Hydroxyl radical and methane
Web7 jul. 2024 · Methane stays in our atmosphere for 12 years. Methane has a relatively short life of 12 years compared to the hundreds or even thousands of years that CO 2 hangs around. After about 12 years, 80 to 89 percent of methane is removed by oxidation with tropical hydroxyl radicals (OH), a process referred to as hydroxyl oxidation. As a result … Web10 apr. 2024 · Then, hydroxyl radical (•OH) forms by attacking the C-H bond to generate •CH 3. Subsequently, the same kind of groups of •CH 3 are coupled to form C 2 H 6 ( Figure 4 d). At the same time, Ti 4+ captures electrons to form Ti 3+ , and Ti 3+ further transfers its electrons to the lattice oxygen to form the interaction between superoxide radicals (O 2− …
