One step to prepare CNTs modified porous g-C3N4 with excellent visible-light photocatalytic performance

Controlled Nucleation and Growth of Carbon Nitride Films on CNT Fiber Fabric for Photoelectrochemical Applications

“…[31] Those properties make the CNT-CN hybrid material very suitable as a photocatalyst for processes such as the degradation of an organic dye, which we evaluated utilizing Rhodamine B as a model for organic pollutant in an aqueous environment. [32] We confirmed the enhanced photocatalytic activity of the hybrid, as well as the photodegradation mechanism (Further details in figure S7, S8). [33] Nevertheless, the obtained CN coating on CNT fibers is very thick and does not allow an easy manipulation as self-standing films, therefore, for the expansion of the CNT-CN hybrids in other energy-related scenarios, and in order to obtain a self-standing material with a better processability we carried out the synthesis of CN films over CNT fibers by chemical vapor deposition (CVD) of melamine (Figure 2a).…”

Boosting photocatalytic H2generation by assembling a copper complex and carbon nanotubes onto a carbon nitride polymer

“…A CNTs/CN hybrid was fabricated according to previous reports. 18,20,50 In detail, 10 g urea and certain amounts of CNTs (0.2, 0.5, 1, 2 mg) were fully dispersed in 50 mL DI water and dried at 80 °C under magnetic stirring. Then, the dried mixtures were annealed in a tubular furnace for 4 h under an argon atmosphere.…”

“…These carbon materials, such as carbon nanotubes (CNTs), are reported as excellent electron receptors with a large work function. [18][19][20] In spite of this, precious platinum nanoparticles are essential cocatalysts for most CN-based photocatalysts. During the H 2 evolution reaction, they could promote the separation of photocharges and decrease the water reduction potential.…”

Structural and chemical approaches to enhance the photo/electrocatalytic performance of carbon/g-C3N4 composite materials

“…The 0D carbon materials are often loaded on the surface of g-C 3 N 4 16,36 while 1D carbon materials are often covered by g-C 3 N 4 . 10 2D carbon materials integrated with g-C 3 N 4 usually cover each other to form a “sandwich”-like structure. 59,63 Although the 2D/2D contact structure of CCNCS benefits the formation of π-conjugated electric field at the local plane, the electric modification exists only at the edges of the interfacial contact.…”

“…[6][7][8][9] However, pristine g-C 3 N 4 exhibits relatively limited catalytic performance, contrary to the expectations, because of its fast recombination rate of photogenerated electron-hole pairs, lack of the ability to adsorb the optic irradiation above 460 nm, poor electrical conductivity (o10 À2 S cm À1 ) and small specific surface area. 10,11 Therefore, the modification of g-C 3 N 4 to improve its catalytic performance and expand its applications has attracted great attention in recent years.…”
