Electric vehicles and portable devices have increased their demand for energy storage,resulting in the development of new high energy density batteries,including solid-state lithium-metal batteries,lithium-oxygen(Li-O_(2))batteries and lithium-sulfur(Li-S)batteries,which utilize high-capacity materials and will significantly break through the dilemma faced by the commercially available lithium-ion batteries[1–3].

The purpose of this study is to increase acrolein yield and capability of coking resistance in the reaction of glycerol dehydration to acrolein by assembling metal phosphate supported on HZSM-5 catalyst. The as-prepared catalysts were characterized by XRD, SEM, EDS, BET, NH_3-TPD, CO_2-TPD and Py-IR techniques. It was found that metal phosphate species were incorporated into the porous structure of HZSM-5 zeolites, thus influencing the surface and textural physico-chemical properties of the supporters. The alkaline-treated HZSM-5 catalyst promoted the dispersion of phosphate species on the carriers. Moreover, the amount of strong acidity was tremendously improved by adding the different metal hydrophosphates and the catalysts show high catalytic activity. In this present work, the Sn1/4 H_2PO_4/HZSM-5 catalyst exhibited good performance in the catalytic activity and coking resistant ability, which resulted in a high acrolein yield of 83% initially and acrolein yield of 68% after 30 h. The acidity, especially the ratio of strong to weak acid, plays an important role in promoting acrolein yield and stability simultaneously.

Ag@Cu2O core-shell metal-semiconductor nanoparticles(NPs) were prepared by using solution phase strategy. It was found that Ag@Cu2O core-shell NPs were easily converted to Ag@Cu bimetallic core-shell NPs with the help of surfactant PVP and excessive reducer ascorbic acid in air at room temperature, which is a unique phenomenon. Varying volumes of Ag colloidal solutions were added into the reaction mixtures containing fixed initial concentrations of Cu2+ and PVP, Ag@Cu2O and Ag@Cu core-shell NPs with fixed core size but varying outer shell thicknesses could be obtained. The composites, structures, morphologies and extinction properties of Ag@Cu2O and Ag@Cu core-shell NPs were systematically characterized by XRD, TEM and extinction spectra. Both of these NPs show wide tunable optical properties. The extinction peaks could be shifted from 421 nm to 700 nm. FTIR results reveal that Cu+ ions on the surface of Cu2 O nanocrystalline coordinate with N and O atoms in PVP and further are reduced to metallic Cu by excessive ascorbic acid and then form a nucleation site on the surface of Cu2 O nanocrystalline. PVP binds onto a different site to proceed with the reduction until all the Cu sources in Cu2 O NPs are completely assumed. And the shell of Cu2 O is converted to Cu shell. The synthesis approach in this paper is simple and also a promising reference for synthesizing other core-shell NPs. Ag@Cu2O NPs can be easily converted to Ag@Cu NPs in air at room temperature, which is promising to be used in electronic devices.

Copper catalysts supported on metal oxides display unique efficiency and selectivity in catalyzing glycerol hydrogenolysis to propanediols. Understanding the reaction at the molecular level is the key to rational design of better catalysts for propanediol synthesis, which is one of the major challenges for glycerol application in energy. In this work, extensive calculations based on periodic density functional theory were carried out to study thermodynamics of glycerol hydrogenolysis over binary model catalysts, including Cu/ZrO2 and Cu/MgO, with the focus to elucidate the competitive reaction pathways to produce the 1,2-propanediol (1,2-PDO) and 1,3-propanediol (1,3-PDO). Our results suggest that the reaction starts with glycerol dehydration on the metal oxide, followed by sequential hydrogenation over metal centers. Based on our explorations on the stabilities of adsorbed reactants, dehydrated intermediates and hydrogenated species along the reaction channels, the DFT calculations show that the 1,2-PDO formation will dominate in comparison to the 1,3-PDO from thermodynamic viewpoint. This is consistent with our experiments where the Cu catalysts seem to give the 1,2-PDO as a main product. The calculations and experiments also indicate that the Cu/MgO exhibits superior activities than Cu/ZrO2 for the hydrogenolysis of glycerol molecules.

Electrolysis of ammonia in alkaline electrolyte solution was applied for the production of hydrogen. Both Pt-loaded Ni foam and Pt-Ir loaded Ni foam electrodes were prepared by electrodeposition and served as anode and cathode in ammonia electrolytic cell, respectively. The electrochemical behaviors of ammonia in KOH solution were individually investigated via cyclic voltammetry on three electrodes, i.e. bare Ni foam electrode, Pt-loaded Ni foam electrode and Pt-Ir loaded Ni foam electrode. The morphology and composition of the prepared Ni foam electrode were analyzed by scanning electron microscopy(SEM) and X-ray diffraction(XRD). Effects of the concentration of electrolyte solution and temperature of electrolytic cell on the electrolysis reaction were examined in order to enhance the efficiency of ammonia electrolysis. The competition of ammonia electrolysis and water electrolysis in the same alkaline solution was firstly proposed to explain the changes of cell voltage with the electrolysis proceeding. At varying current densities, different cell voltages could be obtained from galvanostatic *** low cell voltage of 0.58 V, which is less than the practical electrolysis voltage of water(1.6 V), can be obtained at a current density of2.5 mA/cm2. Based on some experimental parameters, such as the applied current, the resulting cell voltage and output of hydrogen gas, the power consumption per gram of H2produced can be estimated.

By stepwise adding of reducer N2H4.H2O, cuprous oxide （Cu2O） nanoparticles （NPs） with adjustable structures were synthe- sized. The features of Cu2O NPs were characterized by XRD, TEM and UV-Vis absorption spectra. When the reducer was added into the reactant system at one time, the sizes of the Cu2O NPs are in the range of 120-140 nm. Most Cu2O NPs are sol- id spheres. As the reducer was divided into two equal parts and stepwisely added, almost all the NPs are hollow spheres with good size （150-170 nm） distribution and dispersity. But when the reducer was divided into three or four equal parts and stepwisely added, the NPs are hollow spheres, core-shell structures or solid spheres, and the sizes distribution of the products is deteriorated. The effect of sodium hydrate （NaOH） was also probed. Addition of NaOH speeded up the nucleation and growth processes of Cu2O NPs. With the alkalinity increase, the shells of the hollow spheres become compact and the thicknesses of the shells increase, but the size distribution of the NPs is deteriorated. The absorption spectra of the CuzO NPs are tunable. With the shell thicknesses increase, the absorption peaks have red shifts. An inside-outside growth model of Cu2O NPs was proposed to explain the results. The Cu2O single crystalline grains grow not only in the reactant solution, but also inside of the hollow nanospheres. The new Cu2O nanocrystallines can not only aggregate onto the shells of the nano hollow spheres, but also inside and outside of the hollow spheres, which leads to increasing the shell thicknesses of the hollow spheres, forming core-shell structures or small solid spheres of Cu2O NPs, respectively.
