Metric Options: CountsSelecting 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 series of Pt–yLiBO/WO/ZrO (y = 0, 0.5, 1, 2 wt%) catalysts were prepared by varying the content of LiBO through the method of coimpregnation-calcination. The obtained catalysts were used for the selective hydrogenolysis of glycerol to 1,3-propanediol. Meanwhile, these catalysts were characterized by N adsorption and desorption (BET), CO chemisorption, X-ray diffraction (XRD), NH-temperature programmed desorption (NH-TPD), H-temperature programmed reduction (H-TPR), Fourier transform infrared spectroscopy (FTIR) and transmission electron microscopy (TEM). The results showed that Pt–1LiBO/WO/ZrO achieved the highest activity with glycerol conversion of 90.7% at 150 °C and 4 MPa and exhibited excellent stability over 200 h. Pt/WO/ZrO catalyst modified with LiBO was able to enhance catalytic activity and stability, since LiBO promoted the dispersion of Pt, increased the acid amount of the catalyst and strengthened the interaction between active components and support.
