THE activation of copper by repeated oxidation and reduction is ascribed by previous authors to an increase in surface area 1, and our experiments have confirmed this conclusion. In the activated ...

The mounting challenges of climate change, fueled by rising atmospheric CO2 levels from fossil fuel consumption, demand ...

Reduction is the gain of electrons by a substance. It is also the loss of oxygen from a substance. For example, copper(II) oxide can be reduced to form copper when it reacts with hydrogen: ...
