction to CO based on hierarchical carbon nanocages and S-doping显示文摘Metal-nitrogen-carbon materials are promising catalysts for CO2 electroreduction to CO. Herein, by taking the unique hierarchical carbon nanocages as the support, an advanced nickel-nitrogen-carbon single-site catalyst is conveniently prepared by pyrolyzing the mixture of NiCl2 and phenanthroline, which exhibits a Faradaic efficiency plateau of > 87% in a wide potential window of −0.6 – −1.0 V. Further S-doping by adding KSCN into the precursor much enhances the CO specific current density by 68%, up to 37.5 A·g−1 at −0.8 V, along with an improved CO Faradaic efficiency plateau of > 90%. Such an enhancement can be ascribed to the facilitated CO pathway and suppressed hydrogen evolution from thermodynamic viewpoint as well as the increased electroactive surface area and improved charge transfer fromkinetic viewpoint due to the S-doping. This study demonstrates a simple and effective approach to advanced electrocatalysts by synergetic modification of the porous carbon-based support and electronic structure of the active sites. | Yiqun Chen Yuejian Yao Yujian Xia Kun Mao Gongao Tang Qiang Wu Lijun Yang Xizhang Wang Xuhui Sun Zheng Hu | 2020 | Nano Research2020，13，10： | 8 |
| 3 | Understanding the electrode reaction process of dechlorination of 2,4-dichlorophenol over Ni/Fe nanoparticles: Effect of pH and 2,4-dichlorophenol concentration显示文摘Herein,with the exploitation of iron and nickel electrodes,the 2,4-dichlorophenol(2,4-DCP)dechlorinating processes at the anode and cathode,respectively,were separately studied via various electrochemical techniques(e.g.,Tafel polarization,linear polarization,electrochemical impedance spectroscopy).With this in mind,Ni/Fe nanoparticles were prepared by chemical solution deposition,and utilized to test the dechlorination activities of 2,4-DCP over a bimetallic system.For the iron anode,the results showed that higher 2,4-DCP concentration and solution acidity aggravated the corrosion within the electrode.The charge transfer resistance(Rct)values of the iron electrode were 703,473,444,and 437Ω·cm2 for the initial 2,4-DCP concentrations of0,20,50,and 80 mg/L,respectively.When the bulk pH of the 2,4-DCP solution varied from 3.0,5.0to 7.0,the corresponding Rct values were 315,376,and 444Ω·cm2,respectively.For the nickel cathode,the reduction current densities on the electrode at-0.75 V(vs.saturated calomel electrode)were 80,106,and 111μA/cm2,for initial 2,4-DCP concentrations of 40,80,and125 mg/L.The dechlorination experiments demonstrated that when the initial pH of the solution was 7.0,5.0,and 3.0,the dechlorination percentage of 2,4-DCP by Ni/Fe nanoparticles was 62%,69%,and 74%,respectively,which was in line with the electrochemical experiments.10 wt.%Ni loading into Ni/Fe bimetal was affordable and gave a good dechlorination efficiency of 2,4-DCP,and fortunately the Ni/Fe nanoparticles remained comparatively stable in the dechlorination processes at pH 3.0. | Kaiyuan Zheng Yuqiao Song Xu Wang Xin Li Xuhui Mao Dihua Wang | 2019 | Journal of Environmental Sciences2019，31，10： | 2 |
| 4 | The capacitive performances of carbon obtained from the electrolysis of CO_(2) in molten carbonates: Effects of electrolysis voltage and temperature显示文摘The electrochemical reduction of CO2 to capacitive carbon in molten Li2 CO3–Na2 CO3–K2 CO3 is an effective strategy for capturing and utilizing CO2. This paper reports the effects of the cell voltages and operating temperatures(450–650 °C) of the molten salt electrolysis on the capacitive performance of electrolytic carbon. The electrolytic carbon delivers excellent specific capacitance when the cell voltage is 4.5 V and the temperature of molten salt is 450 °C. The carbon obtained at 450 °C and under 4.5 V delivers a specific capacitance of 550 F g^(-1) at 0.2 A g^(-1) in 1 M aqueous H2 SO4, and the capacity retention rate is73% after 10000 cycles. The specific capacitance of the electrolytic carbon increases as the electrolysis temperature decreases, and the optimal cell voltage is 4.5 V. | Diyong Tang Yanpeng Dou Huayi Yin Xuhui Mao Wei Xiao Dihua Wang | 2020 | Journal of Energy Chemistry2020，29，12： | 2 |
