Highly Dispersed Potassium-Based Nanowire Structure for Selectively Capturing Trace Hydrogen Chloride in H2S/CO2 Environments
Currently, developing efficient and selective dechlorination materials has become one of the hot issues in the chemical industry. In this work, a novel supported potassium carbonate nanowire adsorbent was synthesized facilely and applied to capture hydrogen chloride (HCl) at 150 degrees C. The highly dispersed network structure of wires contributed to a high chlorine capacity of 2.28 mmol/g. In addition, the adsorbent showed an extremely high selectivity to capture trace HCl, even under the existence of hydrogen sulfide and rich carbon dioxide. Such an adsorbent with a facile preparation process, large chlorine capacity, low cost, and strong selectivity will keep an obvious industrial application prospect.
