Simple synthesis of multiple length-scale structured Nb2O5 with functional macrodomain-integrated mesoporous frameworks

Abstract

We report the simple synthesis of macro-and mesostructured Nb2O5 that have functional submicrometer-sized particles (macro-domain) 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.
