Facile synthesis of uniform yolk–shell structured magnetic mesoporous silica as an advanced photo-Fenton-like catalyst for degrading rhodamine B

Through an ultrasound assisted etching method, uniform yolk–shell structured magnetic mesoporous silica (Fe3O4@void@mSiO2) nanospheres have been fabricated and for the first time demonstrated as an efficient catalyst for degrading rhodamine B under photo-Fenton-like conditions.
