Novel iron-doped aluminogermanate nanotubes were obtained using a single step, aqueous phase synthesis protocol. These nanotubes are isostructural with imogolite, a natural occurring nanofiber, but are obtained by-product free in substantially larger quantities with aluminum substitution levels around 1%. Increasing the Fe concentrations led to higher substitution levels but also to the co-precipitation of Fe (oxy)hydroxides.
