The applications of many energy-related electrochemical energy conversion and storage devices are changing with each passing day. Oxygen evolution reaction (OER), hydrogen evolution reaction (HER) and oxygen reduction reaction (ORR) are the key steps in the commercial application of these energy conversion/storage equipment. Defect-rich transition metal oxides (TMOs), such as Co, Mn, Fe, Ni, etc., have always been one of the most promising electrocatalysts, which are cheap, easy to obtain, high in catalytic activity and stable during electrocatalysis. In this review, we first introduce the definition, classification, characteristics, and construction of defects. Then, the latest developments of defect-rich TMO electrocatalysts in electro-catalysis and energy conversion storage device is summarized. Furthermore, the relationship between defects and activity and the potential mechanism are also discussed. The defects in defect-rich TMOs can adjust the surface/interface electronic structure of the electrocatalyst, change the adsorption energy of the intermediate product, or increase the intrinsic catalytic activity of active sites, which are beneficial for enhanced catalytic performance. Finally, the current challenges and prospects of defect-rich TMO electrocatalysts are proposed. Therefore, the introduction of defects in TMO will be a potential strategy for the rational design of high-performance electrocatalysts in the future.

The performance of durability in direct methanol fuel cell (DMFC) is of great significance. In this study, NiCo 2 O 4 with three-dimensional ordered hierarchical pore was applied as oxygen reduction reaction electrocatalyst to enhance the longterm stability in passive DMFC. The peak power densities of NiCo 2 O 4 -based DMFC were 14.78 and 26 mW cm À 2 at 15 and 40°C, respectively. In the durability test, NiCo 2 O 4 -based DMFC could operate continually for 1406 hours, which is approx-imately 6 times higher than the highest values reported in literature. And the outstanding durability could be mainly ascribed to the interconnected and ordered macropores channel in NiCo 2 O 4 , which could act as a structural buffer to mitigate the structural changes in porous nano-catalysts, and also significantly facilitate the mass transport and the rapid elimination of cathodic product to solve the problem of "water flooding" at the cathode.
