Electrocatalytic upcycling of polyethylene terephthalate to commodity chemicals and H2 fuel

Nature Communications, Journal Year: 2021, Volume and Issue: 12(1)

Published: Aug. 17, 2021

Abstract Plastic wastes represent a largely untapped resource for manufacturing chemicals and fuels, particularly considering their environmental biological threats. Here we report electrocatalytic upcycling of polyethylene terephthalate (PET) plastic to valuable commodity (potassium diformate terephthalic acid) H 2 fuel. Preliminary techno-economic analysis suggests the profitability this process when ethylene glycol (EG) component PET is selectively electrooxidized formate (>80% selectivity) at high current density (>100 mA cm −2 ). A nickel-modified cobalt phosphide (CoNi 0.25 P) electrocatalyst developed achieve 500 1.8 V in membrane-electrode assembly reactor with >80% Faradaic efficiency selectivity formate. Detailed characterizations reveal in-situ evolution CoNi P catalyst into low-crystalline metal oxy(hydroxide) as an active state during EG oxidation, which might be responsible its advantageous performances. This work demonstrates sustainable way implement waste value-added products.

Constraining the atmospheric limb of the plastic cycle

Proceedings of the National Academy of Sciences, Journal Year: 2021, Volume and Issue: 118(16)

Published: April 12, 2021

Significance Microplastic particles and fibers generated from the breakdown of mismanaged waste are now so prevalent that they cycle through earth in a manner akin to global biogeochemical cycles. In modeling atmospheric limb plastic cycle, we show most plastics derived legacy production has continued build up environment. Roads dominated sources microplastics western United States, followed by marine, agriculture, dust emissions downwind population centers. At current rate increase (∼4% per year), understanding consequences atmosphere should be priority.

Microplastic effects on carbon cycling processes in soils

PLoS Biology, Journal Year: 2021, Volume and Issue: 19(3), P. e3001130 - e3001130

Published: March 30, 2021

Microplastics (MPs), plastic particles <5 mm, are found in environments, including terrestrial ecosystems, planetwide. Most research so far has focused on ecotoxicology, examining effects performance of soil biota controlled settings. As pivots to a more ecosystem and global change perspective, questions about soil-borne biogeochemical cycles become important. MPs can affect the carbon cycle numerous ways, for example, by being themselves influencing microbial processes, plant growth, or litter decomposition. Great uncertainty surrounds nano-sized particles, an expected by-product further fragmentation MPs. A major concerted effort is required understand pervasive functioning soils ecosystems; importantly, such needs capture immense diversity these terms chemistry, aging, size, shape.
