    Peace,


    How can I split CO2? I have heard about Bosch reaction, but I dont know how to make it happend. Can anyone give me instruction how to make it happend? Also, other ways are fine, and I am interested to know all kinds of different ways how to split CO2, but I need instructions also.

    Thank you for your kind responsies.

    The reverse water gas shift reaction is one way, but it's not something you can do easily in your kitchen. And it only goes to CO, not all the way to C.

    Thanks. Its ok if it is complex. How would you do it? I need to get solid carbon (graffit).

    Why not just buy a package of pencil lead?

    You don't have to split CO2 to get carbon. You could just hold a cold mirror in a candle flame.

    So, you want to find a way to split CO2. In other words, you want to take, for example, CO2 you breathe out and split it into C and O2. One way to do this (I read somewhere) is by burning CO2. This would would be extremely, extremely inefficient in my opinion. Another method I read was in the "TheNakedScientists" forum: someone said a "zirconium oxide electrolysis cell" could possibly break it down as well.

    The method I think is best: grow a plant. It will use CO2 and through photosynthesis, make O2 and glucose.

    Technically, plants fix CO2 and produce glucose, the O2 is produced by breaking H2O during photosynthesis.

    I want to brake CO2 to C graffit and O gas. Dont mind if it produses other molecyles as well during the process. I heard about Bosch reaction but I dont know how to make it. If anyone can tell where to find instructions it would be also cool.


    thanks.

    I'm normally all about home projects, but I don't think the Bosch process is possible without specialized industrial equipment. You have to mix CO2 with hydrogen gas in a closed environment and heat it to 450+ C under high pressure in the presence of an iron catalyst. Also, the reaction releases heat, so you have to regulate the temperature and the pressure to keep your closed container from bursting.

    I really, really doubt that can be done outside an industrial setting.

    Thanks, I have my doupts too about that, but it would be nessessary to get all valid information before determing that. It can take years, as always, to actually reach the goal. hehe, but usually the way is more benefitial than the actual goal.

    You happend to know where person can find instructions how to make Bosch reaction?


    Thanks for the kind response.

    If you think you cab do it go for it.The Bosch reaction is also being investigated for use in maintaining space station life support. Though the Bosch reaction would present a completely closed hydrogen and oxygen cycle which only produces atomic carbon as waste, difficulties maintaining its higher required temperature and properly handling carbon deposits mean significantly more research will be required before a Bosch reactor could become a reality.

    One problem is that the production of elemental carbon tends to foul the catalyst's surface, which is detrimental to the reaction's efficiency.

    is there another enzyme or material that could mixed co2 with h2o to become some solid things?
