Pd encapsulated by hollow silica spheres for enhanced total oxidation of methane in the presence of water

The particle size control of ruthenium-encapsulated hollow silica sphere catalysts for the hydrogenation of carbon dioxide into formic acid

“…Hollow sphere particles have the advantages of easily controllable shell thickness at the nano size, effective immersion of active species into the inner pores of the shell, and high dispersion of active species in the shell. 15,[18][19][20][21][22][23][24][25][26][27] Their dispersion allows the control of the morphology of hollow spheres, including pore structures. The encapsulated catalysts with precisely controlled morphologies exhibited high catalytic performances.…”
