Chemical Vapor Deposition Synthesis of 3D Hybrid Carbon Materials at Low Pressure and Temperature

A novel low-temperature method to synthesize a hybrid carbon material (HCM) is reported. The synthesis relies on a chemical vapor deposition (CVD) approach, using zeolite NaY as a scaffold structure and acetone as the carbon source. The deposition temperature was 500 °C at a pressure of 46 ± 1 kPa. Following the growth of the HCM, the material was treated with HF to remove the scaffold, and the resultant materials were characterized by high-resolution scanning electron microscopy (HR-SEM), energy-dispersive X-ray spectroscopy (EDS) mapping, transmission electron microscopy (TEM), X-ray diffraction (XRD), Raman microscopy, and Brunauer-Emmett-Teller (BET) surface area analysis, showing heterogeneous morphology. The results demonstrate that synthesis at low temperatures produces a robust hybrid material that can adopt different configurations and/or morphologies by modifying the scaffold structure.
