Using a data sample of e+e- collision data with an integrated luminosity of 2.93 fb-1 taken at the center-of-mass energy √s = 3:773 GeV with the BESIII detector operating at the BEPCII storage rings, we measure the absolute branching fractions of the two-body hadronic decays D+ → π⁺π⁰, K⁺π⁰, μ⁺η, K⁺η, π⁺η', K⁺η', $$K_s^0$$π⁺, $$K_s^0$$K⁺, and D⁰ → π⁺π⁻, K⁺K⁻, Kπ±, $$K_s^0$$π⁰, $$K_s^0$$η, $$K_s^0$$η'. Our results are consistent with previous measurements within uncertainties. Among them, the branching fractions for D⁺ → π⁺π⁰, K⁺π⁰, π⁺η, π⁺η', $$K_s^0$$π⁺, $$K_s^0$$K⁺ and D° → $$K_s^0$$π⁰, $$K_s^0$$η, $$K_s^0$$η' are determined with improved precision compared to the world average values.
