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
The direct conversion of CO to aromatics is an effective strategy for simultaneously achieving carbon neutrality and its resource utilization. However, it is a great challenge to efficient CO conversion to high value-added aromatics due to the chemical inertness and characteristics of multi-path conversion of CO. To address this, a series of nanosized ZSM-5 zeolites [NZ5(x)] with different acid amount and strength were synthesized using a seed-induced template-free method via changing the initial gel composition. The CrO nanoparticle was prepared by simple precipitation method. The performance of the CrO/NZ5(x) bifunctional catalysts composed of CrO and nano-ZSM-5 zeolites with different acidity, and mixed CrO with NZ5 (50) by different ways in the CO hydrogenation reaction was studied. The CrO/NZ5(50) catalyst with suitable acidity and closest metal-acid site distance exhibited the highest aromatics selectivity of 87.2% among all hydrocarbon products at CO single-pass conversion of 13.6%, which is due to the synergistic effect between the acid sites of the nanosized ZSM-5 zeolite and metal sites provide by CrO with abundant oxygen vacancies.
