  In this paper, we consider dyonic charged AdS black hole which is holographic
dual of a van der Waals fluid. We use logarithmic corrected entropy and study
thermodynamics of the black hole and show that holographic picture is still
valid. Critical behaviors and stability also discussed. Logarithmic corrections
arises due to thermal fluctuations which are important when size of black hole
be small. So, thermal fluctuations interpreted as quantum effect. It means that
we can see quantum effect of a black hole which is a gravitational system.
