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
In this work, Z-scheme Pt-GdCrO 3 -Bi 2 MoO 6 ternary heterojunction (Pt-GCO-BMO) are fabricated and applied for realizing effective photoreduction of CO 2 to solar fuels. The constructed photocatalyst displayed significantly enhanced response to visible light, boosted carrier separation efficiency, improved CO 2 adsorption level, and increased strong reduction capacities. Therefore, the production of CO (15.35 μmol/g/h) and CH 4 (8.49 μmol/g/h), as dominating products, can be increased by 4.7 and 9.1 times as compared to that of pure BMO, respectively. In addition, the CO and CH 4 generation rates of the Pt-GCO-BMO photocatalyst shown little change after five reuse cycles. The Pt-GCO-BMO photocatalyst also displayed a better photocatalytic activity for bisphenol A removal than either GCO or BMO only, achieving 78.43% degradation efficiency under the visible light irradiation. Overall, a promising strategy to design and prepare a high efficient Z-scheme photocatalyst with strong oxidative/reductive bands for solar-driven CO 2 photoreduction and wastewater purification has been demonstrated through the Pt-GCO-BMO heterojunction photocatalyst.
