Abstract Sintering of active metal species often happens during catalytic reactions, which requires redispersion in a reactive atmosphere at elevated temperatures to recover the activity. Herein, we report simple method redisperse sintered Cu catalysts via O 2 -H treatment room temperature. In-situ spectroscopic characterizations reveal that H induces formation hydroxylated humid , pushing surface diffusion atoms Further, OH groups formed on most hydroxylable support surfaces such as γ-Al 3...
Magnesium alloys with homogeneous degradation and controlled rate are desirable for biodegradable materials. In the present work, Mg-3 wt.%Zn-0.2 wt.%Ca different columnar structures were fabricated in 0.9 wt.% NaCl investigated. With increase of growth directional solidification, microstructure directionally solidified (DSed) alloy evolved from cellular to dendritic coupled change spacing primary trunks (λ1) volume fraction (fv) Ca2Mg6Zn3 phase. The results corrosion test suggested that...
Supported metal catalysts are widely used for chemical conversion, in which construction of high density metal-oxide or oxide-metal interface is an important means to improve their reaction performance. Here, Cu@ZnO
The mechanical properties and degradation performance in Hank's solution of the directionally solidified (DSed) Mg−0.8Ca (wt.%) alloys were investigated compared with those as-cast alloy. microstructure was studied by OM, SEM, TEM, EBSD. It is found that columnar grains DSed have a consistent growth orientation <1120>. strength ductility alloy are significantly improved after directional solidification. Besides, corrosion resistance dramatically enhanced mainly undergo microgalvanic...
The formation of non-dendritic structure Mg alloy solidified with ultrasonic treatment was investigated by numerical simulation and experiment. models nucleation crystal growth involved the effects cavitation acoustic streaming were built. Based on models, grain refinement microstructure change from dendrite to a Mg-Al numerically simulated cellular automata method. experimental results indicated that strongly contributes improving nucleation, while is mainly responsible for structure.
Supported metal or oxide nanostructures catalyze many industrial reactions, where the interaction of overlayer with its support can have a substantial influence on catalytic performance. In this work, we show that small Pt species be well stabilized CeO2 under both H2-containing and O2-containing atmospheres but sintering happens SiO2, indicating is active whereas SiO2 inert in Pt-support interaction. On other hand, Co (CoOx) supported maintain low-valence Co2+ state air during CO2...
Many oxide catalysts exhibit high selectivity but low conversion in CO2 hydrogenation due to strong adsorption, which often impedes H2 dissociation and subsequent hydrogenation. Herein, we report that a ZnCr2O4@ZnOx catalyst featuring monodispersed ZnOx overlayer confined on ZnCr2O4 facilitates activation without compromising activation. This demonstrates dual‐site mechanism surface and/or ZnOx/ZnCr2O4 interface provide sites for promote homolytic formation of stable metal‐H species,...

The solution treatment parameters, mechanical properties and corrosion behavior of binary Mg-4Zn alloy were investigated. results showed that after the at 335 °C for 16 h, had an ultimate tensile strength 184.13 MPa elongation 9.43%. Furthermore, resistance was evaluated by electrochemical measurements immersion tests in 3.5% NaCl solution. revealed current density Mg 11.2 µA/cm−2, it lower than 15.8 µA/cm−2 as-cast under same conditions, which greatly associated with micro-cathode effect...
SBP-box (Squamosa-promoter binding protein) genes are a type of plant-specific transcription factor and play important roles in plant growth, signal transduction stress response. However, little is known about the pepper (CaSBP), especially process Phytophthora capsici infection. In this study, novel gene (CaSBP12) was selected from CaSBP family, which isolated genome database our previous study. The CaSBP12 located nucleus cell its silencing enhanced defense response against After...
Organic amendment is an effective method to reclaim salt-affected soil. However, in coastal land with shallow saline groundwater, it limited known about the mechanism of organic on soil desalinization.
