Applied Catalysis A: General 232 (2002) 203–217 Single step sol–gel made gold on alumina catalyst for selective reduction of NOx under oxidizing conditions: effect of gold precursor and reaction .

Oxidation and reduction are processes that work together in the transfer of electrons that takes place in redox reactions. Oxidation is the process of losing electrons, while reduction is the process of gaining electrons. Oxidizing and reducing agents are the substances directly involved in the transfer of electrons in a redox reaction.

Spontaneous oxidationreduction reactions convert the stronger of a pair of oxidizing agents and the stronger of a pair of reducing agents into a weaker oxidizing agent and a weaker reducing agent. The fact that the following reaction occurs, for example, suggests that copper metal is a stronger reducing agent than silver metal and that the Ag + ion is a stronger oxidizing agent than the Cu 2+ ion.

May 19, 1992· The extraction of these metals in ammonia solutions under the conditions specified, follows the chemical reaction controlled mechanism with an Arrhenius activation energy of about 40 to 90 kJ/mole depending upon the type of ores.

There is a specific type of chemical reaction called oxidationreduction reactions (or redox reactions for short). In these reactions, electrons are transferred from one reactant to another.

OxidationReduction Reactions Introduction Many chemical reactions proceed by an electron (e–) transfer from one reactant to another. These electrontransfer reactions are referred to as oxidationreduction or redox reactions. Oxidation is defined as the part of a redox reaction in which a species loses electrons and
