TEM results and XRD results indicated that the Pt microparticles were uniformly high dispersed on nanoTiO2-CNT films, nanoTiO2-CNT decreased catalytic agglomeration rate, and these made the Ti/nanoTiO2-CNT samples higher specific surface area of Pt.

• 第一部分:采用循环伏安(CV)共沉积方法制备出高分散的Ti/nanoTiO_2-CNT-Pt催化剂,利用循环伏安电化学方法评价了该电极催化剂对甲醇的电催化活性和稳定性。
