Yeast‐Based Microporous Carbon Materials for Carbon Dioxide Capture

Abstract

A hierarchical microporous carbon material with a Brunauer–Emmett–Teller surface area of 1348 m2 g−1 and a pore volume of 0.67 cm3 g−1 was prepared from yeast through chemical activation with potassium hydroxide. This type of material contains large numbers of nitrogen‐containing groups (nitrogen content >5.3 wt %), and, consequently, basic sites. As a result, this material shows a faster adsorption rate and a higher adsorption capacity of CO2 than the material obtained by directly carbonizing yeast under the same conditions. The difference is more pronounced in the presence of N2 or H2O, showing that chemical activation of discarded yeast with potassium hydroxide could afford high‐performance microporous carbon materials for the capture of CO2.

Breakthrough adsorption studies of mixed gases on mango (Mangifera indicaL.) seed shell derived activated carbon extrudes

“…For the 54 development of activated carbon umpteen numbers of sources are 55 available, e.g. industrial wastes [18], synthetic chemicals [19], 56 plastics [20] and carbides [21]. High quality of carbon cannot be 57 achieved simply by tailoring the synthetic protocols and post 58 modification, sources of carbon also contributes significantly due 59 to their inbuilt characters/quality.…”

Superior carbon-based CO2 adsorbents prepared from poplar anthers

“…The precursors used for preparation of porous carbons include petroleum pitch [13,14], organic polymer [15][16][17], biomass [18][19][20][21] and coal [22][23][24]. From the viewpoint of green and sustainable chemistry, the waste biomass such as sawdust, yeast [25], animal bone, hemp stem [26] and bean dreg is more attractive. In particular, the textural and chemical properties of the obtained porous carbons are easily facilitated by changing preparation conditions [27][28][29] and raw materials, and thus, giving the materials interesting adsorptive, electrochemical and catalytic properties [30,31].…”
