“…Porphyrin derivatives, designed to easily distort their planar geometry, are highly recognised for their capacity to act as sensitive materials in formulations of optical [ 1 , 2 ], fluorescent [ 3 , 4 ], potentiometric [ 5 , 6 ] and electrochemical sensors [ 7 , 8 ]. More structures of diversely substituted porphyrins and metalloporphyrins proved their utility in acting as corrosion inhibitors for carbon–steel devices, working in both saline [ 9 , 10 , 11 ] and aggressive acid media [ 12 , 13 ]. Recently, as the global energy demand increases, and because hydrogen is considered to be a sustainable choice [ 14 , 15 ], its generation via the electrochemical water splitting method [ 16 , 17 ] involves porphyrins and metalloporphyrins as catalytic materials [ 18 ].…”

Porphyrins are versatile structures capable of acting in multiple ways. A mixed substituted A3B porphyrin, 5-(3-hydroxy-phenyl)-10,15,20-tris-(3-methoxy-phenyl)-porphyrin and its Pt(II) complex, were synthesised and fully characterised by 1H- and 13C-NMR, TLC, UV-Vis, FT-IR, fluorescence, AFM, TEM and SEM with EDX microscopy, both in organic solvents and in acidic mediums. The pure compounds were used, firstly, as sensitive materials for sensitive and selective optical and fluorescence detection of hydroquinone with the best results in the range 0.039–6.71 µM and a detection limit of 0.013 µM and, secondly, as corrosion inhibitors for carbon–steel (OL) in an acid medium giving a best performance of 88% in the case of coverings with Pt-porphyrin. Finally, the electrocatalytic activity for the hydrogen and oxygen evolution reactions (HER and OER) of the free-base and Pt-metalated A3B porphyrins was evaluated in strong alkaline and acidic electrolyte solutions. The best results were obtained for the electrode modified with the metalated porphyrin, drop-casted on a graphite substrate from an N,N-dimethylformamide solution. In the strong acidic medium, the electrode displayed an HER overpotential of 108 mV, at i = −10 mA/cm2 and a Tafel slope value of 205 mV/dec.

“…This is due to the high porosity of the PANI matrix (∼11.51% after 30 days), , which allows passing the corrosive ions through the matrix pores to reach the Mg electrode to start the corrosion process . The incorporation of 3D-FCNT nanoparticles inside the PANI matrix-forming PANI@3D-FCNT nanocomposite can help in healing the porosity of the PANI by reducing the pore size of the PANI (∼1.3% after 30 days). , The Brunauer–Emmett–Teller (BET) method verified that the addition of 3D-FCNT to the PANI matrix reduced the total pore volume of the PANI@3D-FCNT nanocomposite from 0.743 to 0.194 cm 3 g –1 . This causes an increase in the anticorrosion efficiency of the PANI@3D-FCNT nanocomposite to 93.9% and R ct to ∼1840 Ω cm 2 .…”

A promising potential device for storage of large amounts of energy is Mg−air batteries. However, the corrosion of the Mg electrode inside the battery electrolyte limits the battery's capacity to store energy. We present a new strategy to protect the Mg electrode from corrosion and increase the life cycle of Mg batteries in this article. The Mg electrode is coated with a conductive nanocomposite

“…It is widely known that the materials used for traditional battery separators are mainly polypropylene and polyethylene, but these materials have poor thermal stability and chemical corrosion resistance. Therefore, in recent years, researchers have begun to explore new types of membrane materials, including composite materials [4][5][6][7] . The types of fillers for composite materials are also considered.…”

The polyvinylidene fluoride/graphene composite membranes were prepared by electrostatic spinning under different conditions. Statistical analysis was conducted on the film-forming properties and liquid absorption rate. Scanning electron imaging technology observed the typical morphologies of the prepared membranes. The influences of process conditions, such as the graphene content, the applied voltage, the needle-collector distance, and the spinning flow rate on the typical morphology of the composites, were compared. It was found that the applied and the needle-collector distance significantly affected the thin film’s film-forming properties. In contrast, the flow rate had a smaller effect on the film properties and morphology. Comprehensive comparison results suggested that the morphology and uniformity of the fibers in the prepared composite material were relatively better at the needle-collector distance of 13 cm with a graphene content of 0.5%, the applied voltage of 18 KV, and the spinning flow rate of 0.12 μL/min.
