A new type of imidazolium salt-modified porous hypercrosslinked polymer (BET surface area up to 926 m(2) g(-1)) was reported. These porous materials exhibited good CO2 capture capacities (14.5 wt%) and catalytic activities for the conversion of CO2 into various cyclic carbonates under metal-free conditions. The synergistic effect of CO2 capture and conversion was observed.

This report presents the synthesis of a tetraphenyladamantane-based microporous polycyanurate network with a BET surface area of 843 m(2) g(-1) and a pore size of 7.8 Å. It uptakes 98.0 wt% benzene (298 K, P/P0 = 0.9), 1.49 wt% H2 (77 K/1 bar) and 12.8 wt% CO2 (273 K/1 bar) with CO2/N2 selectivity of up to 112.

Undoped TiO(2) and TiO(2) nanoparticles doped with 1-5 at.% Nb were successfully produced in a single step by flame spray pyrolysis (FSP). The phase and crystallite size were analyzed by XRD. The BET surface area (SSA(BET)) of the nanoparticles was measured by nitrogen adsorption. The trend of SSA(BET) on the doping samples increased and the BET equivalent particle diameter (d(BET)) (rutile) in...

A facile sulfur-bubble template-mediated synthesis of uniform porous g-C3N4 has been developed for the first time. The obtained sulfur-mediated g-C3N4 presents a uniform porous structure with higher BET surface area and displays superior photocatalytic performance compared with pure g-C3N4.

Pt/fluorinated clay nanocomposites were prepared by clay-mediated in situ reduction; these nanocomposites demonstrated ultrahigh Pt nanoparticle thermal stability (up to 1000 °C), large BET surface area (379 m(2) g(-1)), uniform dispersion in aqueous media, and intriguing catalytic properties.

Nanostructured silicon hollow spheres with a thin shell have been synthesized by magnesium reduction of silica spheres, which possess a high BET surface area and are electrochemically active in capacitive energy storage with a maximum specific capacitance of 193 F g(-1) in the neutral Na(2)SO(4) aqueous solution.

1,3,5-Tris(4-carboxyphenyl)benzene assembles into an intricate 8-fold polycatenated assembly of (6,3) hexagonal nets formed through hydrogen bonds and π-stacking. One polymorph features 56 independent molecules in the asymmetric unit, the largest Z' reported to date. The framework is permanently porous, with a BET surface area of 1095 m(2) g(-1) and readily adsorbs N2, H2 and CO2.

Greatly enhanced microporosity is obtained for the amorphous porous polymers produced from the AlCl3-mediated coupling of aromatic hydrocarbons by using dichloromethane as the reaction solvent. A polymer of average BET surface area 1⁄4 2435 m g 1 was obtained reproducibly from 1,3,5-triphenylbenzene with the additional porosity being provided as ultramicroporosity as demonstrated by very high C...

Mesoporous g-C3N4 has been obtained by a facile sucrose-mediated approach via thermal condensation of sucrose and melamine for the first time. The mesoporous g-C3N4 presents a much higher BET surface area and displays highly enhanced photocatalytic H2 evolution performance.

Low-cost and environmentally-friendly materials are investigated as carbon-coating precursors to modify the surface of commercial graphite for Li-ion battery anodes. The coating procedure and final carbon content are tuned to study the influence of the precursors on the electrochemical performance of graphite. Thermogravimetric analysis (TGA) and Brunauer– Emmett–Teller (BET) surface area analy...
