“…The existence of these pores in the lignin fibers during the carbonization process by the removal of volatile material enhances its structural properties [29]. Type IV isotherm is also shown by various biomass like cassava peel [39] and banana stem fibers [40]. It has been proposed that the shape of the hysteresis loop and the texture (pore size and pore geometry) of porous materials are related.…”

Uranium (as a hazardous and radioactive element) removal from wastewater requires reliable technology and proper functional materials. Carbon fiber species that are produced from agricultural solid waste can be a proper type of low-cost adsorbents for wide uses in wastewater treatment. In this work, two carbon fiber species labeled CF-RH and CF-SCB were synthesized from two different agricultural wastes, namely, rice husk and sugarcane bagasse respectively. The structural properties of carbon fiber were verified by XRD, FTIR, and Raman, spectroscopy. Both nitrogen-adsorption–desorption BET surface area and TEM were performed to figure out the textural characteristics of the presented sorbents. The charges on surfaces of the fibers were detected via zeta potential analysis. The prepared carbon fibers were applied for uranium removal from aqueous solution by adsorption technique. The acquired data display that the equilibrium time was 240 min. The results of adsorption process are nicely fitted with pseudo-second-order-kinetic and Langmuir isotherm models. The maximum sorption capacity was 21.0 and 29.0 mg/g for CF-RH and CF-SCB, respectively. Sorption thermodynamics declare that adsorption of U(VI) is an endothermic, spontaneous, and feasible process. The picked findings of this study could emphasize high reliability of the introduced adsorbents in efficient tackling of water contaminants.

The present article investigates the fabrication of MnSnO 3, and Fe doped MnSnO 3 perovskite. We are reporting for the first time Fe doping perovskite material. The synthesis has been carried out under subcritical conditions. The optical, electrochemical, and luminescence properties were investigated. The structural determination of nanostructures has been carried out through XRD and Fourier transform infrared (FTIR). Furthermore, scanning electron micro-

“…This value is relatively normal for biomass-based solid carbon, as also reported in previous studies of different waste precursors especially sago waste [27] and Areca catechu husk waste. [28] After multi-activation sequences pyrolyzed at high temperature, the densities of GLAC-5, GLAC7, and GLAC9 were significantly degraded by 0.620, 0.440, and 0.560 g cm À 3 , respectively. Furthermore, KOH activation performed at low temperatures under a N 2 inert atmosphere allows significant degradation of the precursor's chemical and biological components, especially hydrogen, oxygen, sulphur, and nitrogen, followed by cleavage of hemicellulose and cellulose lignin chains.…”

Recently, micro/mesoporous biomass‐based functional carbon as an excellent electrode material and energy storage device has attracted massive attention due to the availability of abundant raw materials, adaptability to pore structure, good chemical‐physical behaviors, high conductivity, enhanced energy density, and long life cyclic stability. This study performs micro/meso carbon from the novel galangal leaves biomass through KOH and CO2 activation as electrodes material for symmetric supercapacitors. The activated carbon obtained showed a clear hierarchical pore structure with an excellent micro:meso ratio of 56.72 %:43.28 % which caused their high electrochemical properties. The carbon was further assembled into electrodes through a binder‐free solid disc designed to assess the electrochemical performance as a supercapacitor. The results indicated that the galangal leaves‐based adapted micro/mesoporous carbon obtained a high specific capacitance of 161 F g−1 at 1 A g−1. Additionally, the symmetric supercapacitor had a specific capacitance retention rate of 78 % at 10 mV s−1 and low resistance in the aqueous electrolyte of 1 M H2SO4. The maximum energy density was 19.53 Wh kg−1 at an optimum power density of 132.32 W kg−1. Therefore, the appropriate micro/mesopores carbon ratio based on the novel galangal leaves biomass can be considered as a good electrode material for high‐performance supercapacitor.
