“…As guided by the predicted results of MO/C coordinated structure, CNT‐O@M SACs was successfully synthesized by our developed sequential flame‐assisted method. In this synthetic process, O doped CNT (CNT‐O) was constructed on metal matrix first by modified flame‐assisted method [ 32–35 ] and then metal atoms were immobilized on CNT‐O via strongly coordination with oxygen during second flame‐assisted treatment ( Figure a and Figure S2, Supporting Information). During roasting process, the inner flame of alcohol lamp releases much carbonaceous molecules, which are not fully burned and can be used as carbon source for the growth of CNT.…”

Single‐atom catalysts (SACs) exhibit intriguing performance in electrocatalysis owing to their maximized atom utilizations and unique electronic structures, but effective anchoring metal atoms with defined coordination structure on hierarchical integrated electrode remain a challenge. Herein, a fast and facial flame‐assisted strategy is developed to construct oxygen‐coordinated SACs on integrated carbon nanotube (CNT) arrays with promising applications in electrocatalysis. Density functional theory calculations show that oxygen in carbon substrate imparts homogeneous sites for the efficient anchoring of metal atoms, thereby enabling SACs to disperse uniformly and firmly and thus bringing optimized activities. Moreover, the integrated CNT array with abundant oxygen‐containing groups is constructed and has been used as an efficient matrix for anchoring metal atoms (CNT‐O@M) via a flame‐assisted method. The as‐prepared CNT‐O@M (M = Co and Pt as typical examples) shows excellent activities in electrocatalytic oxygen reduction reaction and hydrogen evolution reaction with utilization of active site as high as 75.7%, which is superior to the reported SACs. Particularly, the performance of CNT‐O@M can maintain stably under various harsh conditions, showing a promising prospect in the long‐time applications. The methodology and concept proposed in this work could be extended to the synthesis of a variety of integrated SACs for efficient electrocatalysis.

The helical structures possess unique physical and chemical properties, such as superelasticity, high specific strength, chirality, and electromagnetic cross-polarization characteristics. With the development of nanoscience and nanotechnology, helical structures with various scales have been discovered or synthesized artificially. Among them, the helical carbon materials receive much attention around the world. Herein, we present a brief review of the development of helical carbon materials in terms of structures, synthesis techniques and mechanisms, and applications. The controllable designing of catalysts, carbon sources and reaction parameters plays a key role to optimize the properties of the helical carbon materials. At the same time, the applications in microwave absorption devices, sensors, catalysts, energy conversions and storage devices, and solar cell are also presented. For the good chemical and physical properties, helical carbon materials have a good application prospect in many fields. The potential issues and future opportunities of the helical carbon materials are also proposed.

Through resistance welding experiments, the effects of process parameters and heating elements (HE) on the welding strength of carbon fiber reinforced polyamide 6 (CF/PA6) composites were studied. Stainless steel mesh was used as the heating element for welding CF/PA6 composites. The mechanical properties of the weld were tested using a universal testing machine, and the internal structure and fracture of the joint were analyzed by scanning electron microscopy (SEM). The optimal parameters for welding CF/PA6 composites were determined. In addition, the growth of carbon nanotubes (CNTs) on the surface of the metal mesh significantly improved the welding strength, from 14.016 to 16.31 MPa. The experimental results showed that the optimal parameters included 22A current, 0.3 MPa pressure and 35 s welding time, and the optimal specification of the metal mesh heating element was 200 mesh. The burning time of the metal mesh was 10 s, and the optimum pickling time was 30 s.Highlights The matrix of the composite material is nylon 6. Improved the experimental process for growing carbon nanotubes. Explore the influence of burning time on welding effect through detection.
