New black silicon-supported catalyst for photoreduction of #CO2 to #methane #UofT

New black silicon-supported catalyst for photoreduction of #CO2 to #methane #UofT

a) Schematic diagram of a methane power plant and broadband solar fuels reactor integrated into a natural gas network cycle that recycles CO2 to CH4 . (b) A schematic diagram illustrating the idea of a thin catalyst film that utilizes UV- and visible photons to split water can be deposited on top of the Ru/SiNW catalyst. Hydrogen generated from the water-splitting reaction can be provided to the Ru/SiNW catalysts. NIR photons transmitted through the water-splitting catalyst can then be used to activate the Sabatier reaction over the Ru/SiNW catalyst. (c) The Ru/SiNW catalyst could also be placed below a reactor that uses UV- and visible photons to generate hydrogen from liquid water. In this tandem configuration the generated hydrogen can be exposed along with CO2 across the surface of the Ru/SiNW catalyst. NIR photons transmitted through the reactor can then activate the ...

I like that the measurements of the outfits are listed so it helps me to find the right fit for me. The delivery was equal...