| 5 | Alternating Pulse Current in Eiectrocoagulation for Wastewater Treatment to Prevent the Passivation of Al Electrode显示文摘A novel current feed style,alternating pulse current,was proposed in electrocoagulation aiming at preventing the passivation of electrode materials.The open circuit potential(OCP)measurements after anodic and cathodic potentiodynamic polarization showed that cathodic polarization could activate Al electrode.The surface of Al electrode after alternating pulse current electrocoagulation was investigated by scanning electron microscope(SEM)and X-ray photoelectron spectroscopy(XPS),and the results indicate that passivation of Al is not observed.Furthermore,the simulated wastewater treatment tests show that alternating pulse current electrocoagulation has a visible energy saving effect and is worthy of generalization. | MAO Xuhui HONG Song ZHU Hua LIN Hui WEI Lin GAN Fuxing | 2008 | Journal of Wuhan University of Technology(Materials Science)2008，23，2： | 2 |
| 6 | Physics-informed neural networks with residual/gradient-based adaptive sampling methods for solving partial differential equations with sharp solutions显示文摘We consider solving the forward and inverse partial differential equations(PDEs)which have sharp solutions with physics-informed neural networks(PINNs)in this work.In particular,to better capture the sharpness of the solution,we propose the adaptive sampling methods(ASMs)based on the residual and the gradient of the solution.We first present a residual only-based ASM denoted by ASMⅠ.In this approach,we first train the neural network using a small number of residual points and divide the computational domain into a certain number of sub-domains,then we add new residual points in the sub-domain which has the largest mean absolute value of the residual,and those points which have the largest absolute values of the residual in this sub-domain as new residual points.We further develop a second type of ASM(denoted by ASMⅡ)based on both the residual and the gradient of the solution due to the fact that only the residual may not be able to efficiently capture the sharpness of the solution.The procedure of ASMⅡis almost the same as that of ASMⅠ,and we add new residual points which have not only large residuals but also large gradients.To demonstrate the effectiveness of the present methods,we use both ASMⅠand ASMⅡto solve a number of PDEs,including the Burger equation,the compressible Euler equation,the Poisson equation over an Lshape domain as well as the high-dimensional Poisson equation.It has been shown from the numerical results that the sharp solutions can be well approximated by using either ASMⅠor ASMⅡ,and both methods deliver much more accurate solutions than the original PINNs with the same number of residual points.Moreover,the ASMⅡalgorithm has better performance in terms of accuracy,efficiency,and stability compared with the ASMⅠalgorithm.This means that the gradient of the solution improves the stability and efficiency of the adaptive sampling procedure as well as the accuracy of the solution.Furthermore,we also employ the similar adaptive sampling technique for the data points of boundary conditions(BCs)if the sharpness of the solution is near the boundary.The result of the L-shape Poisson problem indicates that the present method can significantly improve the efficiency,stability,and accuracy. | Zhiping MAO Xuhui MENG | 2023 | Applied Mathematics and Mechanics(English Edition)2023，44，7： | 1 |

| 9 | Enhanced electrochemical oxidation of phenol by introducing ferric ions and UV radiation显示文摘The mineralization of phenol in aerated electrochemical oxidation has been investigated.The results show that a cathodic Fenton process can occur when the Ti-0.3Mo-0.8Ni alloy material is used as cathode in solution containing ferric or ferrous ions; moreover,the reinforcement of cathodic Fenton process on the total organic carbon (TOC) removal rate of phenol is quite distinct.Among the metallic ions investigated,the ferric ion is the best catalyst for the electrochemical mineralization of phenol at initial pH 2.0,and the optimal concentration range is from 50 to 200 mg/L.The favorable pH range and supporting electrolyte (Na2SO4) concentration for mineralization of phenol in solution containing ferrous ions are 1.8-2.3 and below 0.10 mol/L,respectively.UV radiation can improve the TOC removal rate of phenol,but the enhanced effect varies in different solutions.In the solution containing ferric ions,an equal sum or synergetic effect can be observed.The optimal effect of electrolysis system under UV radiation is achieved in the solution containing 50 mg/L Fe3+ with a final removal percentage of 81.3%. | MAO, Xuhui WEI, Lin HONG, Song ZHU, Hua LIN, An GAN, Fuxing | 2008 | Journal of Environmental Sciences2008，20，11： | 1 |
