The structure of porous silica particles can be reorganized without alteration of the particle size and shape by the process of pseudomorphic transformation. Partial pseudomorphic transformation leads to ordered mesoporous silica with bimodal pore size distributions and bottleneck pores. Compared to the classical pathways of mesoporous silica synthesis, pseudomorphic transformation implies less compromise between pore structure and particle shape, while enabling the preparation of complex pore architectures.
