Abstract:

This work provides a simple but efficient strategy for the adjustment of texture and regular morphology of graphitic carbon nitride (CN) material by the post-synthesis of successive heat-vacuum treatment (SHVT) method without using hard templates. The modified CN displayed various hollow microtubule structure and the improvement of s-heptazine unit depending on the SHVT temperature. The best hollow microtubule morphology with highest contents of the key s-heptazine structure can be achieved by SHVT at 540 °C. These modified CN samples led to the highest photocatalytic H2 yield of 1160 μL for 4 h reaction under visible light irradiation, which is almost 10 times higher than that of the traditional CN (118 μL). The results represent an alternative approach to preparing hollow microtubule morphology and improving the s-heptazine structure in CN for enhancing photocatalytic performance. © 2016 Elsevier Ltd
