It was mentioned in Godzilla vs. Destoroyah and Godzilla against Mechagodzilla.

Godzilla vs. Destoroyah: The Oxygen Destroyer would've been more dangerous than any weapon before or after its time. While Micro Oxygen shows some similarity to the Oxygen Destroyer, it lacks the former's destructive abilities that Destoroyah possesses.

Godzilla against Mechagodzilla: Serizawa feared the power he unleashed, and refused to share it with the world. He took it to the grave with him.

In the Godzilla/Gojira film: Serizawa is told that he has a responsibility that no one has ever had before because of both the Oxygen Destroyer and Godzilla/Gojira. He had his fear (the Oxygen Destroyer) that may become reality (being used to replace all other weapons used in the arms race), and he had Godzilla/Gojira, which was reality (destroying Japan and soon the world). So he agreed to use the weapon, but destroyed his research his papers to ensure that the weapon could never be used more than once, and then took his own life to keep from being made to duplicate his research.
