| Abstract: |
The hybrid sulfur cycle (HyS), as one of the most promising thermochemical cycles for hydrogen production, has received widespread attention in recent years. The HyS contains the sulfur dioxide depolarization electrolysis (SDE) reaction that produces hydrogen, and the anodic reaction process that determines the efficiency of the SDE reaction has become a research focus in this field. In this study, high-temperature pyrolysis technology was used to prepare biomass-based carbon materials from corn stover and analyze their catalytic performance when loaded with platinum–chromium bimetal as an anode catalyst in the SDE reaction. The system investigates the influence of the structure of various components of corn stover (cellulose, holocellulose, and lignin), carbonization conditions, etc., on the structure of the stover-based carbon carrier and then uses it to prepare platinum–chromium bimetallic catalysts for characterization and electrochemical analysis. The results show that the holocellulose-based porous carbon has excellent performance, with a specific surface area reaching 519.81 m2/g and a pore volume of 0.65 cm3/g, and the catalyst can achieve a current density of 780 mA/cm2 under a voltage of 1.2 V, showing excellent electrocatalytic performance in the SDE. Therefore, corn stover carbon as a carbon carrier has very high application prospects. [ABSTRACT FROM AUTHOR] |
