Two-dimensional (2D) transition metal chalcogenides (TMCs) hold great promise as novel microwave absorption materials owing to their interlayer interactions and unique magnetoelectric properties. However, overcoming the impedance mismatch at low loading is still a challenge for TMCs due restricted loss pathways caused by high-density characteristic. Here, an interface engineering based on heterostructure of 2D Cr
CoNi LDH-6 with a nano-petal structure was prepared, which exhibited excellent rate performance and long-term stability as supercapacitor electrode.
Flexible and lightweight supercapacitors with satisfactory energy density long-term stability are urgently required to provide power for flexible, foldable, wearable electronic devices. Herein, reedlike carbon nanofibers (RCNFs) hierarchical macropores in the core micropores honeycomb mesopores shell designed by electrospinning, carbonization, etching, leading high conductivity mechanical flexibility foldability. Subsequently, flowerlike Ni–Co–S nanoarrays grown situ on RCNFs...
The effect of reducing particle size on physical properties, the methane yield and energy flow were investigated through biochemical potential (BMP) experiment aerobic-anaerobic digestion (AAD) rice straw (RS). whole was crushed four sieves different aperture sizes (1, 3, 5, 7 mm) to obtain actual non-uniform distribution (PSD). results indicated that normally or logarithmic distributed. Reducing could significantly promote aerobic hydrolysis acidification process, increase content volatile...
Bio-oil can be used as a substitute for fossil fuels after it is upgraded. Bimetal-modified HZSM-5 catalysts with various Ni-to-Co ratios were prepared to address catalysis problems, including deactivation of the and low hydrocarbon yields. The catalytic performance Ni-Co/HZSM-5 in upgrading simulated bio-oil was investigated fixed-bed reactor, influence loaded duplex metal ratio also discussed. new moderately strong/strong acid sites changed according Ni/Co loading ratios, which...
Abstract Although graphene fiber‐based supercapacitors are promising for wearable electronic devices, the low energy density of electrodes and poor cold resistance aqueous electrolytes limit their wide application in environments. Herein, porous nitrogen/sulfur dual‐doped fibers (NS‐GFs) synthesized by hydrothermal self‐assembly followed thermal annealing, exhibiting an excellent capacitive performance 401 F cm −3 at 400 mA because synergistic effect heteroatom dual‐doping. The assembled...
Slow pyrolysis of industrial waste lignin has been carried out in a lab-scale tube furnace reactor at 300–700°C, and the effect temperature on yields character pyrolytic products (bio-char, bio-oil gas) was investigated. The results showed that played an important role conversion into high value-added products. Bio-char dominant product lignin, whose quality improved with increasing temperature, while best combustion reactivity focus 500°C. optimum condition for formation 600°C, where...
Pyrolysis experiments of pine nut shells (PNSs) were carried out in a screw reactor at 300–700°C with approximately 98% energy yields. The analysis results showed that higher temperatures result elevated heating values (HVs) products but reduced biochar and bio-oil HVs pyrolytic gas remarkably influenced by proportions CH4 H2. Bio-oil PNSs consisted primarily phenols, acids, aldehydes, ketones, furans, aromatic hydrocarbons. Five hundred degree Celsius was considered as optimal temperature...
Chemical pretreatment can significantly improve the enzymatic hydrolysis efficiency of lignocellulosic biomass, thereby improving yield sugar materials for production cellulosic ethanol, but commonly used acid–base catalysts are difficult to recover and reuse. In this work, a combination method liquid hot water (LHW) phosphotungstic acid (PTA) was performed saccharification rice straw, we attempted evaluate reuse effect PTA catalysts. The straw first treated with LHW at 180 °C 90 min, then...
Creep tests were conducted on a nanocrystalline Cu at room temperature. The results very low strain rates (<4×10−8 s−1) are consistent with Coble creep. An overall view of stress-strain rate behavior this indicates that as the decreases, deformation mechanism transition from predominantly dislocation activity to diffusion creep, evidenced by sensitivity stress trending m=1 and activation volume υ=1.5b3. typical m=0.5 for surperplasticity can hardly be obtained such homogenous
