Platinum, adsorption particles, growth

Ikariyama [2] described a unique method for the preparation of a glucose oxidase (GOD) electrode in their work. The method is based on two electrochemical processes, i.e. electrochemical adsorption of GOD molecules and electrochemical growth of porous electrode. GOD immobilized in the growing matrix of platinum black particles is employed for the microfabrication of the enzyme electrode. It demonstrated high performance with high sensitivity and fast responsiveness. 

Adsorption of benzene and its derivatives on the smooth platinum electixjde is slow. The coverage of the electrode surface by chemisorbed particles, at different values of potential and bulk concentrations linearly increase with the growth of time logarithm. The adsorption rate of both benzene and its derivatives can be well described by the Roginslqr -Zeldovioh equation.
