Recent Progress in Metal‐Free Covalent Organic Frameworks as Heterogeneous Catalysts

Small, Journal Year: 2020, Volume and Issue: 16(24)

Published: May 17, 2020

Abstract Covalent organic frameworks (COFs), connecting different units into one system through covalent bonds, are crystalline porous materials with 2D or 3D networks. Compared conventional such as inorganic zeolite, active carbon, and metal‐organic frameworks, COFs a new type of well‐designed pore structure, high surface area, outstanding stability, easy functionalization at the molecular level, which have attracted extensive attention in various fields, energy storage, gas separation, sensing, photoluminescence, proton conduction, magnetic properties, drug delivery, heterogeneous catalysis. Herein, recent advances metal‐free versatile platform for catalysis wide range chemical reactions presented synthetic strategy promising catalytic applications COF‐based catalysts (including photocatalysis) summarized. According to types reactions, this review is divided following five parts discussion: achiral catalysis, chiral conversion, photocatalytic conversion water splitting reduction carbon dioxide), pollutant degradation. Furthermore, remaining challenges prospects also presented.

Covalent organic frameworks with high quantum efficiency in sacrificial photocatalytic hydrogen evolution

Nature Communications, Journal Year: 2022, Volume and Issue: 13(1)

Published: April 29, 2022

Abstract Organic semiconductors offer a tunable platform for photocatalysis, yet the more difficult exciton dissociation, compared to that in inorganic semiconductors, lowers their photocatalytic activities. In this work, we report charge carrier lifetime is dramatically prolonged by incorporating suitable donor-acceptor (β-ketene-cyano) pair into covalent organic framework nanosheet. These nanosheets show an apparent quantum efficiency up 82.6% at 450 nm using platinum as co-catalyst H 2 evolution. Charge kinetic analysis and femtosecond transient absorption spectroscopy characterizations verify these modified have intrinsically lower binding energies longer-lived carriers than corresponding without unit. This work provides model gaining insight nature of short-lived active species polymeric photocatalysts.

Published: Jan. 1, 2022

As a new generation of porous materials, organic polymers (POPs), have recently emerged as powerful platform heterogeneous photocatalysis. POPs are constructed using extensive synthesis methodologies, with various functional units being connected via high-energy covalent bonds. This review systematically presents the recent advances in for visible-light driven transformations. Herein, we firstly summarize common construction strategies POP-based photocatalysts based on two major approaches: pre-design and post-modification; secondly, categorize methods reaction types constructing POPs. We then classify introduce specific reactions current light-driven POP-mediated Finally, outline state development problems faced transformations by POPs, present some perspectives to motivate reader explore solutions these confront challenges process.
