By analyzing a data sample of 2.93 fb-1 collected at $$\sqrt{s}$$ = 3.773 GeV with the BESIII detector operated at the BEPCII storage rings, we measure the branching fractions B(D0 → ωη) = (2.15 ± 0.17stat ± 0.15sys) × 10-3, B(D0 → ηπ0) = (0.58 ± 0.05stat ± 0.05sys) × 10-3, B(D0 → η'π0) = (0.93 ± 0.11stat ± 0.09sys) × 10-3, B(D0 → ηη) = (2.20 ± 0.07stat ± 0.06sys) × 10-3 and B(D0 → η'η) = (0.94 ± 0.25stat ± 0.11sys) × 10-3. We note that B(D0 → ωη) is measured for the first time and that B(D0 → ηη) is measured with much improved precision.
