Synthesis and Characteristics of Double-Shell Mesoporous Hollow Silica Nanomaterials to Improve CO<sub>2</sub> Adsorption Performance

To improve the adsorption performance of carbon dioxide, which is considered the main culprit of greenhouse gases, the specific surface area and high pore volume of the adsorbing material should be considered. For a porous material, the performance of carbon dioxide adsorption is determined by the a...
