Then, 1.28 g of NaOH (Loba Chemie Pvt Ltd, >98%) was dissolved in 10 mL of DDW and added drop-wise to the above solution. After that, the mixture was transferred to a 100 mL Teflon-lined autoclave and heated at 160 °C for 12 h in an electric furnace. The nanoparticles were collected using a permanent neodymium magnet (TM-30 × 50-N magnet, magnets4you Co., Germany), washed three times with DDW to remove inorganic byproducts, and twice with ethanol to remove organic byproducts. Finally, the nanoparticles were dried in an oven at 60 °C for 12 h under vacuum conditions.

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.
