Trace to the Source: Self‐Tuning of MOF Photocatalysts

Advanced Energy Materials, Journal Year: 2023, Volume and Issue: 13(23)

Published: April 23, 2023

Abstract Benefitting from ultra‐high porosity, large specific surface area (SSA), and rich active sites, metal–organic frameworks (MOFs) have emerged as a star material in energy environment related applications, especially photocatalysis. In comparison with conventional photocatalysts, MOFs can be customized terms of electronic structure, photo‐responsiveness, morphological dimensions by rational design, which means that eliminate the need for other species to achieve enhanced photocatalytic performance, such metals, compounds, polymers, may introduce extra costs, time‐consuming, multi‐phase, or an unclear mechanism. Most previous review works MOF photocatalysis mixed self‐tuning assisted‐tuning, often gives incomplete understanding. this work, self‐tunning analyzing component (as clusters, ligands, inclusions), defect (defect engineering, linkers, oxygen vacancies (OVs), crystal facets, dimensions, amorphization) is summarized. Then, outstanding examples these strategies applied water redox, CO 2 /N reduction, organic conversion, environmental treatment are discussed. Finally, opportunities challenges faced analyzed different perspectives. This paper comprehensive systematic on enhance activity.

Abstract The photocatalytic transformation of carbon dioxide (CO 2 ) into carbon‐based fuels or chemicals using sustainable solar energy is considered an ideal strategy for simultaneously alleviating the shortage and environmental crises. However, owing to low utilization sunlight inferior catalytic activity, conversion efficiency CO photoreduction far from satisfactory. In this study, a MOF‐derived hollow bimetallic oxide nanomaterial prepared efficient . First, unique ZIF‐67‐on‐InOF‐1 heterostructure successfully obtained by growing secondary Co‐based ZIF‐67 onto initial InOF‐1 nanorods. corresponding counterpart has larger specific surface area after acid etching, oxidized H‐Co 3 O 4 /In material exhibits abundant heterogeneous interfaces that expose more active sites. band structure corresponds well with photosensitizer [Ru(bpy) ]Cl , which results in high yield 4828 ± 570 µmol h −1 g stable activity over consecutive six runs, demonstrating adequate performance. This study demonstrates rational design MOF‐on‐MOF heterostructures can completely exploit synergistic effects between different components, may be extended other nanomaterials as promising catalysts practical storage.

Mimicking Frustrated Lewis Pairs on Graphitic Carbon Nitride for CO₂ Photoreduction

ACS Catalysis, Journal Year: 2023, Volume and Issue: 13(22), P. 14530 - 14539

Published: Oct. 27, 2023

Photocatalytic carbon dioxide (CO2) reduction is an emerging approach to synthesizing monoxide (CO) but still suffers from poor selectivity and low catalytic efficiency because of the high energy barrier toward *COOH formation. Herein, we report selective high-efficiency photosynthesis CO with a boron (B)- sulfur (S)-codoped graphitic nitride (g-C3N4) catalyst (B,S-CN), which shifts rate-determining-step (RDS) CO2 protonation adsorption. This realized by local mimicking frustrated Lewis pairs (M-FLPs) constructed abundant electron-deficient S electron-rich N adjacent B. The "push–pull" effect provided as-designed metal-free M-FLP configuration allows spontaneous formation *CO intermediates through balancing adsorption energy, as evidenced theoretical calculations in situ characterizations. In addition free-energy changes, B codoping can also promote separation transfer charges improve utilization rate light. Strikingly, B,S-CN exhibits 100% average yield 313.20 μmol g–1 h–1 (70.7 times that bulk g-C3N4). study provides strategy for development highly photocatalysts paves way rational intermediate regulation FLP configuration.
