文摘

We demonstrate mesoporous molybdenum nitride nanobelts as a cathode catalyst synthesized by a topotactic reaction process. The molybdenum nitride nanobelts exhibit a single-crystalline face-centered cubic Mo₂N. Moreover, the molybdenum nitride nanobelts exhibit a mesoporous structure with ~4.3 nm as an average pore size and ~41.9 m² g^鈭? as a specific surface area. The improved electrocatalytic activity of mesoporous molybdenum nitride nanobelts toward oxygen reduction reaction in alkaline solution might be mainly attributed to high specific surface area and mesoporous structure.
