Optimizing Hydrogen Combustion Catalysts for Efficient Stove Design

AI Thread Summary
Building a hydrogen stove using a catalytic approach raises questions about suitable catalysts and combustion temperatures. Nickel is identified as a potential catalyst alternative to platinum, and there is curiosity about using stainless steel materials, such as scotch brite pads or steel wool, for this purpose. Information on combustion temperatures indicates that various catalysts, including copper-doped SnO2, can achieve significant efficiency at relatively low temperatures, with T50% values noted at 250 °C for certain setups. Studies show that platinum and palladium on different supports can yield even lower combustion temperatures, enhancing the feasibility of hydrogen combustion for cooking. Additionally, burner configuration is crucial, as the rapid movement of the flame front necessitates a high hydrogen flow speed for effective combustion.

I am interested in build a hydrogen stove for cooking and wish to use a catalytic stove. I cannot find much information about this anywhere, but only that nickel can be used for hydrogen rather than platinum.

1) Can I just use stainless scotch brite scrub pad as catalyst assuming it contains nickel? Or stainless steel wool?
2) Where can I find information about the combustion temperatures of hydrogen with various catalysts including platinum?

Here is one article with much lower temperatures than a stove:
https://pubs.acs.org/doi/10.1021/acsami.6b08019
(found with: https://www.google.com/search?&q=hydrogen+flame+catalyst)

The catalytic hydrogen combustion on Cu doped SnO2 catalysts was studied and the T50% was found to be 250 °C at a GHSV of 42310 h–1.(34) Hydrogen combustion with both reducible (TiO2) and nonreducible (ZrO2) supports has been studied with Pt and Pd substituted supports at a GHSV of 20000 h–1 and 2:1 ratio of H2:O2. T50% were obtained at 70 and 95 °C with Pd- and Pt-substituted ZrO2 catalysts, whereas Pt and Pd substituted reducible support TiO2 showed much higher activity by reducing temperatures to 37 and 35 °C.

Also pay attention to your burner configuration, the flame front moves rather quickly, generally requiring a high flow speed of the Hydrogen.

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
