In recent years, the discovery of efficient catalyst with low price to sulfur dioxide (SO
2
) oxidation in normal temperature is a major concern in the industry. In present study, in first step the boron nitride nanotube (BNNT) with Ge were adopted and the surface of Ge-adopted BNNT via O
2
molecule were activated. In second step the SO
2
oxidation on activated Ge-BNNT surface via Langmuir Hinshelwood (LH) and Eley Rideal (ER) mechanisms was investigated. Results show that O
2
activated Ge-BNNT surface can oxide the SO
2
molecule via Ge-BNNT-O-O* + SO
2
→ Ge-BNNT-O-O*-SO
2
→ Ge-BNNT-O* + SO
3
and Ge-BNNT-O* + SO
2
→ Ge-BNNT + SO
3
reactions. Results show that SO
2
oxidation on activated Ge-BNNT surface via the LH mechanism has lower energy barrier than ER mechanism. Finally, calculated parameters reveal that activated Ge-BNNT is acceptable catalyst with low price and high performance for SO
2
oxidation in normal temperature.
