In this study, magnesium oxide (MgO)-modified carbon adsorbents were fabricated using a nitrogen-enriched precursor by microwave-assisted irradiation for CO2 capture. The X-ray diffraction (XRD) patterns showed the characteristic peaks of MgO at 43° and 62.5°, no impurities apparent. By changing microwave reaction time, spherical structure parent material was transformed to hybrid with crystalline particles in matrix. morphology evolution properties prepared materials also investigated...
Abstract A simple and scalable method to fabricate a yarn‐type supercapacitor with large specific capacitance without the aid of traditional pseudocapacitive electrode materials such as conducting polymers metal oxides is reported. The supercapacitors are made from twisting reduced graphene oxide (rGO) or/and single‐walled carbon nanotubes (SWNTs)‐coated Korean paper (KTP). displays surprisingly enhanced electrochemical values, showing synergistic effect between rGO SWNTs (500 times larger...
Activated carbon (AC) was synthesized with various weight ratios of manganese dioxide (MO) through a simple hydrothermal approach. The electrochemical performance the activated carbon/MnO2 composites investigated. effect (AM) ratio on properties and pore structure also examined. results show that specific capacitance material has been improved after addition MO. as-synthesized composite exhibits 60.3 F g−1 at 1 A g−1, as well stable cycle 99.6% retention over 5000 cycles.
Nanoporous materials have been developed as carbon dioxide (CO<sub>2</sub>)-capturing materials.
In this study, the modification of an epoxy matrix with different amounts cube-like and rod-like CaCO3 nanoparticles was investigated. The effects variations in morphology on mechanical properties thermal stability CaCO3/epoxy composites were studied. (EP-rod) showed a higher degradation temperature (4.5 °C) than neat epoxy. results that properties, such as flexural strength, modulus, fracture toughness enhanced by addition nanoparticles. Moreover, increasing amount added but decreased when...
Novel and effective reduced graphene oxide-nickel (Ni) doped manganese oxide (RGO/Ni-MnO2) adsorbents were fabricated via a hydrothermal approach. The reduction of graphite to (GO), formation α-MnO2, decoration Ni-MnO2 onto the surface (RGO) independently carried out by technique. physical morphological properties as-synthesized analyzed. Batch adsorption experiments performed identify lithium uptake capacities adsorbents. optimized parameters for Li+ investigated pH = 12, dose loading 0.1...
Solid-state supercapacitors have shown extraordinary promise for flexible and wearable electronics. To date, they are still limited by relatively poor energy volumetric performances, which largely determined the pore structures physicochemical properties of electrode materials. Moreover, mechanical afforded because intrinsic shortcomings materials need to be resolved. Herein, we designed a solid-state yarn with high porosity affinity toward electrolytes using poly(3,4-ethylenedioxythiophene)...
