功能化碳材料具有多功能性和环境友好性，在实际应用中显示出巨大的潜力，特别是在能源转换方面。开发具有可以通过简单地改变原始材料的比例来调节的性能的碳复合材料是一种有趣的合成策略。本文以氨基氰和多壁碳纳米管为前驱体，采用一种简便的方法制备了一系列石墨碳氮化物/碳纳米管（g-C3 N4/CNTs）复合材料。这些复合材料表现出不同的实际应用与不同的组分的重量比，即，它们表现出协同效应，在光电转换时，g-C3 N4的主要成分和氧还原反应（ORR）时，碳纳米管占主导地位的复合材料。实验表明，碳纳米管的高导电性促进了电荷在两种情况下的传输。
Due to their versatile features and environmental friendliness, functionalized carbon materials show great potential in practical applications, especially in energy conversion. Developing carbon composites with properties that can be modulated by simply changing the ratio of the original materials is an intriguing synthetic strategy. Here, we took cyanamide and multiwalled carbon nanotubes as precursors and introduced a facile method to fabricate a series of graphitic carbon nitride/carbon nanotubes (g‐C3N4/CNTs) composites. These composites demonstrated different practical applications with different weight ratios of the components, that is, they showed synergistic effects in optoelectronic conversion when g‐C3N4was the main ingredient and in oxygen reduction reaction (ORR) when CNTs dominated the composites. Our experiments indicated that the high electrical conductivity of carbon nanotubes promoted the transmission of the charges in both cases.
