Nickel oxide modified screen-printed carbon Electrode

110NI

Description

Screen-printed electrodes (SPEs) are electrochemical platforms manufactured by printing a wide variety of inks over different substrates allowing rapid on-site analysis with high reproducibility, sensitivity and accuracy.

Features

Number of WEs: 1 WE
Working electrode material: Nickel (II) oxide/carbon
Auxiliary electrode material: Carbon
Reference electrode material: Silver
Contacts material: Silver
Substrate material: Ceramic
Substrate size: Length: 3.38 cm x Width: 1.02 cm
Substrate thickness: 0.05 cm
Main features:

Single to use sensors that eliminate the electrode maintenance. Specially designed to work with microvolumes, this inexpensive miniaturized solution presents high reproducibility making them ideal for working in decentralized assays or to develop (bio)sensors in environmental, clinical or agri-food areas. The different modifications applied to the working electrode provide an enhanced active area and improve the electron-transfer properties.

Possible applications:

Electrocatalysts for the electrochemical oxidation of small organic molecules such as carbohydrates, amino acids and alcohols. Also,this electrochemical platform is useful for developing other (bio)sensing applications in multiple sectors and fields.

Additional information:

For best results in catalytic processes, pretreatment of the electrode is recommended:

Electrochemical method: cyclic voltammetry.
Supporting electrolyte: 0.1M NaOH (50┬ÁL).
Conditions:
teq = 3″; nScan = 15
E0 = + 0.1 V; Evrtx,1 = + 0.7 V; Evrtx,2 = + 0.1 V
Estep = 2 mV; Srate = 50 mV/s
Then wash the electrode with ultrapure water.
