摘要：

This review summarizes the catalytic-thermal decomposition studies present for tetrafluoromethane (CF4, R-14). CF4 possesses a GWP of 6,630 and has a lifetime of 50,000 years. There are some natural sources of emission present for CF4 but anthropogenic sources are causing an issue. Due to high GWP, it is very important to find sustainable methods to decompose CF4 on a large scale. There are several methods available for the destruction of CF4. Among those methods, the catalytic-thermal decomposition process is one of the most reliable. Its simplicity and lack of harmful by-products make the catalytic-thermal decomposition process a promising method. With the help of a catalyst, decomposition temperature can be reduced. Reduction of temperature makes the process more feasible and economical. There are some limitations to this process such as catalyst poisoning and low input concentration, which need to be resolved.
