Achieving Overall Carbon Utilization from Organic Wastewater to Recover Solar Syngas via an Artificial Carbon Cycling System

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(44)

Published: June 29, 2024

Abstract Building artificial carbon cycling systems for the direct conversion of wastewater into value‐added solar fuels using renewable energy can contribute to achieving neutrality. Herein, a bifunctional photocatalyst comprising three‐dimensionally ordered Ti 3 C 2 T x /TiO nanoflowers is exploited tandem achieve efficient organic treatment with simultaneous CO resourcing. The highest efficiency achieved by optimal treat simulated containing rhodamine B (RhB), an enhanced primary production rate 10.02 µmol g −1 h and RhB degradation 77.6% after 1 illumination in anoxic environment. CO/H ratio produced syngas be readily tuned from 0.95 1.86 adjusting content. Mechanistic studies based on DFT, situ DRIFTS, LC‐MS /IC reveal that coupled photocatalytic reduction processes collectively undertake *HCOO intermediate coverage. This phenomenon triggers sustainable *CO under mild conditions crosses key rate‐limiting step ‐to‐CO conversion, thereby overall utilization treatment. study offers in‐depth insights design mechanisms highly effective systems.

Effect of temperature and pressure on electrochemical CO2 reduction: A mini review

Carbon Capture Science & Technology, Journal Year: 2023, Volume and Issue: 8, P. 100133 - 100133

Published: Aug. 6, 2023

The conversion of CO2 into high-value fuels and chemicals through electrochemical reduction reaction (CO2RR) might be one effective way to control current effects greenhouse gas emissions. However, the slow kinetics side reactions involved in process CO2RR lead low selectivity, inactivity limited durability. Additionally, is less selective for hydrocarbons due interference by hydrogen evolution (HER) multiple electron transfer processes process. In fact, sensitive dynamic changes catalyst non-catalyst components (i.e. micro-environment) at electrode/electrolyte interface. These factors regulate transportation reactive substances, also affect intermediates paths electrocatalytic reaction. There a large body literature this field that focuses on structure (chemical state, composition, crystal surface morphology) electrocatalyst CO2RR. Although impact conditions (including temperature pressure) should not underestimated, date, few studies have been done aspect. mini review, we first describe evaluation parameters, mainstream catalysts then, focusing effect pressure CO2RR, elucidate its controlling influence performance Finally, problems future development trends are summarized. We suggest review may provide some theoretical basis design catalytic processes.

Design of TiO₂@Carbon@Prussian Blue Core–Shell Nanorod Arrays for Enhanced Photoelectrochemical Performance

ACS Applied Energy Materials, Journal Year: 2024, Volume and Issue: 7(3), P. 1270 - 1276

Published: Jan. 26, 2024

The thoughtful design of effective photoanodes has drawn significant attention. Here, a Z-scheme core–shell TiO2@carbon@prussian blue (TiO2@C@PB) is designed for photoelectrochemical water splitting. TiO2@C@PB composite film larger absorption range, and the band gap decreased from 3.10 to 2.65 eV. Under illumination conditions, photoanode achieves photocurrent density 2.78 mA/cm2 at 1.23 V vs RHE, nearly 2.5 times higher than that pure TiO2. enhancement ascribed suppressed recombination photogenerated charges facilitated by heterojunction excellent conductivity carbon. This study offers an approach developing highly efficient water-splitting photoanodes.
