Steam activated bamboo biochar Manganese Metal Organic Framework (Mn-MOF) water filter and battery

IDEA
Steam activator adapter for a Navigator 'Awesome' V2 TLUD (see 'Bush Survival System' page) that can steam activate Biochar pellets for MOFs used in water filtration and batteries.

Steps for Metal Organic Framework (MOF)
1. Grow, harvest, dry, grind and pelletise bamboo
2. TLUD Pyrolysis of bamboo pellets (Navigator 'Awesome' V2) for first batch to be activated in next step
3. TLUD steam activation of Biochar pellets using TLUD steam activator adapter attached to Navigator 'Awesome' V2 (producing more Biochar pellets during pyrolysis for subsequent steam activation)
4. Mill steam activated Biochar pellets into powder
5. Build a MOF. Soak steam activated Biochar powder in Mn salts and organic linkers at room temperature in 'One pot'. 'Self assemby' of the Mn salts and organic linkers should occur via C-O-M coordination bonds...
6. Wash the MOF

7. Dry the MOF
Finished ☺️

Equipment
- grinder
- Pelletiser
- Navigator 'Awesome' V2 TLUD
- steam activator
- to be designed and built - any ideas?
- biochar mill

Applications
- water filtration using the MOF in the Permafilter 20L/other water filtration system
- battery anodes, ?cathodes, ?solid state electrolytes with the MOF - a HOT area of research!

Comments

-Could be a lab-scale system for designing a scaled up industrial system for water filters and batteries

-Could be a cottage industry for small-scale water filter and battery manufacturers - potentially, regionally manufactured modular battery housings could be designed to work with the MOF, or the whole battery could be manufactured at one regional factory. The Mn salts and organic linkers might be tricky to get if making the MOFs in a remote location.

-there's a lot of science around this topic to research but from what I can gather so far, I see this idea as a real possibility for water filter and battery manufacturers

-research needs to be done around Mn toxicity in water filtration media for potable water for human consumption. Potentially, if the Mn-MOF cannot be tested as 'safe', the steam activated biochar (Activated Carbon) should be used for water filtration before proceeding to the MOF stage of material engineering. The Mn-MOF can be still used for contaminated water, such as mine site heavy metal water contamination, for environmental remediation
