“…However, the peaks at 3440, 2930, 2855, 1628, 1210, and 650 cm –1 could be observed when CSs were analyzed by FTIR. The peak at 3440 cm –1 was ascribed to the −OH stretching vibration, while the peaks at 2930 and 2855 cm –1 were attributed to the antisymmetric and symmetric stretching vibrations of C–H . The peaks at 1628, 1210, and 650 cm –1 were regarded as the stretching vibration of CO, , the stretching vibration band of C–O–C, and the vibration of aromatic C–H, respectively. , When CSs were assembled inside HCS, oxygen-containing functional groups in CS were introduced into HCS, and the intensities of CO and C–O–C peaks in C 0.1 @HCS were obviously promoted.…”

In this paper, a new porous carbon material adsorbent was prepared using carbon microspheres assembled in hollow carbon spheres (HCS) with a hydrothermal method. Transmission electron microscopy, scanning electron microscopy, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, X-ray diffraction, and Raman spectroscopy were used to characterize the adsorbents. It was found that the diameter of carbon microspheres derived from 0.1 mol/L glucose was about 130 nm, which could be inserted inside HCS (pore size was 370−450 nm). The increase in glucose concentration would promote the diameter of carbon microspheres (CSs), and coarse CSs could not be loaded in the mesopores or macropores of HCS. Thus, the C 0.1 @HCS adsorbent had the highest Brunauer−Emmett−Teller surface area (1945 m 2 /g) and total pore volume (1.627 cm 3 /g). At the same time, C 0.1 @HCS posed a suitable ratio of micropores and mesopores, which could provide adsorption sites and volatile organic compound diffusion channels. Moreover, oxygen-containing functional groups −OH and C�O in CSs were also introduced into HCS, and the adsorption capacity and regenerability performance of the adsorbents were improved. The dynamic adsorption capacity of C 0.1 @HCS for toluene reached 813 mg/g, and the Bangham model was more suitable for describing the toluene adsorption process. The adsorption capacity was stably kept above 770 mg/g after eight adsorption−desorption cycles.
