Possibility of H2O2 decomposition in thin liquid films on Mars

H2O2 is an important and agressive oxidant on Mars. Today liquid interfacial water on Mars is ephemerally present between the water ice and the mineral surfaces, where slow chemical changes might happen, including 2O2 decompositon. The most effective way for this is catalyzed by Fe ions, which could decompose it under Ph<4.5 with half life of 1–2 days. This process might be important during ...
