一般說明

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.

應用

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.

其他說明

浓磷酸大约为 85% H3PO4(水溶液)。
