Synthesis and Characterization of Nickel-Based Catalysts

Chloride hexahydrate (NiCl₂·6H₂O), Boric acid (H₃BO₃), ammonium chloride (NH₄Cl), potassium phosphate dibasic anhydrous (K₂HPO₄), Potassium dihydrogen phosphate (KH₂PO₄), Potassium hydroxide (KOH) and polyvinylpyrrolidone (PVP), 25% ammonia (NH₃·H₂O) were bought from Aladdin, and concentrated sulfuric acid (H₂SO₄), copper sulfate pentahydrate (CuSO₄·5H₂O), concentrated nitric acid (HNO₃), ethylenediaminetetraacetic acid, potassium thiocyanate acid (KSCN) and ultrapure water (>18.2 MΩ) were purchased from China National Medicines Corporation Ltd. Ruthenium chloride hydrate (RuCl₃·xH₂O) was obtained from Beijing Innochem Technology Corporation Ltd. All the chemicals were used as received without any other 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.
