I heard that the penta catalyst form Lozano, made up of salts of gold, rhodium, palladium, platinum and silver had it's problems. Info on that can be found about the Frenchman who bought one of his rocket belts. On the other hand, id catalyst production unit worked very well, The Rotary Air Force, out of Saskatchewan Canada used one to make HTP for their peroxide powered gyrocopters, late 90's --> 2007. I used about 45 gal's of their peroxide and except for it being a little high in stantes and therefor not good for silver it was OK MNO2 cat packs which the RAF used..

My idea was to use silver plated Inconel screens to transfer hold the heat.
IE use 98% the silver will quickly all be stripped off and gone, but the
iconel screen  will be very hot...

I don't think this thermal decomposition will work with 85 or 90%, I
think it would have to be 98%.
I also think the thing holding in the heat would have to be something
that could survive 98% decomposition temperatures...

I've wondered if the Lozano "multi-metallic" cat pack
works along some such lines: perhaps the first layers
(which don't encounter the full temperature) are silver,
and then once the reaction is started, it flows over
layers of different materials that are successively
more heat-resistant, but not as active as catalytic
surfaces except at elevated temperatures.
