Efficient Fixation of Carbon Dioxide by Hypervalent Organobismuth Oxide, Hydroxide, and Alkoxide

Abstract

Keeping the lid on CO2: Atmospheric CO2 can be trapped irreversibly by hypervalent organobismuth oxide and hydroxide compounds, while an analogous alkoxide binds this greenhouse gas reversibly (see scheme). The hypervalent nature of the bismuth compounds is shown to play a decisive roll in these reactions.

Graphene-manganese oxide hybrid porous material and its application in carbon dioxide adsorption

“…Mn 3 O 4 shows the lowest carbon dioxide adsorption capacity, and the value of HTG is about 7.7 wt% which is comparable to the carbon material previously reported [1, 3,4]. The carbon dioxide adsorption capacities of the GMNO samples show a maximum value of about 11.4 wt% at GMNO-4, which is larger than HTG and Mn 3 O 4 .…”

“…In the purpose of sustainability, scientists are devoting to find ways to control the carbon dioxide emission and separate/adsorb the greenhouse gas. For the latter one, there are four main approaches: cryogenic distillation, membrane purification, absorption with liquids [2], and adsorption using solids [3,4]. Using solid adsorbent is widely considered, such as zeolites [5,6], activated carbons [7,8], metal oxides [9,10], and supported amines [11].…”

3-(2-Hydroxyl-Ethyl)-1-Propylimidazolium Bromide Immobilized on SBA-15 as Efficient Catalyst for the Synthesis of Cyclic Carbonates via the Coupling of Carbon Dioxide with Epoxides

“…However, their catalytic activities were not satisfactory. We have made a series of attempts to develop high-efficiency catalysts and absorbents for CO 2 utilization [2,[48][49][50]. As an extension of our researches, we immobilized a HIL, viz.…”

Computational Chemistry Study of CO2Fixation and Cyclic Carbonate Synthesis Using Various Catalysts

“…이 반응은 단점이 있는데 높은 활성화 에너지(activation energy)를 가지기 때문에(55~59 kcal/mol) 높 은 발열(exothermic)에도 불구하고 비촉매 상태에서는 자발적 으로 반응이 일어나지 않는다는 것이다 [7]. 그로 인해 지난 수 십 년간 포스핀 [8][9][10], 유기염기 [11], 이온성 액체 [12][13][14][15][16][17], 유 기금속착물 [18][19][20][21], 금속산화물 [22][23][24], 담지된 촉매 [25][26][27] [28], 암모늄염(ammonium salt) [29], 금 속 할로겐염(metal halide salt) [30], 알카놀아민(alkanolamine) [31]. 본 논문에서는 본 연구팀에 의해 타 문헌에 제시된 반응 메커니즘들을 새로이 에너지도(energetics)로 통합하여 정리 …”
