This study reports the synthesis and characterization of template free nano sized ZSM-5 zeolite. The Synthesized ZSM-5 zeolite with an average particle size of 60 nm was synthesized using clear solution at 180 °C under autogenously pressure. The synthesized zeolite was characterized using X-ray diffraction, FT-IR and scanning electron microscopy techniques. Then it was used to prepare a new zeolite-modified carbon paste electrode (ZMCPE) based on the Ni-MFI type zeolite for formaldehyde electrocatalytic oxidation. The incorporation of Ni (ІІ) ions into the zeolite framework was done by the immersion of synthesized zeolite in a 0.5 M nickel chloride solution for 5 h. After the preparation of modified carbon paste electrode using the synthesized zeolite, the electrocatalytic oxidation of formaldehyde in alkaline solution was investigated using the cyclic voltametry method. Transfer coefficient (α = 0.51) as a kinetic parameter was calculated.
