  In this paper, we consider an $\alpha^{\prime}$ corrected
Reissner-Nordstr\"{o}m AdS black hole to study thermodynamics. We study the
$P-V$ criticality and thermodynamical stability of the black hole. We obtained
a first-order phase transition, which may be interpreted as the large/small
black hole phase transition. Therefore, we obtained a van der Waals behaviour
and obtained critical points. Finally, we calculate quantum work used to
resolve the information loss paradox.
