A novel three-dimensional (3D) hybrid consisting of molybdenum disulfide nanosheets (MoS₂) uniformly bound at N-doped macro-mesoporous carbon (N-MMC) surface was fabricated by the solvothermal method. The resulting MoS₂/N-MMC hybrid possesses few-layer MoS₂ nanosheets structure with abundant edges of MoS₂ exposed as active sites for hydrogen evolution reaction (HER), in sharp contrast to large aggregated MoS₂ nanoflowers without N-MMC. The high electric conductivity of N-MMC and an abundance of exposed edges on the MoS₂ nanosheets make the hybrid excellent electrocatalytic performance with a low onset potential of 98 mV, a small Tafel slope of 52 mV/decade, and a current density of 10 mA cm⁻² at the overpotential of 150 mV. Moreover, the MoS₂/N-MMC hybrid exhibits outstanding electrochemical stability and structural integrity owing to the strong bonding between MoS₂ nanosheets and N-MMC.

通过溶剂热法制备了新颖的三维（3D）杂化体，该杂化体由二硫化钼纳米片（MoS ₂）均匀地结合在掺氮的大中孔碳（N-MMC）表面上。所得的MoS ₂ / N-MMC杂种具有几层MoS ₂纳米片结构，其中大量MoS ₂边缘暴露为氢放出反应（HER）的活性位点，与没有N-MMC的大型聚集MoS ₂纳米花形成鲜明对比。N-MMC的高电导率和MoS ₂上大量的裸露边缘纳米片使杂化材料具有出色的电催化性能，起始电势低至98 mV，Tafel斜率小至52 mV /十年，在150 mV的超电势下电流密度为10 mA cm ^-2。此外，由于MoS ₂纳米片与N-MMC之间的牢固结合，MoS ₂ / N-MMC杂化物表现出出色的电化学稳定性和结构完整性。
