“…Specifically, the carbon precursor is uniformly blended with activated agent through impregnation or grind method, followed by annealing at proper temperature under inner gas atmosphere [ 73 ]. Common chemical activators employed in reaction process includes ZnCl 2 [ 74 , 75 ], H 3 PO 4 [ 76 ], and KOH [ 77 , 78 ], etc. Among them, KOH activation is a well-developed method for introducing pores into biomass-derived carbon materials because of its mild activation temperature, higher production, and developed porosity with larger surface area (up to 3000 m 2 g −1 ) [ 79 ].…”

HIGHLIGHTS• The synthetic methods and corresponding mechanisms of porous carbon (PC)-based nanostructures from biomass resource are reviewed.• The application of biomass-derived PC in microwave absorption is discussed in terms of structure and composition optimization.ABSTRACT Currently, electromagnetic (EM) pollution poses severe complication toward the operation of electronic devices and biological systems. To this end, it is pertinent to develop novel microwave absorbers through compositional and structural design. Porous carbon (PC) materials demonstrate great potential in EM wave absorption due to their ultralow density, large surface area, and excellent dielectric loss ability. However, the large-scale production of PC materials through low-cost and simple synthetic route is a challenge. Deriving PC materials through biomass sources is a sustainable, ubiquitous, and low-cost method, which comes with many desired features, such as hierarchical texture, periodic pattern, and some unique nanoarchitecture. Using the bio-inspired microstructure to manufacture PC materials in mild condition is desirable. In this review, we summarize the EM wave absorption application of biomass-derived PC materials from optimizing structure and designing composition. The corresponding synthetic mechanisms and development prospects are discussed as well. The perspective in this field is given at the end of the article.

The electrode made using this doped annealed carbon material shows good stability up to 20 charge discharge cycles. The CV curves taken at different annealing temperatures represent the EDL mechanism owing to the capacitive behavior of the material.…”

Summary Supercapattery devices are currently gaining remarkable attention since they have the potential to meet the demand for high energy density with no constrain on power density, which is much higher in magnitude than supercapacitors and batteries. Nanomaterials based on metal oxides, phosphates, phosphides and sulfides are well utilized in the development and improvement of hybrid energy storage devices. Challenges facing nowadays by this technology, is to enhance the energy density with no compromise on the power density of the device. Merging the merits of the two technologies (supercapacitor and battery) in a single device will provide high specific power from the capacitive part while the battery counterpart overcomes the high energy concerns. In this review, we have focused our study on the recent progress regarding novel nanomaterials as an electrode material, comprising of high specific capacity and cyclic life, for state‐of‐the‐art supercapattery devices. Furthermore, this study may also enlighten the energy performance of the metal oxides, phosphates, phosphides, sulfides and nitrides as an excellent electrode material for high‐performance energy storage devices.

“…Among these, water resources, as an irreplaceable essential resource for mankind, have become one of the most urgent problems in the world. 1,2 Capacitive deionization technology is a new type of water treatment technology in which ions are moved to the oppositely charged electrode and adsorbed onto the electrical double-layer (EDL) formed between the solution and the electrode interface. Once the voltage is removed, the ions adsorbed by the electrodes can be immediately released into the solution.…”
