Photocatalytic oxygen activation is an excellent strategy for algae control in water. However, the fast recombination of photogenerated charge and slow rate of oxygen transfer limit the reactive oxygen species generation efficiency for algae inactivation. Herein, to solve above issues, magnetic field was introduced to the BiO 2−x /Bi 3 NbO 7 system …

The Spanish team started by looking at the anode, where the oxidation of water to oxygen takes place. This half-reaction requires a lot of energy and is typically the bottleneck in water splitting. 'Now, we demonstrate that magnetic fields increase water oxidation rates, and this can be easily implemented,' explains Galán-Mascarós.

Answer. Actually it is not magnetic but paramagnetic. That is that it is attracted by the magnetic field but does not remain magnetic once it leaves the field. Gaseous oxygen is paramagnetic also but is moving too fast to be affected by the magnets. The reason that it is paramagnetic is because the oxygen molecule has two unpaired electrons.

The maximum magnetization you're likely to get with any permanent magnet (not achieved to date) is about 50 Tesla, or 40,000 ampere meters. At 20°C, the per-mol, magnetic susceptibility of oxygen is 1.34×10 −6 This suggests that the Curie constant is 1.34 ×10 −6 x 293 = 3.93 ×10 −4. Applying this value to oxygen in a 50 Tesla magnet ...
