SEC series catalyst
SEC series catalysts are self-developed products of hydrogen energy, including the first generation of SEC100 platinum carbon catalyst and the second generation of SEC200 low platinum catalyst with core-shell structure. The SYNTHESIS PROCESS of SEC SERIES CATALYSTS HAS strict and precise control, the metal particles are evenly distributed on the carbon support, and the noble metal content tolerance is less than or equal to SH1%.
