“…Fu et al built a modified Znmetal anode surface via Sn flakes retexturing as shown in Figure 2C. Compared to the Zn/Sn (101) and the bare Zn, the preferential orientation of Zn/Sn (200) not only contributes to the lower deposition energy barrier, which promotes Zn deposition kinetics but also induces the lateral growth of Zn crystals. 54 Benefiting from the strong points, the Zn/Sn (200) shows lower voltage hysteresis of about 20 mV, as well as a better cycle lifetime over 500 h at 1 mA cm −2 with the restrained Zn dendrite formation.…”

The need for large‐scale electrochemical energy storage devices in the future has spawned several new breeds of batteries in which aqueous zinc ion batteries (AZIBs) have attracted great attention due to their high safety, low cost, and excellent electrochemical performance. In the current research, the dendrite and corrosion caused by aqueous electrolytes are the main problems being studied. However, the research on the zinc metal anode is still in its infancy. We think it really needs to provide clear guidelines about how to reasonably configure the system of AZIBs to realize high‐energy density and long cycle life. Therefore, it is worth analyzing the works on the zinc anode, and several strategies are proposed to improve the stability and cycle life of the battery in recent years. Based on the crystal chemistry and interface chemistry, this review reveals the key factors and essential causes that inhibit dendrite growth and side reactions and puts forward the potential prospects for future work in this direction. It is foreseeable that guiding the construction of AZIBs with high‐energy density and long cycle life in various systems would be quite possible by following this overview as a roadmap.

“…At specific pH values, the OLE may exhibit greater potential in generating a protective film on the metal surface. many studies revealed that when decreasing the pH from 8 to 3.9, different changes were observed in the corrosion potential after adding the inhibitor and that the efficiency of the inhibitor decreases with increasing acidity, and also the weight loss decreases with increasing the pH from 3.15 to 8.0 22 , 23 It was noticed in the practical results that as the acidity of the solution increased and the pH decreased, the effectiveness of the extract decreased. Therefore, comprehending the correlation between pH and its impact on the efficacy of OLE as a corrosion inhibitor is of utmost importance in optimizing its usage.…”

Corrosion constitutes a significant issue in industries that handle metals. Corrosion inhibitors with a low impact on the environment provide a significant economic benefit in various engineering applications. In this work, the effectiveness of olive leaves extract is evaluated as a cost-effective and environmentally-friendly corrosion inhibitor. The corrosion of carbon steel in different concentrations of hydrochloric acid (0.1, 1.0, and 2.0 M) when protected by an aqueous solution of olive leaf extract of concentrations ranging from 10 to 60 ppm is investigated. A green extraction process based upon water extraction is used to ensure minimum impact on the environment. Results show that the corrosion inhibition efficiency increased as the concentration of the olive leaf extract increased. An analysis of variance showed a significant effect of acidic molarity, temperature, and inhibitor concentration on the corrosion rate. A significant statistical model indicates that the inhibitor exhibits higher efficiencies at higher acidic molarity. Results of SEM and EDX also demonstrated that a protective film of the inhibitor on the specimen surface plays a role in corrosion inhibition, suggesting that the inhibitor molecules are adsorbed at the interface between the carbon steel and the acid solution. The study provides an insight on the corrosion mechanism and highlights the potential of olive oil extract as an eco-friendly alternative to traditional corrosion inhibitors.

The influence and susceptibility of chloride ion concentration, temperature, and surface roughness on corrosion behavior of single‐phase CoCrFeNi medium‐entropy alloy (MEA) was examined in NaCl solution. Potentiodynamic polarization results revealed that the corrosion performance of the sample deteriorated with an increase of the chloride ion concentration, temperature, and surface roughness. The pitting potential decreased drastically for samples with higher surface roughness. According to electrochemical impedance spectroscopy, the charge transfer resistance decreased when chloride ion concentration, temperature, and surface roughness increased. Scanning electron micrographs also indicated an increased extent of corrosion damage, especially for the sample with higher surface roughness. It is found that the corrosion resistance is closely related to the wettability of samples, and the surface with the highest roughness shows higher hydrophilicity. The combined results suggested that the pitting damage is more sensitive to surface roughness. Our findings provide a further understanding of the corrosion mechanism of MEAs and guide their applications as structural materials.
