In this work, 16 MeV, 3 μm Si~(5 ) beam is used to perform the micro-ERDA analysis to study the hydrogen kinetics in titanium. The hydrogen is found to distribute in titanium inhomogenously. Hydrogen retention and concentration are strongly related to the chemical and physical state of the hydrogen atom, which affect to the titanium surface-corrosion and hydrogenation process.

8.With the optimized catalyst of Pd-Co/C, the kinetic experiments were carried out, and the macroscopic kinetics equation was obtained as follow:It was found that object reaction is 0 order reaction as for the concentration of 3,5-dihydroxybenzoic acid, and 1 order for that of hydrogen donor of sodium format and that of the related catalyst.
