Cheers for titania: An N-doped composite of carbon nanotubes (CNTs) and mesoporous TiO(2) is used as support for Pt nanoparticles applied in the oxygen reduction reaction. The composite Pt/N-TiO(2) -CNT shows a higher stability than Pt particles on carbon black or N-doped CNTs, as indicated by accelerated stress tests of up to 2000 cycles. The enhanced stability is attributed to strong interactions between TiO(2) and Pt and a higher corrosion resistance of TiO(2) as well as CNTs.
将碳纳米管（CNT）和介孔 TiO(2) 的 N 掺杂复合材料用作负载 Pt 纳米粒子的载体，用于氧还原反应。复合 Pt/N-TiO(2)-CNT 比负载在碳黑或 N 掺杂 CNT 上的 Pt 颗粒具有更高的稳定性，这可通过高达 2000 次循环的加速压力测试来证明。稳定性的提高归因于 TiO(2) 和 Pt 之间的强相互作用以及 TiO(2) 和 CNTs 的更高耐腐蚀性。
