Hierarchical porous activated carbon fibers with a BET surface area of 2231 m2 g−1 and pore volume 1.16 cm3 were made from polyacrylonitrile through pre-oxidation chemical activation. This type material contains large amount nitrogen-containing groups (N content > 8.1 wt%) consequently basic sites, resulting in faster adsorption rate higher capacity for CO2 than pure materials analogous structures under the same conditions. Moreover, its was more 3.3-times that N2. In particular, it showed...
Abstract A hierarchical microporous carbon material with a Brunauer–Emmett–Teller surface area of 1348 m 2 g −1 and pore volume 0.67 cm 3 was prepared from yeast through chemical activation potassium hydroxide. This type contains large numbers nitrogen‐containing groups (nitrogen content >5.3 wt %), and, consequently, basic sites. As result, this shows faster adsorption rate higher capacity CO than the obtained by directly carbonizing under same conditions. The difference is more...
Abstract A high yield spinnable pitch for isotropic pitch‐based carbon fiber was successfully prepared by air oxidation polycondensation of asphaltene with styrene‐ethylene‐butylene‐styrene. The effects reaction temperature and time, added styrene‐ethylene‐butylene‐styrene amount on the composition spinning properties resultant pitches were investigated. a concentrated molecular weight distribution 300–700 Da at 340 ° C 3 h under blowing 5% styrene‐ethylene‐butylene‐styrene, moreover, its...
Noble metals have become a research hotspot for the oxidation of light alkanes due to their low ignition temperature and easy activation C-H; however, sintering high price limit industrial applications. The preparation effective low-noble-metal catalysts still presents profound challenges. Herein, we describe how Ru@CoMn2O4 spinel catalyst was synthesized via Ru in situ doping promote activity propane oxidation. exhibited much higher catalytic than CoMn2O4, achieving 90% conversion at 217...
We report on the photocurrent properties of hydrogenated nanocrystalline silicon (nc-Si:H) thin film/crystalline (c-Si) n-p heterostructure. By comparison with c-Si homojunction, two Gaussian-type peaks are observed in nc-Si:H/c-Si heterostructure and attributed to be transitions from a tail band or discrete levels quantum dots localized states, miniband extended states associated embedded nanometer crystallites amorphous boundaries nc-Si:H film. The strong signals temperature dependency...
The effects of a single basal fertilization with oxamide compared those split application urea on ammonia volatilization, rice yield, nitrogen (N) accumulation, and N use efficiency were investigated in field experiment over 2 years. study consisted two fertilizers (oxamide urea) applied at 157.5 225 kg ha−1 no-N Control. Compared urea, the produced similar yields reduced approximately 38.3% to 62.7% lost through volatilization 2013 2014. Oxamide rate resulted greater aboveground...
Doping of silicon nanocrystals (Si-NCs) is one the major challenges for nanoscale devices. In this work, phosphorus (P) doping in Si-NCs which are embedded within an amorphous matrix realized together with growth by plasma-enhanced chemical vapor deposition under a tunable substrate direct current (DC) bias. The variation concentration bias can be explained competition bonding processes Si-Si and P-Si bonds. formation bonds differently influenced ion bombardment controlled bias, due to their...
ZnO nanorods are fabricated on glass substrate by spin-coating sol-gel process using non-basic aged solution and annealing. Sample solutions reserved in room temperature for different time (one day, one month, two months four months) prepared the experiment. The morphology study indicates that aging has direct influence final products. This is verified Transmission Electron Microscopy Photon Correlation Spectroscopy study. Small crystalline nanoparticles would gradually nucleate aggregate...
The influence of the type support [activated carbon (AC), HZSM‐5, and γ‐Al 2 O 3 ] on performance Ni‐based catalysts for catalytic hydrogenolysis (CH) benzyl phenyl ether (BPE) is investigated. properties an catalyst are investigated using diverse characterization techniques. An Ni/AC exhibits highest dispersion Ni atoms by CO pulse. kinetic studies show that apparent activation energies ( E a ) CH BPE increase in order (Ni/AC) < (Ni/γ‐Al (Ni/HZSM‐5), initial turnover frequencies follow...
