Descripción

General description

Phosphoric acid (H₃PO₄) is one of the most important and useful mineral acids. It is used as a catalyst for various organic reactions. It is also used as an inorganic acid electrolyte for fuel cell applications.

Application

Phosphoric acid can be used as an activating agent for the activation of porous carbonaceous materials due to its ability to produce P-containing functional groups in the carbon matrix. These groups are excellent for promoting the formation of carbon micropores, which are useful for developing electrochemical energy storage devices.

Other Notes

El ácido fosfórico concentrado es aproximadamente H₃PO₄ (acuoso) al 85%.
