摘要: Abstract Composite hollow silica microspheres containing embedded iron oxide nanoparticles for radiofrequency heating have been synthesised by a soft templating route. The influence of nanoparticle concentration on the size distribution, shell thickness, and rate was investigated. structure characterised SEM, confocal microscopy BET analysis, temperature-dependence release kinetics model substance (vitamin B12) from measured time-resolved UV/Vis spectrophotometry. A mathematical process, based simultaneous diffusion adsorption/desorption solute in mesoporous shell, has developed used to evaluate dependence effective diffusivity temperature preparation conditions.
