To prepare the Pt/r(GO-ZSM)/GF electrode, GO-ZSM-5 composite was prepared by simple 1:1 mechanical mixing which was coated over graphite foil and electrochemically reduced at a current density of (-)1 mA.cm-2. The electro-chemical studies, such as cyclic voltammetry and chronoamperometry established that Pt/r(GO-ZSM-5)/GF electrode exhibited better tolerance towards CO-poisoning compared to Pt/rGO/GF electrode. The larger IF:IB value for Pt/r(GO-ZSM)/GF indicated much lesser carbonaceous accumulation on the zeolite modified electrode. The peak current density was comparable for both Pt/r(GO-ZSM-5)/GF and Pt/rGO/GF electrodes. Thus ZSM-5 was instrumental in reducing the catalyst poisoning without compromising with the current density. The findings of the investigation can prove useful in the search of solution for the problem of catalyst poisoning associated with platinum electrodes. %U https://amp.iaamonline.org/article_15963_d938991a0bbd8368a153e840e2b7cba0.pdf
