Special Issue Information

Dear Colleagues,

Carbon-based nanomaterial catalysts show unique advantages in a variety of catalytic reactions, especially in environmental governance and energy conversion. Due to their excellent chemical stability, adjustable surface properties and abundant carbon vacancies, they have become advanced materials in the field of catalysis. In recent years, researchers have further improved the catalytic performance of carbon-based materials—such as graphene, carbon nanotubes, carbon quantum dots and carbon nanofibers—by combining them with other functionalized nanomaterials. This has enabled them to form various carbon-based composite catalysts, which are widely used in photocatalysis, electrocatalysis, enzyme catalysis, biomass catalysis and other fields.

Carbon-based nanomaterial catalysts also show significant advantages in environmental pollution control, especially in the adsorption and degradation of organic pollutants and in the reduction and solidification of heavy metal ions. The high adsorption capacity and photocatalytic activity of these materials make them an ideal choice for a clean environment. With the continuous development of synthesis methods and structure optimization technologies, the catalytic performance of carbon-based nanomaterial catalysts is expected to be further improved, contributing to the sustainable development of clean energy and a clean environment.

Developing a catalyst with excellent electrical conductivity and catalytic performance for on-site testing of residual imidacloprid is significant and challenging. In situ growth of Mo2C nanodots on Co-induced N-doped carbon nanotubes (Co/Mo2C/N-CNT) was synthesized to construct a molecularly imprinted electrochemical sensor for the detection of imidacloprid. The results proved that the catalytic performance of Co/Mo2C/N-CNT for imidacloprid was over two times higher than those of Co/N-CNT and commercial CNT. This improvement was attributed to the formation of a heterostructure between Co species, Mo2C, and N-CNT, which facilitated highly exposed catalytic active sites. Additionally, the abundant Mo2C nano-dots promoted interfacial charge transfer to achieve optimal dynamics. The optimum preparation parameters of the catalysts were obtained by response surface methodology. By analyzing the relationship between different pH values and peak potential, as well as the influence of different scanning rates on peak potential, it was deduced that the possible electrocatalytic mechanism of imidacloprid involved the reduction of the nitro group to a hydroxylamine group and H2O. Under optimal conditions, the limit of detection (LOD) was 0.033 × 10−6 mol·L−1 (R2 = 0.99698), and the linear range was 0.1 × 10−6~100 × 10−6 mol·L−1. The application effect of the prepared sensor was evaluated by measuring the imidacloprid in two kinds of tea, indicating that the sensor possessed good sensitivity and selectivity, and was capable of meeting the requirements of on-site detection.
