▎ 摘　　要

NOVELTY - The sensor has a sensor basal structure that is composed of rhodium and graphene composite nano-particle to form a rhodium/graphene compound. The rhodium/graphene compound comprises 5 wt% to 20wt% of the nano particle. The average grain diameter of rhodium nano-particle is 2-3nm. The potential of the current detection type sensor is about 0.1V. The basal structure of rhodium/graphene compound is provided with upper cover. USE - Low potential hydrogen peroxide oxidation current sensor. ADVANTAGE - The current mode of Potentiometric sensor detects low voltage (+ 0.1V), and low detection limit concentration without oxygen interference. The preparation process of the sensor is simple with low cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method for low potential hydrogen peroxide oxidation current sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical representation of the linear volt-ampere scanning line of current type sensor. (Drawing includes non-English language text)
