This communication explores natural convection of magnetohydrodynamic Blasius and Sakiadis fluid flows with active and passive controls of nanoparticles. The Brownian and thermophoresis effects are added to energy equation. Chemically reactive species are taken into account for first-order and higher-order chemical reactions. The similarity transformation technique is employed to translate the governing partial differential equations into ordinary differential equations and then solved with R-K method with shooting technique. How the velocity, temperature and concentration distributions are effected by distinct physical flow parameters are analyzed and sketched graphically. Skin friction coefficient, local Nusselt and Sherwood numbers are also computed and analyzed with passive and active flows for both Blasius and Sakiadis fluid flows. We found that the Biot number due to thermal enhances the rate of heat transfer rate in active and passive flows for both Sakiadis and Blasius fluid flows.
