“…Tailings, as another culprit of ecological destruction, have been piled up, disposed, and utilized inadequately for decades, causing irreversible serious damage to the environment. How to efficiently transform and utilize tailings and other solid waste resources has become a global environmental and resource problem that needs to be solved urgently. − Therefore, if we can provide an approach for CO 2 emission reduction while realizing the high-value utilization of tailings and maximize the resource utilization of resources by using waste to treat waste, we will make sustainable contributions to environmental protection and energy conservation.…”

In this work, a Ni-based catalyst supported on a core–shell structure catalytic carrier material (Ni/ZSM-5@MCM-41) based on kaolinite tailings is reported, which exhibits excellent CO2 methanation performance at atmospheric pressure. At 400 °C, CO2 conversion and CH4 selectivity reach 80 and 97% with the space velocity of 12,000 mL gcat –1 h–1, respectively, and it can maintain good stability during the 80 h stability test. Compared with traditional Ni/ZSM-5 and Ni/MCM-41 catalysts, Ni/ZSM-5@MCM-41 has more substantial confinement effects on the active components, and the active components are more evenly dispersed on surface of the carrier. In addition, it is confirmed by the in situ diffuse reflectance infrared Fourier transform spectroscopy technique that CO2 methanation over the Ni/ZSM-5@MCM-41 catalyst follows the path of formate and CO as intermediates.

In this work, the synthesis of ordered mesoporous silica of MCM-41 type was investigated aimed at improving its morphology by varying the synthesis conditions in a one-pot process, employing different temperatures and solvent conditions. 2-methoxyethanol was used as co-solvent to ethanol. The co-solvent ratio and the synthesis temperature were varied. The pore morphology of the materials was characterized by nitrogen porosimetry and small angle neutron scattering (SANS), and the particle morphology by transmission electron microscopy (TEM) and ultra-small angle neutron scattering (USANS). The thermal behavior was investigated by simultaneous thermogravimetry-differential scanning calorimetry (TG-DSC) measurements. The SANS and N2 sorption results demonstrated that a well-ordered mesoporous structure was obtained at all conditions in the synthesis at room temperature. Addition of methoxyethanol led to an increase of the pore wall thickness. Simultaneously, an increase of methoxyethanol content led to lowering of the mean particle size from 300 to 230 nm, according to the ultra-small angle scattering data. The ordered porosity and high specific surfaces make these materials suitable for applications such as adsorbents in environmental remediation. Batch adsorption measurements of metal ion removal from aqueous solutions of Cu(II) and Pb(II) showed that the materials exhibit dominantly monolayer surface adsorption characteristics. The adsorption capacities were 9.7 mg/g for Cu(II) and 18.8 mg/g for Pb(II) at pH 5, making these materials competitive in performance to various composite materials.
