Characterizations of as-prepared sample. a STEM-EDS mapping images, b Colored STEM image coupled with EDS line scanning (inset) of a single cavity, and c HRTEM image with corresponding Fast Fourier Transform (FFT) pattern and molecular model matched IFFT image of the NiS2@NPCTs/S composite (insets). d XRD patterns of the NPCTs, NiS2@NPCTs/S, and sulfur. e Thermogravimetry (TG) and derivative thermogravimetry (DTG) curves of the NPCTs/S and NiS2@NPCTs/S. High-resolution XPS spectra of f Ni 2p, g S 2p, and h N 1s for NiS2@NPCTs/S composite. i Comparison of C 1s spectrum between NPCTs and NiS2@NPCTs/S composite
