Contact‐electro‐catalysis (CEC) has garnered significant interest as a viable method for degrading organic pollutants. Nevertheless, the current array of catalyst materials for CEC is restricted, and their effectiveness is frequently undermined by environmental influences, resulting in diminished catalytic performance. Herein, a new fluorinated graphite [(CFx)n] catalyst is presented that notably expands the repertoire of available catalyst materials for CEC. It is demonstrated that the (CFx)n catalyst maintains high catalytic activity under nonilluminated conditions and exhibits excellent stability under high‐temperature conditions, surpassing traditional organic polymer CEC catalysts. Furthermore, DFT (density functional theory) calculations reveal the key factors affecting catalytic performance. An in‐depth analysis of the influence of temperature on CEC efficiency is also conducted. The cyclic tests verify that the (CFx)n powders sustain a catalytic efficacy of over 95% and proficiently decompose various organic pollutants, underscoring its promise for large‐scale treatment systems targeting organic pollutants. These results carry significant implications for the progression of CEC technology in environmental remediation efforts and offer valuable direction for the enhancement of catalyst efficiency and stability. Fluorinated graphite [(CFx)n] is being used for contact‐electro‐catalysis (CEC) to degrade organic pollutants for the first time, which maintains high catalytic activity under nonilluminated conditions and exhibits excellent stability under high‐temperature conditions. And conducting an analysis of the influence of temperature on CEC efficiency, holding significant importance for advancing CEC research.
