“…This might be due to insufficient reaction of the ZnCl 2 with the samples . The GAC-700 samples have a higher graphitization degree than the GAC-pure sample because of proper carbon layer rearrangement caused by exothermic ZnCl 2 modification. , Increased crystallinity appears to reduce communication pathways such as interconnected porosity for the transport of gas molecules, thereby reducing the gas uptake. Moreover, as can be seen, the absence of any sharp peak indicates that no leftover inorganic residues remained in the samples after acid pickling and alkaline washing …”

A volumetric system was used to assess carbon-based adsorbents for evaluation of the gas separation, equilibrium, and kinetics of oxygen (O 2 ), nitrogen (N 2 ), and carbon dioxide (CO 2 ) adsorption on granular activated carbon (GAC) and functionalized GAC at 298, 308, and 318 K under pressures up to 10 bar. The effects of ZnCl 2 , pH, arrangement of the pores, and heat-treatment temperature on the adsorptive capabilities of O 2 , N 2 , and CO 2 were evaluated. High-performance O 2 adsorption resulted with a fine sample (GAC-10-500) generated with a 0.1 wt % loading of ZnCl 2 . The optimal sample structure and morphology were characterized by field-emission scanning electron microscopy, Fourier transform infrared spectroscopy, and powder X-ray diffraction. On the basis of the adsorption–desorption results, the fine GAC provides a surface area of 719 m 2 /g. Moreover, it possessed an average pore diameter of 1.69 nm and a micropore volume of 0.27 m 3 /g. At 298 K, the adsorption capacity of the GAC-10-500 adsorbent improved by 19.75% for O 2 but was not significantly increased for N 2 and CO 2 . Isotherm and kinetic adsorption models were applied to select the model best matching the studied O 2 , N 2 , and CO 2 gas uptake on GAC-10-500 adsorbent. At 298 K and 10 bar, the sip isotherm model with the highest potential adsorption difference sequence and gas adsorption difference compared with pure GAC adsorbent as O 2 > N 2 > CO 2 follows well for GAC-10-500. Eventually, the optimal sample is more effective for O 2 adsorption than other gases.

“…The template-assisted method is also one of the most commonly used strategy for morphology design and preparation. [124][125][126] The 1D template as growth matrix can maintain the dimension of material by sacrificing or retaining templates, whose choice is the key of study. For example, Zheng and co-workers [127] selected biomass fibro bacteria as growth matrix to load Ti 2 Nb 10 O 29 .…”

In various energy storage devices, the development and research of electrode materials has always been a key factor. Nb‐based materials are one choice of energy storage materials because of the good ion‐diffusion channels and high theoretical capacity. More importantly, their advantages, such as safe potential range, high structural stability, and highly reversible redox reaction with small strain, are conducive to efficient, safe, and stable energy storage development. Based on aforementioned superiority, much of the research is to further optimize performance of Nb‐based materials by unique nano‐morphology design, lattice regulation, and functional additives composition, showing good electrochemical performance in many kinds of devices. This review mainly introduces the classification of Nb‐based materials used for energy storage, their application in different battery systems, and common optimization methods. Accordingly, the deficiencies and prospects of Nb‐based materials are also discussed in detail.
