The AdS/CFT correspondence allows to calculate RG flows of quantum field theories through its gravity duals. We will discuss a 5-dimensional holographic model, including a dilaton with a potential representing  a sum of  two exponential functions. We will discuss how to generate vacuum and black brane solutions to this model, reducing original equations of motion to Toda lattices. Under the holographic duality the solutions can be related to RG flows at zero and finite temperatures. We will also discuss features of QCD, in particular the dependence of the running coupling  on the energy scale,  that can be reproduced by the constructed holographic RG flows.
