Abstract
HighlightsMonodisperse nitrogen-doped carbon nanospheres were synthesized and loaded onto graphitic carbon nitride and the composites show outstanding photocatalytic activity.Improved sulfachloropyridazine degradation is consistent with density functional theory calculation..
Highlights
In recent decades, human being has been enjoying the benefits of the technology development more than ever before in the human history
It has been reported that carbon materials as metal-free sustainable catalysts, such as graphene [10], graphene oxide [1, 10], carbon quantum dots [11], carbon nanotubes [12], and carbon nanospheres [9], can effectively promote photocatalytic reactions
From TEM images (Fig. 1e, f), we can see these carbon nanospheres can be immobilized onto GCN, and the size of carbon sphere was 400 nm, which is a suitable size to form strong interaction with GCN as observed previously [32]
Summary
Human being has been enjoying the benefits of the technology development more than ever before in the human history. A variety of protocols involving heteroatom doping [22, 23], morphology modification [3, 24], hybrid copolymerization [25, 26], exfoliation [27] and co-catalysts have been employed to overcome these barriers and enhance the photocatalytic activity. Among these methods, the modification by a carbon material [28] has become a hot focus, because of their potentials for enlarged specific area, good electronic conductivity and excellent rate of electron transfer [29,30,31]. This work provides a facile way to modulate the intrinsic electronic and band structure of GCN and would lead to a simple and effective approach to synthesize an efficient NC/GCN photocatalyst via N-doping
