What are the electrochemical properties of the plasticized β-stannic acid samples?

Label:chem

Topic
The electrochemical properties of β-stannic acid are important for its potential applications in devices such as sensors and fuel cells. The study investigates how the addition of perchloric acid affects these properties.

From: "Vibrational and impedance analysis of the β-stannic acid samples plasticized by perchloric acid", Heliyon, Volume 8, Issue 11, November 2022, e11450
Answer
The plasticized β-stannic acid samples exhibit significantly enhanced electrochemical properties. The proton conductivity increases linearly with the weight fraction of perchloric acid solution (Wpa) up to a certain threshold, reaching a maximum of 0.43 S cm⁻¹ at Wpa = 0.61. The samples also show catalytic properties, reducing the Faraday resistance (RF) by a factor of 6 at low acid concentrations. These properties make the plasticized β-stannic acid suitable for applications in electrochemical devices, particularly hydrogen sensors, due to their high conductivity and fast response times.
