The Prospects of Clay Minerals from the Baltic States for Industrial-Scale Carbon Capture: A Review

Abstract

Carbon capture is among the most sustainable strategies to limit carbon dioxide emissions, which account for a large share of human impact on climate change and ecosystem destruction. This growing threat calls for novel solutions to reduce emissions on an industrial level. Carbon capture by amorphous solids is among the most reasonable options as it requires less energy when compared to other techniques and has comparatively lower development and maintenance costs. In this respect, the method of carbon dioxide adsorption by solids can be used in the long-term and on an industrial scale. Furthermore, certain sorbents are reusable, which makes their use for carbon capture economically justified and acquisition of natural resources full and sustainable. Clay minerals, which are a universally available and versatile material, are amidst such sorbents. These materials are capable of interlayer and surface adsorption of carbon dioxide. In addition, their modification allows to improve carbon dioxide adsorption capabilities even more. The aim of the review is to discuss the prospective of the most widely available clay minerals in the Baltic States for large-scale carbon dioxide emission reduction and to suggest suitable approaches for clay modification to improve carbon dioxide adsorption capacity.

Effects of Surface Hydrophilicity and Heterogeneity on CO2 Conversion to H2CO3 in the Nanopores of Layered Materials

“…Carbon dioxide (CO 2 ) interaction with water in material nanopores play an important role in carbon dioxide removal and sequestration. , For example, in geological sequestration, numerous investigations concluded that clay adsorbs a significant amount of CO 2 into clay interlayers. , In CO 2 removal via enhanced weathering, CO 2 forms carbonic acid that dissolves rock (e.g., basalt) and releases Ca 2+ and Mg 2+ . Geological minerals are also potential alternatives to more complex materials that often require significant chemical functionalization to ensure acceptable carbon capture performance. , Geological minerals have the distinct advantages of large surface area, high porosity, abundant basic sites, excellent thermal and chemical stability, and low cost .…”

Metal–Organic Frameworks (MOFs) Containing Adsorbents for Carbon Capture

“…In addition, their modification allows for the improvement of CO 2 adsorption capabilities even more. The prospects of the most widely available clay minerals in the Baltic States for large-scale CO 2 emission reduction and suitable alternative approaches for clay modification to improve CO 2 adsorption capacity can be found in review [66]. Recently, clay-containing MOF-composites have been studied for various purposes.…”
