Three-dimensional cuprous oxide microtube lattices with high catalytic activity templated by bacterial cellulose nanofibers

We report here on the fabrication of a kind of highly cross-linked network structured cuprous oxide microtube lattices (Cu2O-MTLs) by utilizing a bacterial cellulose membrane as a template. The Cu2O-MTLs showed high specific catalytic activity for methylene blue degradation in the presence of H2O2 under dark conditions.
