“…Biochar, as a byproduct from thermal pyrolysis of biomass under an oxygen-deficient environment, could be a promising substitute for activated carbon due to its source abundance, low cost, and renewability. − In this regard, CuO is combined with biochar to construct CuO/biochar composites. Moreover, ZrO 2 addition could essentially improve the high-temperature durability of metal oxides, thus, Tang et al developed a ZrO 2 -doped CuO/biochar catalyst for mercury removal, which showed a good Hg 0 removal activity within 60–270 °C.…”

Mercury emission has become a global concern due to the potential risks Hg poses to human health and the environment. Currently, copper-based compounds, such as CuCl 2 , CuO, CuS, and CuSe, have attracted great attention in mercury emission control, because of their low cost and decent removal efficiency. This review provides an overview of the recent progress on adsorptive and catalytic oxidation removal of elemental mercury over copper-based composites. Supported CuCl 2 can majorly serve as an inexpensive and efficient catalyst toward Hg 0 oxidation. Nevertheless, the high volatility and water solubility of mercury chloride may cause halogen release and a potential leaching risk of mercury, respectively. Due to its superior redox property, CuO is fairly active in Hg 0 oxidation. Metal incorporation can distinctly strengthen the mercury removal performance. However, CuO-based composites can be easily poisoned or suppressed by flue gas constituents owing to the generation of inactive copper sulfates/nitrates or competitive adsorption. CuS-based composites appear to be the most promising sorbents for mercury capture, because of strong Hg 0 affinities and remarkable tolerances to steam and sulfur dioxide. CuSe-based composites show mercury capture performances similar to those of CuS-based composites. However, tedious synthetic processes and expensive Se precursors hinder their industrial implementation.

“…Depending on the arrangement of the carbon atoms, carbon-based materials have different morphologies. In particular, CBMs have significantly contributed toward photocatalysis because of their high surface area, outstanding conductivity, excellent chemical stability, and remarkable mechanical strength, as well as their environmental friendliness and widespread availability [ 18 ]. Considering the importance of carbon materials, their precursors must be inexpensive and effective, as well as natural and recyclable.…”

Carbon-based nanomaterials (CBM) have shown great potential for various environmental applications because of their physical and chemical properties. The unique hybridization properties of CBMs allow for the tailored manipulation of their structures and morphologies. However, owing to poor solar light absorption, and the rapid recombination of photogenerated electron-hole pairs, pristine carbon materials typically have unsatisfactory photocatalytic performances and practical applications. The main challenge in this field is the design of economical, environmentally friendly, and effective photocatalysts. Combining carbonaceous materials with carbonaceous semiconductors of different structures results in unique properties in carbon-based catalysts, which offers a promising approach to achieving efficient application. Here, we review the contribution of CBMs with different dimensions, to the catalytic removal of organic pollutants from wastewater by catalyzing the Fenton reaction and photocatalytic processes. This review, therefore, aims to provide an appropriate direction for empowering improvements in ongoing research work, which will boost future applications and contribute to overcoming the existing limitations in this field.

“…In recent years, the applications of CCUS technology have been restricted because of the high cost of the process of carbon capture, among which the capture efficiency and performance of captured materials are key factors affecting the cost of CO 2 capture. , Therefore, the development of carbon capture materials with high efficiency and high performance is the biggest challenge faced by CCUS technology. , A variety of solid adsorbents, including zeolite, , metal–organic framework (MOF), , silica material, , and carbonaceous material − can be used for CO 2 capture; however, porous carbon with advantages of relatively low renewable energy, high specific surface area, chemical stability, cost effectiveness, and manufacturing maturity has been widely studied . Yet different modification techniques, like material activation or element doping, can enhance the functionality of porous carbon materials and produce a superior CO 2 capture effect. , Selecting adsorbents with considerable CO 2 adsorption capacity, rapid adsorption kinetics, and forceful selectivity and stability of CO 2 and N 2 for experiment and simulation are the key to improving CO 2 capture . With these advantages in mind, many researchers − have been involved in the modification of novel solid adsorbents in order to enhance the adsorbents’ adsorption capacity and the ideal economical cost of CO 2 separation.…”

CO 2 capture technology is a crucial method to achieve global carbon emission reduction, and the benefits of the physical adsorption method in the post-combustion CO 2 capture technology are low energy usage and running costs. Nitrogendoped porous carbon is selected as a solid adsorbent due to its high specific surface area and excellent adsorption selectivity. This study uses nitrogen-doped porous carbon prepared in experiment to determine its main properties, and the adsorption equilibrium isotherm is fitted. The adsorption bed model is established using ANSYS Fluent to simulate the heat and mass transfer of the adsorption process and fluid flow and is verified by the published experimental data. Temperature swing adsorption (TSA) is divided into three stages: adsorption, desorption, and cooling. The effects of different inlet velocities and porosities on adsorption and desorption performance are studied. The results reveal that the mesh verification and experimental verification are in good agreement with the results so that the numerical model can be used for species transport processes of various sizes, geometric shapes, and other mixed gases. It is essential to mention that this adsorption cycle process can recover excellent purity and decent recovery and productivity of product gases, which is of great significance for the practical application and industrialization of carbon capture technology.
