- •
Bare α-Bi2O3 known as poor photocatalyst was discovered as a terrific MW catalyst.
- •
The MCOD process can efficiently degrade PNP and TOC without adding extra oxidants.

OH generated by MW excited holes acts as primary oxidant in the MCOD process.
- •
The fluorescent probe technique was applied to confirm the existence of border="0" alt="radical dot" data-inlimg="/entities/rad" src="/sd/grey_pxl.gif" class="glyphImg imgLazyJSB">
OH.
- •
A possible catalytic mechanism of MCOD process over bare α-Bi2O3 was revealed.
