Edge-differentiating deposition of Co on SiO2-supported MoS2 particles

The chemical vapor deposition of Co(CO)(3)NO under controlled conditions onto MoS2 catalysts supported on SiO2 achieves the edge-differentiating deposition of Co between (10 (1) over bar0) and ((1) over bar 010) edges of MoS2 particles, the former edge being preferentially decorated by Co at a low Co content to form a catalytically active'' structure for hydrodesulfurization.
