“…[18][19][20][21][22][23][24][25][26][27][28] Compared to the activated carbon, TMO nanostructures exhibited comparable adsorption capacities and induced selectivity based on surface functionalization. α-MoO 3 as an important TMO, has been widely investigated and has presented a wide range of potential applications in the fields of electrochromism/photochromism devices, 29,30 SERS, 31 gas sensors, 32 field emission devices, 33 capacitors, 34 catalysts and photocatalysts, 35,36 H 2 generation, 37 and lithium-ion batteries, 38,39 etc. Recently, MoO 3 has also been studied as a critical dye adsorbent due to its high selectivity, good adsorption capacity, desirable mechanical strength, easy separation, and reusability.…”
