Metal‐Organic Frameworks for Photocatalytic Water Splitting and CO₂Reduction

Angewandte Chemie International Edition, Journal Year: 2023, Volume and Issue: 62(15)

Published: Jan. 23, 2023

Abstract Photocatalytic water splitting and carbon dioxide (CO 2 ) reduction provide promising solutions to global energy environmental issues. In recent years, metal‐organic frameworks (MOFs), a class of crystalline porous solids featuring well‐defined tailorable structures as well high surface areas, have captured great interest toward photocatalytic CO reduction. this review, the semiconductor‐like behavior MOFs is first discussed. We then summarize advances in over MOF‐based materials focus on unique advantage for clarifying structure‐property relationship photocatalysis. addition, some representative characterization techniques been presented unveil kinetics reaction intermediates systems. Finally, challenges, perspectives future directions are proposed.

Improving CO2 photoconversion with ionic liquid and Co single atoms

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: March 16, 2023

Photocatalytic CO2 conversion promises an ideal route to store solar energy into chemical bonds. However, sluggish electron kinetics and unfavorable product selectivity remain unresolved challenges. Here, ionic liquid, 1-ethyl-3-methylimidazolium tetrafluoroborate, borate-anchored Co single atoms were separately loaded on ultrathin g-C3N4 nanosheets. The optimized nanocomposite photocatalyst produces CO CH4 from water under UV-vis light irradiation, exhibiting a 42-fold photoactivity enhancement compared with nearly 100% towards reduction. Experimental theoretical results reveal that the liquid extracts electrons facilitates reduction, whereas trap holes catalyze oxidation. More importantly, maximum transfer efficiency for photoreduction, as measured in-situ μs-transient absorption spectroscopy, is found be 35.3%, owing combined effect of atoms. This work offers feasible strategy efficiently converting valuable chemicals.

Abstract The photocatalytic conversion of solar energy offers a potential route to renewable energy, and its efficiency relies on effective charge separation in nanostructured photocatalysts. Understanding the charge‐separation mechanism is key improving performance this has now been enabled by advances spatially resolved surface photovoltage (SRSPV) method. In Review we highlight progress made SRSPV mapping distributions at nanoscale determining driving forces heterogeneous photocatalyst particles. We discuss how arising from built‐in electric field, diffusion, trapping can be exploited optimized through design. also importance asymmetric engineering photocatalysts for separation.
