Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Adsorption is a promising technology for simultaneously capturing nitrogen oxides (NOx) from flue gases and recycling NO2 as a profitable chemical, for which a robust and efficient adsorbent provides the key step for success in practical applications. This work reports the enhancement of NOx adsorption performances with less cost of desorption energy on Cu-ZSM-5 zeolites modified by incipient-wetness impregnation coupled with microwave drying (Cu-ZSM-5_IM), in comparisons to H-ZSM-5, Na-ZSM-5 and conventionally liquid-phase ion-exchanged Cu-ZSM-5. The Cu-ZSM-5_IM renders record NOx adsorption capacity (qt,NOx) of 0.878mmol/g on zeolites from dry gas stream at sub-1000 ppm feed concentrations and room temperatures, and applicable qt,NOx of 0.1mmol/g from wet gas stream (42%RH at 298 K) with a moderate loading mass of copper (2.1%wt corresponding to ion exchange rate of 55%). The temperature programmed desorption of NOx on the optimal Cu-ZSM-5_IM saturated with NOx from wet gas stream exhibit primary peak temperature (~600 K) lower than reported Cu-ZSM-5 (~698 K) and NO2 as main component (72.6%) in desorbed NOx, which are beneficial for recycling in practice. Deeper insights into advantageous oxidative adsorption of NOx from CO2/N2/O2/H2O gas mixture on Cu-ZSM-5_IM with the rapid (≤700 s) and facile modification are discussed based on in-situ FTIR characterizations.
