摘要：
We use the dark energy density of holographic methods to reconstruct f(R) in Weyl- f(R) gravity. We analyse f(R) by assuming that the combination of f(R) together with the Weyl gravity might actually be an effective description of dark energy models. The reconstructed model in the spatially flat FRW universe is considered for three version of scale factors: phantom, quintessence and de Sitter scale factors. For the de Sitter scale factor we also obtain the equation-of-state parameter.
