Platinum is a well known element that shows a significant electrocatalytic activity in many important applications. However, bare platinum electrodes are low sensitivity and poor selectivity in glucose detection. We presented this work that porous platinum electrode decreases such disadvantages. Nanoporous metals having very high surface area have attracted considerable amount of research work, because they have diverse possibilities of application, i.e. catalysis, fuel cells and sensors etc. In this report, we fabricated porous Pt by alloying-dealloying method. First, porous electrode was made of Pt wire which has electrochemically deposited zinc on its surface. Later then, Pt-Zn alloy was deealloyed electrochemically to obtain nanoporous surface structure. We proved that porous Pt is sensitivity by showing response of H2SO4, methanol and SEM images. This work was supported by the Energy & Resource of the Korea Institute of Energy Technology Evaluation and Planning (KETEP) grant funded by the Korea government Ministry of Knowledge Economy (No. 2010501010002B)
