Tuning the microwave absorption capacity of TiP2O7 by composited with biomass carbon

Simultaneous Achievement of High-Yield Hydrogen and High-Performance Microwave Absorption Materials from Microwave Catalytic Deconstruction of Plastic Waste

“…Since the Z value is far below 1 in the frequency of 2-8 GHz, most of the electromagnetic waves are reflected at the surface of the absorber. The value of the attenuation constant increases from 55 to 234 as the frequency increases from 2 to 18 GHz (Figure 5b), which is much higher than previously reported for pure carbon (below 25) [47]. The above analysis shows that the excellent MA performance of the solid residue of the Catalyst/PE−1 system is due to the good impedance matching and high attenuation constants, especially in the frequency range of 14-18 GHz.…”

Hierarchically Porous Carbon/α‐Fe@Fe3C Absorbers Derived from Luffa Sponge with Efficient Microwave Absorption

“…The EAB of LF‐1000 is 3.86 GHz. Table 1 shows the microwave absorption properties of other biomass‐based materials [12,59–67] . Compared with these materials, the luffa sponge has competitive performance at a thinner thickness.…”

“…Table 1 shows the microwave absorption properties of other biomass-based materials. [12,[59][60][61][62][63][64][65][66][67] Compared with these materials, the luffa sponge has competitive performance at a thinner thickness. Figure 10 (e-h) shows the color maps of the j Z in /Z 0 j values of the four samples.…”

NiCo@NPC@CF nanocomposites derived from NiCo-MOF/cotton for high-performance electromagnetic wave absorption

“…11 The graded porous carbon/nickel composite material derived from the corn cobs also has an EAB of 5.0 GHz and an RL min of −42.51 dB. 12 In addition, many biomass materials are used to prepare electromagnetic wave absorbing materials, such as wood, 10 pine pollen, 13 fish scales, 14 coconut shells, 15 filter paper, 16 and so on. Among them, cotton is composed of cellulose fibers which usually contain very few inorganic impurities, making them a promising candidate for use with carbon fibers.…”
