Abstract

Anthropogenic CO2 emission makes significant contribution to global climate change and CO2 capture and storage is a currently a preferred technology to change the trajectory toward irreversible global warming. In this work, we reported a new strategy that the inexhaustible MgCl2 in seawater and the abundantly available biomass waste can be utilized to prepare mesoporous carbon stabilized MgO nanoparticles (mPC-MgO) for CO2 capture. The mPC-MgO showed excellent performance in the CO2 capture process with the maximum capacity of 5.45 mol kg(-1), much higher than many other MgO based CO2 trappers. The CO2 capture capacity of the mPC-MgO material kept almost unchanged in 19-run cyclic reuse, and can be regenerated at low temperature. The mechanism for the CO2 capture by the mPC-MgO was investigated by FTIR and XPS, and the results indicated that the high CO2 capture capacity and the favorable selectivity of the as-prepared materials were mainly attributed to their special structure (i.e., surface area, functional groups, and the MgO NPs). This work would open up a new pathway to slow down global warming as well as resolve the pollution of waste biomass.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • CO2 reacts with MgO on the biochar surface to form MgCO3, and interacts with surface hydroxyl via hydrogen bonding apart from physical adsorption.

    “This is due to the fact that ­ CO 2 also reacts with MgO on the biochar surface to form ­ MgCO 3 , and interacts with surface hydroxyl via hydrogen bonding apart from physical adsorption (Liu et al. 2013).”

  • MgO-modified biochar has a high CO2 adsorption capacity of 5.45 mmol/g.

    “For instance, Liu et al. (2013) fabricated MgO-modified biochar with a high adsorption capacity of 5.45 mmol/g.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
