5 protocols using nickel chloride hexahydrate

1

Synthesis of Carbon-Supported Nickel Catalyst

Check if the same lab product or an alternative is used in the 5 most similar protocols
Commercial TiC (dave of 90 µm, 99.8%, Goodfellow) was employed as carbon precursor. Chlorine (purity 2.8, Linde AG) and hydrogen (purity 5.0, Linde AG) diluted by helium (purity 4.6, Linde AG) were used to perform reactive extraction of carbide (chlorination) and subsequent carbon surface annealing. Nickel chloride hexahydrate (99.95% purity, Alfa Aesar) was used as precursor of the Ni catalyst.

Fabrication of Yttrium-Doped Barium Cerate Anode

Check if the same lab product or an alternative is used in the 5 most similar protocols
Yttrium-doped barium cerate powder BaCe0.85Y0.15O2.925 (BCY15), supplied by Marion Technologies, was fabricated by auto-combustion method and applied as the anode ceramic matrix. Before synthesis, the BCY15 powder was thermally pretreated at 1100 °C for 2 h. Nickel chloride hexahydrate (NiCl2·6H2O), hydrazine monohydrate (99+% N2H4·H2O), sodium hydroxide (NaOH), and anhydrous sodium carbonate (Na2CO3) were procured by Alfa Aesar (Ward Hill, MA, USA). Anhydrous (99.8%) ethylene glycol (EG) was acquired by SIGMA-ALDRICH. All reagents were of “pro analyze” purity grade and were used as received without further purification.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
