摘　　要：采用溶胶-凝胶法制备了Co-Mo二元硫化物阳极催化剂。通过TG、SEM对催化剂进行表征,测定催化剂在1000℃以下时的电导率;通过比较催化剂在反应前后的红外光谱图,评价催化剂的耐硫性能。结果表明:Co-Mo阳极催化剂具较好的热稳定性,较大的孔隙率和电导率,以及优越的耐硫性能,满足固体氧化物燃料电池阳极催化剂的要求,是一种新型的耐硫阳极材料。The anode catalyst, binary sulfide of Co-Mo, was prepared by sol-gel method. The properties of catalyst were characterized by TG, SEM, et al. The conductivity of catalyst was measured under 1000℃. The IR pattern of catalyst before reaction was compared with IR pattern after reaction, in order to value the performance of sulfur tolerance. The results showed that the anode catalyst with good heat-stability had high conductivity. The performance of sulfur tolerance was fine, which satisfied the anode catalyst of solid oxid fuel cell. The binary sulfide of Co-Mo is a new kind of anode catalyst with sulfur tolerance.
