Abstract The important role of mesopores has been investigated in electric double-layer capacitors (EDLCs) operating from 24 °C down to − 40 by using two in-house synthesized carbons with hierarchical porosity. These were prepared colloidal nanoparticles SiO 2 as the template and d -glucose carbon source. A decrease average diameter 12 8 nm results increased surface area offers a perfect match ...

Abstract In this study, the effect of mesopores in Marimo nanocarbon (MNC) anode material on power generation performance a direct glucose fuel cell was investigated. Three types MNC with different mesopore distributions were used for catalyst support material; Pt as loaded metal. test, containing many pores approximately 35 nm showed highest maximum output density 0.72 mW cm−2 at 5 wt% metal l...

A new photocatalyst for CO2 reduction has been presented. The was prepared from a combination of commercial P25 with mesopore structure and carbon spheres microporous high adsorption capacity. Then, the obtained hybrid TiO2-carbon sphere photocatalysts were deposited on glass fiber fabric. combined spheres/silica cloth showed higher efficiency in two-electron towards CO than eight-electron reac...

Abstract Fractal dimension can be used to the pore surface characterize. For structures in different sizes, calculation models of fractal theory should distinguished due principles gas adsorption experiments. To further study adaptability model for experimental data, author collected shale samples Longmaxi formation from Well JY1, then CO 2 and N provided PSD curves. In addition, dimensions mic...
