“…Unlike two-step procedure, in one-step procedure, the temperature is ramped up from room temperature to the required activation temperature, and both carbonization and activation steps are carried out simultaneously in the presence of oxidizing agents. One-step activation is preferable because of the reduced production costs in terms of time and energy [24]. For example, Yang et al reported that activated carbon with high BET surface area of 1667 m 2 g −1 can be directly prepared from coconut shell by one-step CO 2 activation at 900 °C for 140 min [25]; Gonçalves et al found that compared with two-step CO 2 activation, one-step activation resulted in a higher BET surface area of the activated carbon using bagasse/molasses pellet as the raw material [26].…”

Porous carbons (PCs) were prepared from seawater (SW)-impregnated sawdust (SD) by CO 2 activation at 700 °C. The preparation process was investigated on-line by thermogravimetric analyzer coupled with FTIR (TG-FTIR). PCs were characterized by N 2-adsorption/desorption and Fourier transform infrared spectroscopy. The adsorption abilities of PCs for oxytetracycline (OTC) were compared and the adsorption isotherms of OTC on the optimum sample were studied. Results showed that SW impregnation led to the release of more CO from SD at 700 °C, indicating a higher degree of CO 2 activation, thus a 81% higher BET surface area (S BET) can be achieved under the same activation condition. Mesopore volume of PC increased from 0.089 to 0.301 cm 3 g −1 with the activation time increasing from 5 to 60 min. PC obtained after 60-min activation with a S BET of 490 m 2 g −1 and an average pore diameter of 3.78 nm had the highest adsorption ability for OTC. Its adsorption equilibrium data for OTC followed Langmuir model with a maximum monolayer adsorption capacity up to 100 mg g −1 .

“…Theoretically, both the hydroxy group and amino group have a favorable interaction via hydrogen bonding with the poly(ethylene oxide) (PEO) moiety of F127, which can induce an ordered assembly between reactant and F127 [43] . For instance, Hao et al [44] .…”

The atmospheric CO2 concentration continues a rapid increase to its current record high value of 416 ppm for the time being. It calls for advanced CO2 capture technologies. One of the attractive technologies is physical adsorption‐based separation, which shows easy regeneration and high cycle stability, and thus reduced energy penalties and cost. The extensive research on this topic is evidenced by the growing body of scientific and technical literature. The progress spans from the innovation of novel porous adsorbents to practical separation practices. Major CO2 capture materials include the most widely used industrially relevant porous carbons, zeolites, activated alumina, mesoporous silica, and the newly emerging metal‐organic frameworks (MOFs) and covalent‐organic framework (COFs). The key intrinsic properties such as pore structure, surface chemistry, preferable adsorption sites, and other structural features that would affect CO2 capture capacity, selectivity, and recyclability are first discussed. The industrial relevant variables such as particle size of adsorbents, the mechanical strength, adsorption heat management, and other technological advances are equally important, even more crucial when scaling up from bench and pilot‐scale to demonstration and commercial scale. Therefore, we aim to bring a full picture of the adsorption‐based CO2 separation technologies, from adsorbent design, intrinsic property evaluation to performance assessment not only under ideal equilibrium conditions but also in realistic pressure swing adsorption processes.

It is desirable for a sustainable society that the production and utilization of renewable materials are net‐zero in terms of carbon emissions. Carbon materials with emerging applications in CO2 utilization, renewable energy storage and conversion, and biomedicine have attracted much attention both academically and industrially. However, the preparation process of some new carbon materials suffers from energy consumption and environmental pollution issues. Therefore, the development of low‐cost, scalable, industrially and economically attractive, sustainable carbon material preparation methods are required. In this regard, the use of biomass and its derivatives as a precursor of carbon materials is a major feature of sustainability. Recent advances in the synthetic strategy of sustainable carbon materials and their emerging applications are summarized in this short review. Emphasis is made on the discussion of the original intentions and various sustainable strategies for producing sustainable carbon materials. This review provides basic insights and significant guidelines for the further design of sustainable carbon materials and their emerging applications in catalysis and the biomedical field.
