In this article, we investigate the dynamics of quantum correlation and coherence for two atoms interacting with massless scalar field in the background de Sitter spacetime. We firstly analyze the solving process of master equation that describes the system evolution with initial Werner state. Then, we discuss the degradation, generation, revival and enhancement of quantum correlation and coherence for three cases of different initial states: zero correlation state, nonzero correlation separable state and maximally entangled state.
