摘要: Abstract The effect of the catalytic property platinum (Pt) on hydrogen adsorption activated carbon (AC) via spillover was investigated. clearly identified from both isotherms and kinetics. Factors, including Pt particle size, loading content AC nature, in platinum-doped (Pt/AC) were considered this study. experiments performed using a volumetric apparatus at room temperature (RT) low pressure (∼0.1 MPa). In study, enhancement factors 16–145% due to obtained for Pt/AC samples because difference textural properties receptors. rate spilt-over is strongly dominated by surface sites as functions crystallite size deposition type (with or without aggregation). When amounted below 0.011 mmol/g, an insignificant observed Pt/AC.
