The progress of nanomaterials for carbon dioxide capture via the adsorption process

Abstract

As a major component of greenhouse gases (GHGs), excessive CO2 emissions have led to a series of environmental issues. Therefore, CO2 capture and storage (CCS) have attracted extensive attention from both fundamental and practical research communities. However, traditional adsorbents and catalysts still have many defects in CO2 capture and transformation. In recent years, nanomaterials have been considered as promising adsorbents for CO2 capture due to their high adsorption capacity, low cost and wide availability. This review article describes the main technologies used for CO2 capture, highlights the latest research status of nanomaterials for CO2 capture, and investigates the influence of surface microstructure and modification of materials on CO2 capture ability. Although many new nanomaterials and capture technologies have been developed, the high cost and the low technology scale of CO2 capture remain major obstacles. Future research should focus on designing low-cost, high-availability nanomaterials to reduce CO2 emission from large-scale power plants.
