How to semi save the world from getting warmer.

Ce-Rh Theory For Reducing Global Warming​

Ce and Rh​

Cerium switches between two oxidation states
Ce4+<>Ce3+
This makes cerium oxide, CeO2 is good at storing and releasing oxygen. Oxygen in CeO2 can work in redox reactions.
Rhodium is a effective transition metal catalyst. Rh surfaces activate such as CO, H2 and hydro carbons, making difficult reactions happen at low temperatures.

So the combination is
CeO2 provides oxygen storage/redox chemistry, and Rh provides active places for breaking and rearranging greenhouse gas molecules.

Methane​

Methane is much more effective in trapping heat than CO2 over short time lengths. One possible thing would be using a CeO2–Rh to destroy methane before it reaches the atmosphere.

The reaction is:
CH4+2O2>CO2+2H2O
This doesn't eliminate carbon but it converts methane into CO2 but it can significantly reduce the short term warming effect of the carbon.
The interesting part is how CeO2 could help Rh.
At the catalyst base, Ce4+/Ce3+ can provide reactive oxygen, while Rh activate the C-H bonds in the methane.

A simpler cycle is
CH4RhCHx∗
Then with oxidation:
CHx*+O*>COx+H2O

CO₂ recycling​

You could take it further and try to convert CO2 into chemicals or fuels that can be useful.
One possible Reaction is CO2+4H2>CH4+2H2O
This is CO₂ methanation.
The issue is making methane only helps climate change if hydrogen comes from a low carbon source and methane is contained and recycled and not released.

Another route is producing carbon monoxide
CO2>CO
CO can be used as stock for the chemical synthesis.
CeO2 is weird because its oxygen can interact with CO2
CO2+VO>CO+O
VO represents the oxygen vacancy.
Rh could maybe isolate the reactions used to break and redo the CO2. But its just a theory. None of you are gonna read ts, high effort asf too.

Catalytic methane removal is too difficult, atmospheric methane at ~2ppm means you're going to need to process a shitton of air

Methane oxidation also requires a shitton of heat (300-600 CELSIUS) so you'll need a shitton of energy to maintain these temps, it would be retardedly expensive to run all this + having to get global-scale amounts of rhodium where its ~300k a kg

Chemistry is mostly correct, think ur reduction equation isn't entirely correct, but practically this is a little more possible than an Alcubierre drive

Honestly bro high IQ theory, if a catalyst that oxidizes methane works at ambient temp is invented then we would need only about 10^5 TWh (about 3x current electricity generation) compared to 25 million TWh--I did a rough calculation--10^5 TWh for a full atmospheric pass is attainable with fusion (25 million is not even if we get the generation because waste heat from fusion reactors would rape the earth at around 10million TWh)
