Imine-Linked Polymer Based Nitrogen-Doped Porous Activated Carbon for Efficient and Selective CO2 Capture
The preparation of nitrogen-doped activated carbon (NACs) has received significant attention because of their applications in CO2 capture and sequestration (CCS) owing to abundant nitrogen atoms on their surface and controllable pore structures by carefully controlled carbonization. We report high-surface-area porous N-doped activated carbons (NAC) by using soft-template-assisted self-assembly ...
متن کاملSynthesis of nitrogen-doped hollow carbon nanospheres for CO2 capture.
Here, we report the synthesis of nitrogen-doped hollow carbon nanospheres (N-HCSs) via a two-step Stöber method. The resultant N-HCSs possess a uniform size of ∼220 nm, a high nitrogen loading content of 14.8 wt% and a high surface area of 767 m(2) g(-1), as well as exhibit a considerable performance for CO2 capture with a capacity of 2.67 mmol g(-1) and a high selectivity in a mixture gas (N2 ...
متن کاملA one-step carbonization route towards nitrogen-doped porous carbon hollow spheres with ultrahigh nitrogen content for CO2 adsorption.
Nitrogen doped porous carbon hollow spheres (N-PCHSs) with an ultrahigh nitrogen content of 15.9 wt% and a high surface area of 775 m(2) g(-1) were prepared using Melamine-formaldehyde nanospheres as hard templates and nitrogen sources. The N-PCHSs were completely characterized and were found to exhibit considerable CO2 adsorption performance (4.42 mmol g(-1)).
متن کاملDesign and Synthesis of Nitrogen-Doped Porous Carbon Materials for CO2 Capture and Investigation of CO2 Sorption Kinetics
Solid-state post-combustion CO2 sorbents have certain advantages over traditional aqueous amine systems, including reduced regeneration energy since vaporization of liquid water is avoided, tunable pore morphology, and greater chemical variability. This report includes two parts, i.e., the design and synthesis of nitrogen-doped porous carbons as CO2 sorbents and the development of a robust tech...
متن کاملNitrogen-doped porous carbon materials generated via conjugated microporous polymer precursors for CO2 capture and energy storage
Heteroatom doping and well-tuned porosity are regarded as two important factors of porous carbon materials (PCMs) for various applications. However, it is still difficult to tune a single variable while retaining the other factors unchanged, which restricts rational and systematic research on PCMs. In this work, in situ nitrogen-doped porous carbon material (NPCM-1) and its non-doped analogue P...
