Synthesis of Fe-doped g-C3N4 Nanosheets

Check if the same lab product or an alternative is used in the 5 most similar protocols
To synthesize Fe-doped g-C3N4, 0.5 g of g-C3N4 nanosheets was dispersed in 50 mL of distilled water by magnetically stirring for 30 min and then ultrasonicating for 1 h to obtain a suspension of g-C3N4 nanosheets. An appropriate amount of ferric chloride hexahydrate (FeCl3.6H2O, >98%, Sigma-Aldrich, China) corresponding to 3, 5, 7, 8, 10 mol% of Fe was added to above solution which was continuously heated for 12 h at temperature of 90 °C under magnetically stirring condition in order to allow Fe atoms to insert into appropriate interstitial positions in g-C3N4 crystal lattice. The suspension was rinsed with ethanol and centrifuged at 6000 rpm for 10 min for 3 times to remove excess contaminations from the solution. The remaining material was dried at 80 °C for 5 h to achieve Fe-doped g-C3N4 nanosheets.
For a convenient, g-C3N4 photocatalysts doped with 3, 5, 6, 7, 8 and 10 mol% of Fe were denoted as FeCN3, FeCN5, FeCN6, FeCN7, FeCN8 and FeCN10, respectively.

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.
