Application of a solid electrolyte CO2 sensor to the performance evaluation of CO2 capture materials

Integrated near-infrared QEPAS sensor based on a 28 kHz quartz tuning fork for online monitoring of CO2 in the greenhouse

“…These electrochemical CO 2 sensors have poor gas selectivity and short service life [10] . The solid electrolyte CO 2 sensor has attracted the attention of researchers because of its good sensitivity and the characteristics of being less affected by temperature [11] , [12] , [13] . The CO 2 sensors mentioned above have the shortcomings of relatively poor detection sensitivity, susceptibility to environmental noise, and slow response time, compared with the laser sensing technologies.…”

Graphene-based nanomaterials for CO2 capture and conversion

“…These computational studies have paved the way toward fundamental understanding and insights of the chemistry between graphene-based adsorbents and CO 2 (and other gas mixtures), which are beneficial for the selection and synthesis of novel adsorbents (Chowdhury & Balasubramanian, 2016a,b,c;Chowdhury et al, 2015;Kudahi et al, 2017;Li et al, 2016;Liu et al, 2021;Ning et al, 2021;Stanly et al, 2019) (Table 8.3). To date, graphene-based materials have been hailed to have an immense potential for large range of industrial applications including semiconductors, optoelectronics, CO 2 capture, hydrogen (H 2 ) storage, catalysts, and sensors to name a few (Bardi et al, 2020;Loy et al, 2019;Stoller et al, 2008;Yamamoto et al, 2020). On this ground, large interests have been dedicated to photocatalytic activities owing to their unique characteristics such as large surface area, high adsorption capacity, high stability, and flexible tuning physiochemical characteristics, as well as high carrier mobility (Bonaccorso et al, 2015;Purkait et al, 2017;Szcze ˛śniak et al, 2017).…”

Transition Metal Dichalcogenides for the Application of Pollution Reduction: A Review

“…Valorization of carbon dioxide (CO 2 ) to raw chemical materials and clean fuels is an opportunity for the artificial carbon cycle, which contributes to the mitigation of global warming and alleviates the usage of fossil [232]. Over the decades, enormous efforts in searching of alternative technologies to mitigate the CO 2 emissions through CO 2 capture from concentrated industrial exhausts [233,234], sequestration of CO 2 in the underground [235,236] and conversion of CO 2 to energy-rich fuels powered by renewable energy resources [237] have been discovered. Throughout all these methods, CO 2 molecules are not solely can be removed from the atmosphere but also can be converted into value-added chemicals such as methanol, formic acid, methane, and syngas [238][239][240].…”
