12-tungestocobaltic acid, H5CoW12O40, was immobilized on nano silica from rice husk (CoW@NSiO2) to develop a novel, efficient, heterogeneous and recyclable nano catalyst for the synthesis of β-enaminones. It is apparent from acidity and cyclic voltammetric measurements that, the catalyst is electroactive and undergoes reversible redox transitions, as well as it is contains strong acid sites and mobile
