摘要: Abstract A novel electrochemical sensor for the detection of formaldehyde with high sensitivity and good selectivity was fabricated, which is composed a low cost environmentally benign MnO 2 film, not noble metals or biological components. The film grown on glassy carbon electrode from aqueous KMnO 4 solution via cathodic mechanism, possessing crystalline birnessite structure pseudocapacitive characteristics.
