A novel α‐zirconium phosphate/polyaniline (α‐ZrP/PANI) hybrid film used as K + ion sensor was fabricated on carbon paper by electrochemical method. Mechanisms of film formation and detection of K + ions were also proposed. The exfoliated α‐ZrP was mixed with PANI and deposited on carbon paper. The resultant α‐ZrP/PANI film exhibited a good current response to K + ion with different concentrations. It also showed a wide logarithmic linear response in detecting K + ions in the ranges of 10 −8 –10 −4 M and 10 −4 –10 −2 M, respectively. The results can be attributed to the synergetic effect of α‐ZrP and PANI.
