Zusammenfassung:•Facile and highly effective preparation of monodispersed ultra-large mesopore MSNs is realized.•Ultra-large mesopores (over 20 nm) and monodispersed ULP-MSNs are available.•Sodium borohydride-enhanced Ostwald ripening process plays a key role in preparation.•Tunable ultra-large mesopores and controllable particle sizes of ULP-MSNs can be produced in a facile manner. This work reports the facile synthesis of monodispersed ultra-large mesopore mesoporous silica nanoparticles (ULP-MSNs) through a new and simple NaBH4-assisted hydrothermal process (NAH process). Such preparation of ULP-MSNs enables the small mesopore size (
