Dissolved oxygen is an important parameter in fermentation processes. Here we present oxygen reduction activity of Nitrogen, Boron doped reduced graphene oxide and electrochemically reduced graphene oxide (ERGO) and its application as amperometric sensor for dissolved oxygen. Our study shows that N,B-HRGO, which showed high sensitivity of 0.01 μA / % of oxygen, can be used as an amperometric sensor to sense dissolved oxygen at very low concentration at lower polarization voltage (-0.4 V) compared with ERGO which shows less sensitivity (0.04 μA / % of oxygen) at lower polarization voltage.
