A hierarchically porous phenolic resin-type polymer has been successfully prepared by a solvothermal reaction. Given the relatively high surface area, hierarchical pores, good stability and abundant -OH reactive groups, this polymer exhibits high CO2 adsorption and efficient catalytic conversion for CO2 cycloaddition.

In this work we reported the carbon dioxide adsorption (CO2) in six different nanostructures in order to investigate the capturing capacity of the materials at nanoscale. Here we have considered the three different nanotubes including zinc oxide nanotube (ZnONT), silicon carbide nanotube (SiCNT) and single walled carbon nanotube (SWCNT). Three different chiralities such as zigzag (9,0), armchai...

Herein we report the electrocatalytic activity of boron-doped graphene for the reduction of CO2. Electrolysis takes place at low overpotentials leading exclusively to formate as the product (vis-à-vis benchmark Bi catalyst). Computational studies reveal mechanistic details of CO2 adsorption and subsequent conversion to formic acid/formate.

A new NbO-type metal-organic framework ZJNU-40 incorporating highly polarized benzothiadiazole moieties exhibits a high CO2 uptake of 108 cm(3) g(-1) at 296 K and 1 atm, as well as good adsorption selectivities of CO2 over CH4 and N2 at room temperature, which is superior to that of the analogous MOF NOTT-101.

An unprecedented layered Pb-Kemp's triacid compound, Pb3[C6(CH3)3(CO2)3H6]2[DMF]3, has been synthesized. The material exhibits a selective CO2 adsorption, a reversible DMF coordination, and an intercalative hexanal addition reaction. A competing crystallization reaction under solvothermal conditions using Pb(2+) and Cd(2+) with Kemp's triacid reveals higher selectivity of Cd(2+) over Pb(2+).

Highly porous nitrogen-doped activated carbons (NACs) were prepared by the chemical activation of chitosan using alkali carbonates. The NACs exhibited extremely high CO2 capacities of 1.6 mmol g(-1) (15 kPa) and 4.9 mmol g(-1) (100 kPa) at 25 °C. Nitrogen atoms doped into carbon frameworks clearly enhanced CO2 adsorption at low partial pressures.

CO2 uptake in zirconium MOF UiO-66 almost doubles with post-synthetic exchange of Zr by Ti. This was due to smaller pore size and higher adsorption enthalpy, with good complementarity between experiment and simulation. Furthermore, the full effect is obtained with ~50% Ti loading, precluding the need to fully substitute frameworks for CO2 capture.

SAPO-56 crystals were synthesized via microwave heating. The resultant crystals displayed high catalytic activity in the synthesis of chloropropene carbonate from CO2 and epichlorohydrin. The enhanced catalytic activity of SAPO-56 crystals was related to their high CO2 adsorption capacity, small crystal size, and the presence of acid sites.

Using quantum chemical methods, we have screened a variety of functional groups for their ability to bind CO2 and water. Most functional groups bind water more strongly than CO2, making them ineffective for incorporation into materials for removing CO2 from humid flue gas. Preliminary calculations suggest that adding perfluorinated functional groups strongly suppresses water binding, while havi...
