Photoelectrochemical CO2-to-fuel conversion with simultaneous plastic reforming

چکیده

Solar-driven conversion of CO2 and plastics into value-added products provides a potential sustainable route towards circular economy, but their simultaneous in an integrated process is challenging. Here we introduce versatile photoelectrochemical platform for that coupled to the reforming plastic. The perovskite-based photocathode enables integration different CO2-reduction catalysts such as molecular cobalt porphyrin, Cu91In9 alloy formate dehydrogenase enzyme, which produce CO, syngas formate, respectively. Cu27Pd73 anode selectively reforms polyethylene terephthalate glycolate alkaline solution. overall single-light-absorber system operates with help internal chemical bias under zero applied voltage. performs similarly bias-free, dual-light absorber tandems shows about 10?100-fold higher production rates than those photocatalytic suspension processes. This finding demonstrates efficient CO2-to-fuel plastic-to-chemical promising technology powered by sunlight. A solar-driven hybrid has been developed greenhouse gas waste fuels chemicals high efficiency selectivity.

Standalone anion- and co-doped titanium dioxide nanotubes for photocatalytic and photoelectrochemical solar-to-fuel conversion.

Several strategies are currently being investigated for conversion of incident sunlight into renewable sources of energy, and photocatalytic or photoelectrochemical production of solar fuels can provide an important alternative. Titanium dioxide (TiO2) has been heavily investigated as a material of choice due to its excellent optoelectronic properties and stability, and anion-doping proposed as...

Two novel oxy-fuel power cycles integrated with natural gas reforming and CO2 capture

Two novel system configurations were proposed for oxy-fuel natural gas turbine systems with integrated steam reforming and CO2 capture and separation. The steam reforming heat is obtained from the available turbine exhaust heat, and the produced syngas is used as fuel with oxygen as the oxidizer. Internal combustion is used, which allows a very high heat input temperature. Moreover, the turbine...

Plasma Reforming of Diesel Fuel

The use of a plasma reformer for the generation of hydrogen rich gas from diesel fuel has been investigated. A system that is normally used for investigating natural gas reforming has been modified in order to investigate the reforming of heavy liquid fuels. The composition of the reformate has been investigated as a function of the composition of the reagents. The use of a one-step reformer/wa...

Demonstration of CO2 Conversion to Synthetic Transport Fuel at Flue Gas Concentrations

A mixture of 1and 2-butanol was produced using a stepwise synthesis starting with a methyl halide. The process included a carbon dioxide utilization step to produce an acetate salt which was then converted to the butanol isomers by Claisen condensation of the esterified acetate followed by hydrogenation of the resulting ethyl acetoacetate. Importantly, the CO2 utilization step uses dry, dilute ...
