With the increasing variety of Cu-based semiconductor nanomaterials and the development of synthesis technology, the crystal shape and morphology of semiconductor materials have become controllable factors. Due to their low price, abundant reserves, and suitable band gap, Cu-based semiconductor nanomaterials have bright application prospects for the treatment of photocatalytic environments. A comprehensive summary of the basic theory and research progress of Cu-based semiconductor nanomaterials, such as crystal design, morphology control, and photocatalytic modification strategies and mechanisms, is indispensable. However, a comprehensive review of this aspect has not been reported recently. This review summarizes the synthetic methods of copper oxides (CuO, Cu 2 O), copper sulfides (CuS, Cu x S, Cu 2 S), copper selenides (CuSe, Cu 2−x Se, Cu 2 Se), as well as other novel Cu-based semiconductor nanomaterials such as CuFe 2 O 4 , Cu 3 N, Cu 5 V 2 O 10 , CuCo 2 O 4 , CuWO 4 , Cu 3 P, and the application strategies and mechanisms in photocatalytic removal of pollutants, photocatalytic hydrogen evolution, and photocatalytic reduction of CO 2 . The summary of synthesis methods and crystal surface control is beneficial for the preparation of better catalysts. We firmly believe that this review can provide valuable information for the further development of Cu-based semiconductor nanomaterials.

Paracetamol (acetaminophen) is one of the most commonly used pain relievers and fever reducers due to the high stability, solubility, and hydrophilicity; it is mainly detected in pharmaceutical releases. Its presence in aquatic systems is a serious ecological concern. The pharmaceutical industries are using several technologies for separation, extraction, and control such as membrane processes because of their numerous advantages. In the present work, a polymer inclusion membrane containing Tween 20 (TW20) as an extractive agent was fabricated for the treatment and recovery of effluents loaded with emerging pollutants (paracetamol). After characterization of the morphology and porosity, the membrane was adopted to carry out the extraction and recovery processes of paracetamol, assisted by activated carbon. Kinetic and thermodynamic models were applied to determine the values of permeability ( P ), initial flux ( J 0 ), association constant ( K ass ), and diffusion apparent coefficient ( D*) parameters. Subsequently, activation parameters energy ( E a ), association and dissociation enthalpies (ΔH # ass and ΔH # dis , respectively), and entropy (ΔS # ) were measured. For this original technique, the effects of activated carbon on the evolution of processes carried out across the membrane have been investigated and indicate a significant optimization and intensification of the membrane performance and total paracetamol extraction rate. In addition, this technique is clean and does not affect the structure or the stability of the membrane.

Magnetic MgxCoyZn(1-x-y)Fe2O4 nanoparticles were successfully prepared by the rapid combustion approach, and SEM, XRD, VSM, EDX, and FTIR techniques were applied for their characterization. The influence of the element ratios (Mg2+, Co2+, and Zn2+) in magnetic MgxCoyZn(1-x-y)Fe2O4 nanoparticles on their properties was explored. To acquire a larger specific surface area for better adsorption of methyl blue (MB), magnetic Mg0.4Co0.5Zn0.1Fe2O4 nanoparticles calcined at 400°C for 2 h with 25 mL anhydrous ethanol were selected, and their average particle size and the saturation magnetization were about 81.3 nm and 13.5 emu·g-1, respectively. Adsorption kinetics models and adsorption isotherm models were applied to research the adsorption characteristics of MB onto magnetic Mg0.4Co0.5Zn0.1Fe2O4 nanoparticles. The pseudo-second-order kinetics model ( R 2 > 0.99 ) and Temkin isotherm model ( R 2 = 0.9887 ) were the most consistent with the data, indicating that the adsorption was the chemical multilayer adsorption mechanism, and the process was an exothermic reaction. The E of the Dubinin-Radushkevich (D-R) isotherm model was 0.2347 KJ·mol-1, indicating the adsorption involved physical adsorption besides chemical adsorption. The Δ G 0 and Δ H 0 ( Δ H 0 = − 10.38 KJ·mol-1) of the adsorption process of MB adsorbed onto magnetic Mg0.4Co0.5Zn0.1Fe2O4 nanoparticles measured through the thermodynamic experiment were both less than 0, which proved that the process was a spontaneous exothermic reaction. The adsorption capacity of MB onto magnetic Mg0.4Co0.5Zn0.1Fe2O4 nanoparticles increased with the pH of MB solution increasing from 2 to 4 at room temperature, and it had no significant change when the pH of MB solution was 4-12, while the relative removal rate was 98.75% of the first one after 2 cycles. The electrochemical impedance spectroscopy (EIS) and the cyclic voltammetry (CV) data further demonstrated that MB was adsorbed onto magnetic Mg0.4Co0.5Zn0.1Fe2O4 nanoparticles.
