Combined synthesis and hydroprocessing on a cobalt catalyst on a cobalt-containing zeolite catalyst
A composite Co-Al2O3/SiO2/HZSM-5 catalyst has been developed for one-step synthesis of fuel series hydrocarbons from CO and H2. The catalyst was obtained by mixing and forming powders with a Co-Al2O3/SiO2 catalyst, zeolite HZSM-5, and boehmite Al(O)OH?H2O.

The genesis of supported cobalt catalysts [PDF]
The general objectives of this research were to investigate the effect of the support and the gas atmosphere on the decomposition and reduction of cobalt nitrate hexahydrate supported on silica and alumina to gain a greater understanding of the calcination and reduction procedures used in catalyst manufacturing processes. The decomposition was followed

Balancing Electrons to Break the Activity‐Selectivity Trade‐Off in H2O2 Electrosynthesis
Carrier‐concentration balancing in CuS is achieved by coupling cobalt dopants with cobalt vacancies, converting CuS from p‐ to n‐type to accelerate 2e− ORR while withdrawing excess carriers to optimize *OOH binding for H2O2 desorption. The catalyst reaches 8.14 mol g−1 h−1 with >84% selectivity in 1.0 M KOH and drives robust electro‐Fenton dye ...
