Representative work: Abstract To meet the practical demand of overall water splitting and regenerative metal–air batteries, highly efficient, low‐cost, and durable electrocatalysts for the oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER) are required to displace noble metal catalysts. In this work, a facile solid‐state synthesis strategy is developed to construct the interfacial engineering of W 2 N/WC heterostructures, in which abundant interfaces are formed. Under high temperature (800 °C), volatile CN x species from dicyanodiamide are trapped by WO 3 nanorods, followed by simultaneous nitridation and carbonization, to form W 2 N/WC heterostructure catalys Abstract Recently, molybdenum dioxide (MoO 2 ) has gained intensive attention as an eco‐friendly and earth abundant catalyst for electrocatalytic hydrogen evolution from water splitting. However, the catalytic activity of MoO 2 catalyst for hydrogen evolution reaction (HER) is severely limited by the less exposed active sites. Herein, we present Co‐doped MoO 2 for efficient HER through a facile wet chemistry synthesis followed by calcination treatment process. The optimized Co‐MoO 2 ‐0.01 nanorods (NRs) delivers a very low overpotential of 26 mV at 10 mA cm −2 and a small Tafel slope of 30.9 mV dec −1 , which is much better than that of pure MoO 2 NRs and the commercial Pt/C catalyst in HER.
