Article Abstract
In this work, the MCM-48 mesoporous material was prepared and characterized to apply it as an active adsorbent for the adsorption of 4-nitroaniline (4-Nitrobenzenamine) from wastewater. The MCM-48 characterizations were specified by implementing various techniques such as; scanning electron microscopy (SEM), Energy dispersive X-ray analysis (EDAX), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) surface area, pore size distribution (PSD), and Fourier transform infrared (FTIR). The batch adsorption results showed that the MCM-48 was very active for the 4-nitroaniline adsorption from wastewater. The adsorption equilibrium results were analyzed by applying isotherms like Langmuir, Freundlich, and Temkin. The maximum experimental uptake according to type I Langmuir adsorption was found to be 90 mg g approximately. The Langmuir model with determination coefficient R = 0.9965 is superior than the Freundlich model R = 0.99628 and Temkin model R = 0.9834. The kinetic adsorption was investigated according to pseudo 1st order, pseudo 2nd order, and Intraparticle diffusion model. The kinetic results demonstrated that the regression coefficients are so high R = 0.9949, that mean the pseudo 2nd order hypothesis for the adsorption mechanism process appears to be well-supported. The findings of adsorption isotherms and kinetics studies indicate the adsorption mechanism is a chemisorption and physical adsorption process.

The detrimental effects of heavy metal aqueous pollution are attracting people's attention increasingly. Membrane separation technology plays a pivotal role in the treatment of aqueous pollution due to its low energy consumption and excellent separation effect. Inspired by the strong adhesion of heavy metal ions by the dopamine in mussel protein, we have fabricated the 5%, 10%, 20% and 30% proportion of polydopamine (PDA)/Polymethyl methacrylate (PMMA) blend membranes with dopamine structure by solvent-induced phase conversion.

Electrochemical carbon dioxide reduction reaction (CO2RR) to highly value-added C2+ fuels or chemicals is a promising pathway to address environment issues and energy crisis. In the periodic table, Cu as only the candidate can convert CO2 to C2+ products such as C2H4 and C2H5OH due to the suitable absorption energy to reaction intermediate. Application of Cu is limited for its low activity and poor selectivity.
