Effect of resorcinol to melamine-formaldehyde aerogel catalyst
摘要
Abstract
Melaimne-resorcinol-formaldehyde( MR) nitrogen contained carbon aerogeK MR-CA) was prepared through the steps of sol-gel,solvent exchange,freeze-drying and carbonization using melamine,resorcinol and formaldehyde as raw materials. The results of specific surface area and microporous analysis showed that the pore size of MR aerogel was 5 - 40 nm, the average pore size was 15.5 nm.The linear scanning test was taken to the prepared catalysts using rotating disk electrode in O2 saturated 0.5 mol/L H2SO4.When the rotation rate was 1 200 r/min,the oxygen reduction limiting current of MR-CA catalyst was about 4 times higher than melamine-formaldehyde nitrogen contained carbon aerogeK MF-CA) catalyst in the same condition.关键词
