Photo fuel cell (PFC) offers an attractive way to simultaneously convert solar and biomass energy into electricity. Photocatalytic oxidation biomass oxidation on a semiconductor photoanode together with a dark electrochemical reduction of oxygen molecules on a metal cathode (usually Platinum) in separated compartment are the common configuration for a PFC. Herein, we report a membrane-free PFC based on dual-electrode of W-doped BiVO4 photoanode and polyterthiophene photocathode for solar stimulated biomass derivatives-to-electricity conversion. Air and water-soluble biomass derivatives can be directly used as reagents. The optimal device yields an open circuit voltage (Voc) of 0.62 V, a short circuit current (Jsc) of 775 μA cm-2, and a power density (Pmax) of 82 μW cm-2 with glucose as the feeding under tandem illumination, which, to our knowledge, outperforms that of dual-photoelectrode photocatalytic fuel cells previously reported. Neither costly separating membrane nor platinum catalyst is required in the present PFC. Our work may inspire rational designs for devices of cost-effective electricity generation from renewable resources.
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 20 December 2016.
All research outputs
#16,546,863
of 24,417,958 outputs
Outputs from ChemSusChem
#2,523
of 5,585 outputs
Outputs of similar age
#265,340
of 429,755 outputs
Outputs of similar age from ChemSusChem
#52
of 133 outputs
Altmetric has tracked 24,417,958 research outputs across all sources so far. This one is in the 32nd percentile – i.e., 32% of other outputs scored the same or lower than it.
So far Altmetric has tracked 5,585 research outputs from this source. They receive a mean Attention Score of 3.4. This one has gotten more attention than average, scoring higher than 52% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 429,755 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 37th percentile – i.e., 37% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 133 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 60% of its contemporaries.
