How Is Xenon Tetroxide Synthesized?

Xenon tetroxide (XeO4) can be synthesized by reacting xenon gas with oxygen gas in the presence of a catalyst, typically fluorine gas or a mixture of fluorine and oxygen gases. The reaction can be initiated by heating the reactants to around 400-500°C, and the resulting XeO4 can be purified by fractional distillation or sublimation. It is important to note that XeO4 is an extremely reactive and unstable compound, and great care must be taken when handling it to prevent explosions or other hazardous reactions.
