Vanadium pentaoxide catalyst is the main ingredient of sulfuric acid production factories, which is also called sulfuric acid catalyst for short. Vanadium pentaoxide with the chemical formula V2O5 is used in the process of SO2 (sulfur dioxide) to SO3 (sulfur trioxide). Naturally, SO2 in the air turns into SO3 and sulfuric acid is produced due to the reaction with air humidity.
