Rocket fuel... I assume you mean hydrazine? You need more than just water/hydrogen peroxide for that right? (Like ammonia?)

  concentrated hydrogen peroxide, if exposed to a catalyst splitting it up again, makes viable a viable thrust source for rockets.

    Right, spray it through a platinum screen, and oxygen gas is liberated.

      Silver screen would work too. Iron oxide would work... Many other substances would catalyze peroxide with various degrees of efficiency.

        I'm not sure what modern peroxide rockets use, but the steam generator in the V2 used sodium or potassium permanganate.

          For an in-depth and interesting explanation of how that works, I enjoyed this video: https://www.youtube.com/watch?v=EgiMu8A3pi0 https://www.youtube.com/watch?v=EgiMu8A3pi0 Includes a demonstration of the potassium permanganate and hydrogen peroxide at around the 52 minute mark.

    Indeed. Used today for the attitude control thrusters on the Soyuz reentry capsule and as a monopropellant for the gas generators on the Soyuz booster rocket.

  hydrazine is N2H4 -- a different fuel https://en.wikipedia.org/wiki/High-test_peroxide https://en.wikipedia.org/wiki/High-test_peroxide

  I took rocket fuel to just mean fuel rockets use. Some of these include highly refined kerosene (RP-1), methane, hydrogen and yes, hydrazine. The point was to ask if these microdoplets could be used to propel a rocket.
