Models presented in the 2021 IPCC report suggest that if the climate policies are kept the same, the average temperature is predicted to increase by 2.5 to 2.9ºC by 2100, causing deleterious effects on living beings . In 2021, fossil fuels (including oil, natural gas, and coal) accounted for 77% of global energy consumption. Moreover, between 2020 and 2021, there was a staggering 17% increase in fossil fuel consumption . One of the directions for tackling global warming and our dependency on fossil fuels is to convert the emitted CO 2 in the so-called high-value products, a process named CO 2 reduction reaction (CO 2 RR). Over the past years, the scientific community has devoted considerable attention to this area, leading to a wealth of published articles that explore diverse materials and methodologies aimed at establishing a closed CO 2 cycle . Figure (yellow) depicts the rising trend in works regarding CO 2 and CO reduction reaction as topic.
