Corrosion poses a significant problem for several industrial sectors, inducing continuous research and development of corrosion inhibitors for use across a wide range of industrial applications. Here, we report the effectiveness of three newly developed Schiff bases derived from amino acids and 4-aminoacetophenone, namely, , , and , as environmentally friendly corrosion inhibitors for Q235 steel in hydrochloric acid using electrochemical and surface analyses, in addition to theoretical techniques. The electrochemical findings of potentiodynamic polarization (PDP) demonstrated that the explored compounds serve as mixed-type inhibitors and can effectively suppress steel corrosion, with maximal protection efficiencies of 93.

In this contribution, mesoporous n-n heterojunction LiMnO/WO nanocomposites were designed via a simplistic sol-gel process for CO reduction utilizing visible illumination (λ > 420 nm). XRD and TEM measurements confirmed the synthesized LiMnO/WO nanocomposite is a monoclinic structure, and its particle size is 25 ± 5 nm.

In this study, the heterojunction mesoporous α-FeO/TiO modulated with diverse Ag percentages has been constructed via a sol-gel route in the occurrence of a soft template P123. The formation of biphasic crystalline TiO anatase and brookite phases has been successfully achieved with the average 10 nm particle sizes.

Herein, porous Au/TiO synthesized by pyrolysis of NH-MIL-125(Ti) was utilized to be an efficient photocatalyst for mineralization of trimethoprim (TMP) and Metronidazole (MNZ) as the parent compound. The effects of different factors, including TMP and MNZ concentrations, light intensity, HO concentration, Au/TiO dosage, and pH value of reaction solution on the degradation and mineralization performances during UV and visible light (VIS), were addressed.
