“…This kind of layer might have facilitated the diffusive exchange of reactant and discharged product by meritoriously suppressing the surface passivation of Zn anode. Dilshad et al 37 had fabricated Zn metal surfaces with and without the additive PEG 600 addition and analyzed the surface characteristics for passivation layers. They conveyed that sharp‐edged particles were observed in both the surfaces, but the PEG 600 expedited smooth, loose and thin‐walled particle surface layers.…”

Summary Zinc (Zn) particles in alkaline electrolyte of a Zn‐air battery (ZAB) are unstable and prone to corrosion. Zinc oxide (ZnO) generated on the surface of Zn particles affects the electrochemical reactions and reduces the battery efficiency. Thus, inhibiting the self‐corrosion rate of Zn particles has become acritical issue for the development of these batteries. In this study, a research endeavor has been attempted by employing three types and concentrations of organic inhibitors in ZABs to constrain Zn anode corrosion. Significant analyses like polarization curve, constant current discharge, AC impedance, and dendrite growth are executed for in‐depth understanding of the influences of these inhibitors. The experimental results reveal that the inhibiting efficiency of 10 wt% Sodium dodecyl benzene sulfonate surpassed polyethylene glycol 600 (PEG 600) and polysorbate 20 (Tween 20), with a maximum current density of 476.20 mA/cm2 and voltage output of 1.4 V along with discharge capacitance of 10.31 Ah for 2 hours and 8 minutes. Zn anode surface analysis exposes significant dendrite growth and elemental Zn required for passivation suppression. Nevertheless, the results are also justified by Nyquist and Bode plots. Thus, the selected inhibitor will proficiently guarantee the enhanced performance and stability of the ZABs obtained and provide enormous opportunities for its applications.

“…Various technologies have been established to remove CO 2 from the feed gas stream, including amine absorption, 7 adsorption, 8,9 membrane, 10 and cryogenic separation 11 . Amine absorption is the most used, but it has many disadvantages, including high energy consumption, corrosion, and low thermal stability 12 . Among these technologies, membrane‐based separation has emerged as a promising technology owing to its simplicity, high product recovery, and low capital cost 13 .…”

Summary Carbon capture and storage (CCS) technologies have gained global attention due to the environmental impact caused by CO2. Ionic liquid, also known as a designer solvent, has good potential for CO2 capture application due to its good CO2 affinity, negligible vapor pressure and high thermal stability. The combination of ionic liquid and membrane technology has been introduced for the more effective use of ionic liquid. This review offers a comprehensive overview of mixed matrix membrane (MMM) and the application of ionic liquid in the membrane for CO2 separation, focusing on recent advances in ionic liquid‐based MMM. Descriptions of various MMM modification strategies using ionic liquid and the influence of challenging operating conditions on the CO2 separation performance of ionic liquid‐based MMM are discussed.

“…According to the aforementioned discussion, polymer-based membranes are generally modified to ameliorate their physicochemical properties and separation performance in various applications. A tremendous number of possibilities of modification on polymeric membranes, including polymer blending [ 15 , 16 ], crosslinking [ 12 , 17 ], surface modification [ 18 ] and the incorporation of additives into polymer matrix [ 7 , 19 , 20 , 21 , 22 ] have been studied. Another alternative approach to modify polymeric membranes is the addition of ionic liquids (ILs) into the polymeric membranes.…”

A new type of hybrid polymeric-based film containing 1-(1,3-diethoxy-1,3-dioxopropan-2-ylo)-3-methylimidazolium bromide (RIL1_Br) and 1-(2-etoxy-2-oxoethyl)-3-methylimidazolium bromide (RIL2_Br) reactive ionic liquids was elaborated. Poly(vinyl alcohol) (PVA)-based films with 9–33 wt % of RILs were subsequently characterized using Fourier transform infrared spectroscopy with attenuated total reflectance (FTIR-ATR), scanning electron microscopy (SEM), atomic force microscopy (AFM), thermogravimetric analysis (TGA) and TGA-FTIR. PVA-RIL films were also studied in tensile tests, contact angle and sorption measurements. RIL incorporation enhanced thermal and mechanical stability of PVA membranes due to the hydrogen bonds between RILs and polymer chains. Membrane swelling behavior in water (H2O), ethanol (EtOH), and propan-2-ol (IPA) and the kinetics of water sorption process revealed that PVA-RILs membranes possess the highest affinity towards water. It was pointed out that both the RIL type and the RIL amount in the polymer matrix have significant influence on the membrane swelling behavior and the water sorption kinetics.
