摘要：

Amorphous MoS3 particles are prepared using a simple chemical method. Several deposition techniques are developed to fabricate electrodes loaded with MoS3 particles. These electrodes are highly active for hydrogen evolution. The catalytically active species appear to be reduced molybdenum sulfide that contains disulfide ligands. The MoS3 particles are annealed to form polycrystalline and single crystalline MoS3 and MoS2 particles. These particles, as well as commercial MoS2 micro-crystals, show inferior catalytic activity compared to the amorphous MoS3 particles.
