Activated carbon samples were synthesized by chemical and physical activations of tangerine peel. The activated carbons were characterized via using Fourier Transform Infrared-Attenuated Total Reflectance spectroscopy (FTIR-ATR), Scanning Electron Microscopy (SEM), Brunauer-Emmett-Teller (BET), Differential Thermal Analysis-Thermogravimetry (DTA/TG) techniques. It was found that the activated carbon samples were porous, and their surface areas were increased by treating with the various concentrations of ZnCl₂ and KOH. After the formation of activated carbons, they turned into a structure that was formed from carbon atoms, and their residual amounts decreased. In addition, the hydrogen storage capacities of the activated carbon samples were measured in different pressures at 77 and 298 K using the Hiden IMI PSI instrument. The results, confirmed that the hydrogen storage capacities of the activated carbons were higher at the cryogenic temperatures, and higher hydrogen storage capacity were observed by the increasing concentrations of activation agents in the synthesized activated carbons. The activated carbons synthesized by ZnCl₂ had higher hydrogen storage capacity than those by KOH.

通过橘皮的化学和物理活化合成了活性炭样品。通过使用傅里叶变换红外衰减全反射光谱（FTIR-ATR），扫描电子显微镜（SEM），Brunauer-Emmett-Teller（BET），差示热分析-热重分析（DTA / TG）技术对活性炭进行表征。发现活性炭样品是多孔的，并且通过用不同浓度的ZnCl ₂处理而增加了它们的表面积。和KOH。活性炭形成后，它们变成了由碳原子形成的结构，残留量减少了。此外，使用Hiden IMI PSI仪器在77和298 K的不同压力下测量了活性炭样品的储氢能力。结果证实，在低温下活性炭的储氢能力更高，并且通过合成的活性炭中活性剂浓度的增加观察到更高的储氢能力。ZnCl ₂合成的活性炭具有比KOH更高的储氢能力。
