Abstract

• Mechanism of DCM disproportionation over mesoporous TiO₂ was studied.

• DCM was completely eliminated at 350℃ under 1 vol.% humidity.

• Anatase (001) was the key for disproportionation.

• A competitive oxidation route co-existed with disproportionation.

• Disproportionation was favored at low temperature.
