Abstract

We report the simple synthesis of macro- and mesostructured Nb₂O₅ that have functional submicrometer-sized particles (macrodomain) embedded in mesoporous frameworks (nanodomain). Resol can macrophase-separate by self-polymerization and co-assemble with niobia sol into mesostructured frameworks. The resultant materials increase the power conversion efficiency due to light-scattering capability of submicrometer-sized particles.
