小弟是做催化的,最近看了一篇文章里面用g-C3N4做載體來催化的,也想試試,可是沒有人對這個了解,實驗室也沒有師兄師姐做過,所以上來求助大神了,我看的文獻里面是用這個方法做得,不知道合成起來容易嗎,或者有什么更好的方法嗎!謝謝了! 5 g of cyanamide was dissolved in 7.5 g of Ludox HS40 solution (dispersion of 12-nm SiO2 particles with 40 wt% in water) and heated at 65 °C overnight to remove water. The as-formed white powder was heated at a temperature of 550 °C for 4 h (ramp: 2 °C min–1) under the protection of N2. The resulting brown-yellow powder was grinded and treated with a 4 M HF acid for 24 h to remove the silica template. The powders were then filtered and washed twice with distilled water and once with ethanol. Finally the powders were dried at 60 °C overnight. |
