摘　　要：选用新型纳米材料——碳纳米管(CNTs)作为催化剂载体,用沉积沉淀法制备负载型钯-铂合金催化剂。同时选用过渡金属碳化物材料(碳化钨)为催化剂,其具有类似于Pt的表面电子结构,有望替代贵金属催化剂。探讨了Pd-Pt/CNTs及碳化钨在氢氧直接合成过氧化氢反应中的催化性能。Carbon nanotubes were used as the supports for preparation of Pd-Pt alloy catalysts for direct synthesis of hydrogen peroxide by deposition-precipitation method. Tungsten carbide （WC） was also used as the catalyst for direct synthesis of hydrogen peroxide as a substitute for noble metal catalysts due to their similarity in surface electronic structure. The catalytic behaviors of WC and Pd-Pt/carbon nanotbubes （CNTs） in direct synthesis of hydrogen peroxide were investigated.