| 10 | Combination of steam-enhanced extraction and electrical resistance heating for efficient remediation of perchloroethylene-contaminated soil:Coupling merits and energy consumption显示文摘In situ thermal desorption(ISTD)technology effectively remediates soil contaminated by dense nonaqueous phase liquids(DNAPLs).However,more efforts are required to minimize the energy consumption of ISTD technology.This study developed a laboratory-scale experimental device to explore the coupling merits of two traditional desorption technologies:steam-enhanced extraction(SEE)and electrical resistance heating(ERH).The results showed that injecting high-density steam(>1 g/min)into loam or clay with relatively high moisture content(>13.3%)could fracture the soil matrix and lead to the occurrence of the preferential flow of steam.For ERH alone,the electrical resistance and soil moisture loss were critical factors influencing heating power.When ERH and SEE were combined,preheating soil by ERH could increase soil permeability,effectively alleviating the problem of preferential flow of SEE.Meanwhile,steam injection heated the soil and provided moisture for maintaining soil electrical conductivity,thereby ensuring power stability in the ERH process.Compared with ERH alone(8 V/cm)and SEE alone(1 g/min steam),the energy consumption of combined method in remediating perchloroethylene-contaminated soil was reduced by 39.3%and 52.9%,respectively.These findings indicate that the combined method is more favorable than ERH or SEE alone for remediating DNAPL-contaminated subsurfaces when considering ISTD technology. | Rui Yue Zhikang Chen Liujun Liu Lipu Yin Yicheng Qiu Xianhui Wang Zhicheng Wang Xuhui Mao | 2022 | Frontiers of Environmental Science & Engineering2022，16，11： | 1 |
| 11 | Kinetics process for structure-engineered integrated gradient porous paper-based supercapacitors with boosted electrochemical performance显示文摘Due to their rich and adjustable porous network structure,paper-based functional materials have become a research hotspot in the field of energy storage.However,reasonably designing and making full use of the rich pore structure of paper-based materials to improve the electrochemical performance of paper-based energy storage devices still faces many challenges.Herein,we propose a structure engineering technique to develop a conductive integrated gradient porous paper-based(CIGPP)supercapacitor,and the kinetics process for the influence of gradient holes on the electrochemical performance of the CIGPP is investigated through experimental tests and COMSOL simulations.All results indicate that the gradient holes endow the CIGPP with an enhanced electrochemical performance.Specifically,the CIGPP shows a significant improvement in the specific capacitance,displays rich frequency response characteristics for electrolyte ions,and exhibits a good rate performance.Also,the CIGPP supercapacitor exhibits a low self-discharge and maintains a stable electrochemical performance in different electrolyte environments because of gradient holes.More importantly,when the CIGPP is used as a substrate to fabricate a CIGPP-PANI hybrid,it still maintains good electrochemical properties.In addition,the CIGPP supercapacitor also shows excellent stability and sensitivity for monitoring human motion and deaf-mute voicing,showing potential application prospects.This study provides a reference and feasible way for the design of structure-engineered integrated paper-based energy storage devices with outstanding comprehensive electrochemical performance. | Chuanyin Xiong Yongkang Zhang Jiayu Xu Weihua Dang Xuhui Sun Meng An Yonghao Ni Junjie Mao | 2023 | Nano Research2023，16，7： | 1 |
