Accordingly, we propose that the deficiency in Cu and enrichment in Mo of the porphyry deposits in the Zhangguangcai-Lesser Xing'an range most likely formed due to mantle-derived magmas interacting with reduced crustal materials or melts in the deep crust. This resulted in substantial sequestration of Cu and S, decreasing porphyry Cu …

Molybdenum catalyzed commercial processes for instance, hydrotreating (the catalyst: Co-Mo oxides or Ni-Mo oxides on alumina), formaldehyde manufacture (the catalyst: Fe-Mo catalyst) do pose a typical solid waste disposal problem. In order to recycle the catalytic element, it is always desirable to treat the so-called spent catalysts.

The as-prepared magnetic Fe3O4/GO/MoS2 nanocomposite exhibited good enrichment capability toward fluoroquinolone antibiotics and the analytes were absorbed within a short time ca. 2 min. The main drive forces of Fe3O4/GO/MoS2 nanocomposite and antibiotics were most likely attributed to hydrogen bonding and electrostatic attraction.
