Impregnation on activated carbon for removal of chemical warfare agents (CWAs) and radioactive content

Membranes for the life sciences and their future roles in medicine

“…Although almost all pathogens can be decomposed by hydrolysis or incineration at a high temperature, these methods are not suitable for the real-time protection of human bodies, especially for medical workers and soldiers. Activated charcoal has been widely used in protective clothing and facial masks to safeguard the wearer from the invasion of hazardous substances, but it is too heavy and retains too much moisture to be comfortable [163] , [164] , [165] . Moreover, the harmful substances are physically absorbed not decomposed by using this method, resulting in the disposal of protective equipment after usage.…”

Nano-silver functionalized spherical activated carbon with enhanced dipropyl sulfide adsorption capacity and antibacterial properties

“…Related studies have shown that the adsorption and catalytic degradation performance of carbon materials toward chemical warfare agents can be improved by loading appropriate metals on the surface. 9,10 A typical example is that transition metals such as zinc, copper, molybdenum, vanadium and chromium are loaded on carbon materials, resulting in enhanced adsorption capacities for chemical warfare agents like soman, sarin, and mustard gas. 11–13 In recent years, nano-silver has received much concern as a functional material in the field of biochemical protection and detection due to their non-toxic, catalytic and electrochemical properties.…”

In Situ Synthesis of Hierarchical Porous Zr-MOFs on Columnar Activated Carbon and Application in Toxic Gas Adsorption

“…13−15 As widely used adsorbents with mature technology, activated carbons exhibit hierarchical porous structures and desirable adsorption performance. 16,17 However, few studies have focused on using activated carbons, especially shaped activated carbons, as carriers to exploit MOFs/matrix composites. Herein, using columnar activated carbon (CAC) as supports, we constructed a series of Zr-MOFs/CAC composites with high mesoporosity for the in situ synthesis of Zr-MOFs.…”

“…Various aerogels, , such as cellulose aerogels, graphene aerogels, and silica aerogels, have been used as matrices to explore MOFs/matrix composites with hierarchical porous structures. Research has shown that hierarchical porous materials are beneficial to the accommodation and permeability of gas molecules, owing to the synergistic effects among different pore architectures, which are beneficial to the increase in gas adsorption performance. − As widely used adsorbents with mature technology, activated carbons exhibit hierarchical porous structures and desirable adsorption performance. , However, few studies have focused on using activated carbons, especially shaped activated carbons, as carriers to exploit MOFs/matrix composites.…”
