A sustainably promising way to overcome these shortcomings is to deploy neutral/near-neutral electrolytes for electrocatalysis reactions. Unfortunately, insufficient research in this area due to the lack of attention to related issues has slowed down the development process. In this review, we systematically review the catalytic reaction mechanisms, neutral electrolytes, electrocatalysts, and modification strategies carried out in neutral media on the three most common electrocatalytic reactions, that is, hydrogen evolution reaction, oxygen reduction reaction, and oxygen evolution reaction. Furthermore, the advanced characterization tools for guiding catalyst synthesis and mechanistic studies are also summarized.

Due to the 97.5% <i>β</i>-phase content and aligned structure, a piezoelectric constant of 20 pC/N is achieved in the three-times folded film. Furthermore, the process method enhances the tensile strength (126.2 MPa) of the films, with a low Young's modulus (0.87 GPa) remaining, making the films applicable for flexible piezoelectric sensors.
