Escalating both electrochemically active and stable materials at a time is an important challenge in the field of catalysis till to date. Carbon as a pillar material has been used for long time due to its intrinsic properties like high conductivity and large surface area that can increase activity of electrocatalyst. However, severe drop in activity due to carbon corrosion is the main challenge. Here, we introduce robust, conductive and stable Magnéli phase Ti₄O₇ nano-pillar in to flower like nickel ruthenium-layered double hydroxide (3D-FL-NiRu-LDH/ Ti₄O₇) through an easy in situ growth approach for the first time. The decoration of Magnéli phase Ti₄O₇ not only significantly improves the activity but also stability of LDH nanosheet catalyst. The as-synthesized materials retain 98% of the activity after 45 h which surpasses all the reported LDH catalysts for oxygen reduction reaction under alkaline media. The key roles of Ti₄O₇ are to provide the effective charge transfer networks of LDH catalyst and prevent agglomeration of LDH catalysts though strongly coupled interactions evidenced by X-ray photoelectron spectroscopy (XPS). Therefore, the developed catalyst demonstrates promising conductivity, together with durability. The reported approach of introducing a robust and conductive pillar coupled with LDH catalysts provides a novel pathway for developing a highly efficient and durable electrocatalyst.

迄今为止，一次升级电化学活性材料和稳定材料是催化领域中的重要挑战。碳作为支柱材料由于其固有的特性（如高电导率和较大的表面积，可以增加电催化剂的活性）而被长期使用。然而，由于碳腐蚀导致的活性严重下降是主要挑战。在这里，我们通过一种易于原位生长的方法，将坚固，导电且稳定的Magnéli相Ti ₄ O ₇纳米柱引入到像镍钌层状双氢氧化物（3D-FL-NiRu-LDH / Ti ₄ O ₇）一样的花朵中。第一次。Magnéli相Ti ₄ O ₇的装饰不仅显着提高了LDH纳米片催化剂的活性，而且提高了稳定性。合成后的材料在45小时后保留了98％的活性，超过了所有已报道的在碱性介质下进行氧还原反应的LDH催化剂。Ti ₄ O ₇的关键作用是提供X射线光电子能谱（XPS）证实的强耦合相互作用，从而提供LDH催化剂有效的电荷转移网络并防止LDH催化剂团聚。因此，开发的催化剂显示出有希望的电导率以及耐久性。引入结合LDH催化剂的坚固导电柱的报道方法为开发高效耐用的电催化剂提供了一条新颖的途径。
