Pore size-controlled synthesis and characterization of nanostructured silica particles

Synthesis of micron-sized porous CeO2SiO2 composite particles for ultraviolet absorption

“…Otherwise, the porous structure exhibited improved photo-stability and UV protection effects [20]. Moreover, porous composite particles can easily contain additive meso-and macro-pores to enhance the UV absorption ability [21]. However, to the best of our knowledge, the synthesis and UV absorption of micron-sized porous CeO 2 ASiO 2 composite particles have never been previously reported.…”

“…The PSL particles were used as a pore template. The spherical PSL particles, 200 nm in diameter, were synthesized from a styrene monomer according to the method in previous reports [21,22]. CeO 2 nanoparticles less than 10 nm in diameter were synthesized from cerium nitrate hexahydrate (Ce(NO 3 ) 3 Á6H 2 O, Sigma Aldrich, 99%) by means of flame spray pyrolysis (Fig.…”

Synthesis of hierarchical structured porous MoS2/SiO2 microspheres by ultrasonic spray pyrolysis

“…For comparison, SiO 2 microspheres were also prepared according to a literature procedure (Iskandar et al, 2001(Iskandar et al, , 2002(Iskandar et al, , 2003Thill and Spalla, 2005;Okuyama et al, 2006;Chang et al, 2008;Widiyastuti et al, 2010). Typically, a designated amount of LUDOX ® SM-30 colloidal silica was dissolved into 100 mL of distilled water.…”
