title: Mesoporous bubble-like manganese silicate as a versatile platform for design and synthesis of nanostructured catalysts.
abstract: Manganese silicate in bubble-like morphology was used as a versatile platform to prepare a new class of yolk-shell hybrids. The mesoporosity of the shell was generated from the interbubble space and the bubble structure of manganese silica was used to hold and support nanoparticles (e.g., Au, Ag, Pt, Co, Ni, Au-Pd alloy, MoO2 , Fe3 O4 , carbon nanotubes and their combinations). We also used heterogeneous catalysis reactions to demonstrate the workability of these catalysts in both liquid and gas phases.
