Abstract: 
28platinum/carbon catalyst%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>2f4a8b>platinum/carbon catalyst is one of the most important catalysts in 28hydrogenation%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>2f4a8b>hydrogenation of 28ortho-nitrochlorobenzene%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>2f4a8b>ortho-nitrochlorobenzene to 2,2-dichlorohydrazobenzene. The preparation process and the supports of catalysts are studied in this paper. Raw materials and preparation procedure of the activated carbon have great influences on the compositions and surface structure of 28platinum/carbon catalyst%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>2f4a8b>platinum/carbon catalysts. Platinum catalysts supported on activated carbon with high purity, high surface area, large pore volume and appropriate pore structure usually exhibit higher activities for 28hydrogenation%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>2f4a8b>hydrogenation of 28ortho-nitrochlorobenzene%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>2f4a8b>ortho-nitrochlorobenzene to 2,2-dichlorohydrazobenzene. The catalyst prepared from H2PtCl6 with pH=3 shows greater catalytic performance than those prepared under other conditions.
