The development of a catalyst that is both effective and robust is desirable, but remains a challenge for those aiming to commercialize polymer electrolyte membrane fuel cells. Thus, a facile method is proposed to develop hierarchical and three-dimensional titanium nitride (TiN) architectures, with the robust non‑carbon material being implemented as the Pt support. The resulting catalyst (Pt/TiN) demonstrates high activity and stability, and the experimental data confirm the critical significance of the novel TiN support.

多孔和三维氮化钛负载铂作为氧还原反应的电催化剂

期望开发既有效又坚固的催化剂，但是对于那些旨在商业化聚合物电解质膜燃料电池的催化剂而言仍然是挑战。因此，提出了一种简便的方法来开发分层和三维的氮化钛（TiN）体系结构，并使用坚固的非碳材料作为Pt支撑。所得催化剂（Pt / TiN）表现出高活性和稳定性，并且实验数据证实了新型TiN载体的关键意义。
