Description

General description

Copper(II) sulfate is an inorganic Lewis acid commonly used to promote acid?catalyzed organic reactions. It is used as a reagent for the synthesis of copper carbenoids. It can also act as an effective redox catalyst in combination with other mixed oxidizing systems.

Application

Copper(II) sulfate pentahydrate can be used to prepare:

• Polydopamine-derived flower-like copper phosphate crystal microstructures with a large surface area.
• Graphene oxide-enzyme based flower-like hybrid nanocomposite materials applicable in wastewater treatment.
