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
A facile and efficient γ-radiation strategy has been developed to incorporate surface-clean metal nanoparticles (NPs) into UiO-66-NH in the absence of stabilizing agents and additional reductants. This approach is enabled by metal ion reduction with active e and H species derived from water radiolysis. As a result, highly dispersed Pd NPs with narrow size distribution were generated and evenly dispersed in UiO-66-NH. More importantly, the radiation-reduced Pd NPs exhibit significantly enhanced catalytic activity and stability in olefin hydrogenation. Meanwhile, they are also highly active in the catalytic reduction of 4-nitrophenol to 4-aminophenol. Furthermore, the proposed radiation methodology could be successfully extended to prepare other metal NPs such as Au and Pt. Considering that γ-ray radiation is widely used in industry, this study provides a potentially scalable approach to incorporate metallic nanomaterials into metal-organic frameworks with improved catalytic performance.
