LSCD-B Catalyst of diphenylamine is synthesized using nanocrystalline siallitic oxide and nano-fibers as raw staff. The technical parameter of catalyst of LSCD-B is more excellent than LSCD-A, such as surface area, pore distribution and pore size so on. The performance parameter of LSCD-B is shown as follow.
