“…The more intense peaks corresponding to carbonate species in the spectrum of MgO-LPT suggest that MgO-LPT possesses more active sites, leading to high CO2 uptake capacity. The sharp peak at 550 cm −1 observed for MgO-TD and the strong peak at 460 cm −1 obtained for MgO-LPT corresponds to the stretching vibration of Mg-O [20,21].…”

The utilization of the lime (Citrus aurantifolia) peel as a template can improve the adsorbent’s structural properties, which consequently affect its CO2 uptake capacity. Herein, a mesoporous magnesium oxide (MgO-lime (Citrus aurantifolia) peel template (LPT)) adsorbent was synthesized using an LPT. MgO-LPT demonstrated improved structural properties and excellent CO2 uptake capacity. Moreover, another MgO adsorbent was prepared via thermal decomposition (MgO-TD) for comparison. The prepared adsorbents were characterized by N2 physisorption, Fourier transform infrared spectroscopy and thermogravimetric analysis. The CO2 uptake of these adsorbents was under 100% CO2 gas and ambient temperature and pressure conditions. MgO-LPT exhibited a higher Brunauer–Emmett–Teller surface area, Barrett–Joyner–Halenda pore volume, and pore diameter of 23 m2.g−1, 0.142 cm3.g−1, and 24.6 nm, respectively, than those of MgO-TD, which indicated the mesoporous structure of MgO-LPT. The CO2 uptake capacity of MgO-LPT is 3.79 mmol CO2.g−1, which is 15 times that of MgO-TD. This study shows that the application of lime peel as a template for the synthesis of MgO adsorbents is a promising approach to achieve MgO adsorbents with enhanced surface area and thus increased CO2 capture performance.

In the past two and a half decades, there has been rapid growth in the study of electrochemical supercapacitors. Zinc oxide based electrode materials are proposed for supercapacitor applications because of their less price, ecofriendliness, good electrochemical reversibility, more specific capacitance, etc. In this research work, a set of nanohybrid electrode materials with a composition of Zn 1-x Mg x O 1-δ (where x = 0.1, 0.2, 0.3 and 0.4) has been prepared by a simple chemical precipitation technique. The prepared electrode materials were analyzed by XRD, FTIR, SEM and EDAX. Electrochemical studies, such as cyclic voltammetry, galvanostatic charge-discharge and impedance analysis were carried out in an aqueous electrolyte (1 molL -1 Na 2 SO 4 ) to understand the electrochemical characteristics of the Mg-doped ZnO nanohybrid materials. The findings show that the doping level of Mg in ZnO had an important role in understanding the capacitive behaviors of the materials. Among the four-electrode materials studied, Zn 0.90 Mg 0.10 O 1-δ electrode material exhibits a maximum specific capacitance of 26.33 Fg -1 at a scan rate of 10 mV and hence which may be suitable for electrochemical supercapacitor applications.

The purpose of this study was synthesizing mesoporous silica SBA-15 and investigated the effect of the initial temperature of the preparation surfactant using the hydrothermal process to synthesize silica SBA-15. Pluronic (P123) as surfactant template and TEOS as material precursor acted as a building block of the mesoporous silica material. Therefore, the interaction surfactant template and precursor during the hydrothermal process guided to silica SBA-15 properties. The results suggested that the physicochemical properties of these materials did not change significantly, but different condition temperature of surfactant and hydrothermal process affected the size of the specific surface area, pore volume, and pore size distribution. The largest specific surface area was 560 m 2 g -1 , pore volume was 1.57 m 3 g -1 and ordered pore size distribution around 11.24 nm after the initial temperature of the surfactant at 15 o C and hydrothermal process at 100 o C for 48 h. This resulted properties of SBA-15 are potentially applicable in various chemical and non-chemical based industries.
