Layer‐by‐layer (LbL) assembly strategies were exploited to decorate wild‐type TMV (tobacco mosaic virus) 1D nanoscaffolds with a totally inorganic, multiredox, tetraruthenate complex belonging to the class of polyoxometalate catalysts. The hybrid capsids give rise to an entangled network of fibrils and ribbon‐like nanoassemblies, whose functional activity was probed towards H 2 O 2 dismutation in neutral water. Combined solid‐state and surface characterization evidence, including Z‐potential, electronic microscopy, thermogravimetry and XPS, delineate a favorable tunability of the nanohybrid material as a function of the added cationic binder.
