Abstract

An electrode that comprises a nanostructured material that comprises pyrolyzed date palm leaves that are obtained from a pyrolysis of an agro-waste containing date palm leaves in an inert gas and in a temperature range of 800 to 1600° C., an electrochemical cell thereof, and a method of determining a hydroquinone concentration in a hydroquinone-containing solution with the electrochemical cell. Various combinations of embodiments are also provided.

First claim

The invention claimed is:

1. An electrode, comprising:
a nanostructured material comprising pyrolyzed date palm leaves,
a conductive metallic substrate, and
an insulating material,
wherein the nanostructured material is disposed on the conductive metallic substrate,
wherein the insulating material at least partially covers the nanostructured material disposed on the conductive metallic substrate,
wherein the nanostructured material has a thickness in the range of 10 to 1,000 μm, and
wherein the pyrolyzed date palm leaves are obtained from a pyrolysis of an agro-waste comprising date palm leaves in an inert gas and in a temperature range of 800 to 1600° C.

2. The electrode of claim 1 , wherein the inert gas is selected from the group consisting of nitrogen, helium, neon, and argon.

3. The electrode of claim 1 , wherein the agro-waste consists of date palm leaves.

4. The electrode of claim 1 , wherein the nanostructured material further comprises at least one element selected from the group consisting of oxygen, nitrogen, iron, silicon, potassium, and calcium.

5. The electrode of claim 1 , wherein the nanostructured material is porous with an average pore size of 1 to 10 nm.
