Carbon Capture From Flue Gas and the Atmosphere: A Perspective

Frontiers in Energy Research, Год журнала: 2020, Номер 8

Опубликована: Дек. 15, 2020

Climate change has become a worldwide concern with the rapid rise of atmospheric Co2 concentration. To mitigate emissions, research and development efforts in capture separation both from stationary sources high concentrations (e.g., coal-fired power plant flue gas) directly atmosphere have grown significantly. Much progress been achieved, especially within last twenty years. In this perspective, we first briefly review current status carbon technologies including absorption, adsorption, membrane, biological capture, cryogenic separation, compare their advantages disadvantages. Then, focus mainly on recent advances membrane technologies. Even though numerous optimizations materials processes pursued, implementing single process is still quite energy-intensive or costly. address challenges, provide our perspectives future directions development, that is, combination gas recycling hybrid system, one-step integrated conversion as they potential to overcome technical bottlenecks technologies, offering significant improvement energy efficiency cost-effectiveness.

Biomass waste-derived porous carbons (BWDPCs) are a class of complex materials that widely used in sustainable waste management and carbon capture. However, their diverse textural properties, the presence various functional groups, varied temperatures pressures to which they subjected during CO2 adsorption make it challenging understand underlying mechanism adsorption. Here, we compiled data set including 527 points collected from peer-reviewed publications applied machine learning systematically map as function compositional properties BWDPCs parameters. Various tree-based models were devised, where gradient boosting decision trees (GBDTs) had best predictive performance with R2 0.98 0.84 on training test data, respectively. Further, classified into regular (RPCs) heteroatom-doped (HDPCs), again GBDT model 0.99 0.86 0.79 for RPCs HDPCs, Feature importance revealed significance parameters, order precedence BWDPC-based adsorption, effectively guiding synthesis applications.

Опубликована: Март 17, 2022

Abstract Direct photocatalytic CO 2 reduction from primary sources, such as flue gas and air, into fuels, is highly desired, but the thermodynamically favored O almost completely impedes this process. Herein, we report on efficacy of a composite photocatalyst prepared by hyper-crosslinking porphyrin-based polymers hollow TiO surface subsequent coordinating with Pd(II). Such exhibits high resistance against inhibition, leading to 12% conversion yield air after 2-h UV-visible light irradiation. In contrast, over Pd/TiO without polymer severely inhibited presence ( ≥ 0.2 %). This study presents feasible strategy, building Pd(II) sites -adsorptive surface, for realizing H in an aerobic environment /O adsorption selectivity efficient charge separation oxidation , respectively.

ConspectusThe continuing increase of the concentration atmospheric CO2 has caused many environmental issues including climate change. Catalytic conversion using thermochemical, electrochemical, and photochemical methods is a potential technique to decrease simultaneously obtain value-added chemicals. Due high energy barrier however, this method still far from large-scale applications which requires activity, selectivity, stability. Therefore, development efficient catalysts convert different products urgent. With their well-engineered pores chemical compositions, surface area, elevated adsorption capability, adjustable active sites, porous crystalline frameworks metal-organic (MOFs) covalent organic (COFs) are materials for catalytic conversion. Here, we summarize our recent work on MOFs COFs thermocatalytic, electrocatalytic, photocatalytic describe structure-activity relationships that could guide design effective catalysts.The first section paper describes imidazolium-functionalized MOFs, liquid cationic with nucleophilic halogen ions, can promote thermocatalytically cycloaddition reaction epoxides toward cyclic carbonates at one bar pressure. A MOF takes role reservoir tackle low local concentrations in gas-liquid-solid heterogeneous reactions. Imidazolium-functionalized ions avoid use cocatalysts, leads milder more facile experimental conditions separation processes.In dealing electrocatalytic reduction (CO2RR), developed series conductive framework fast electron transmission capabilities, afford current densities outperform traditional COF have been reported. The intrinsically two-dimensional 2D nanosheets based fully π-conjugated phthalocyanine motif excellent transport capability were prepared, strong transporters also integrated into metalloporphyrin-based CO2RR. Cu2O quantum dots Cu nanoparticles (NPs) be uniformly dispersed MOFs/COFs synergistic and/or tandem electrocatalysts, achieve highly selective production CH4 or C2H4 CO2RR.A third efforts facilitate electron-hole photocatalysis.
