Photoelectrochemical Conversion of Carbon Dioxide (CO₂) into Fuels and Value-Added Products

ACS Energy Letters, Journal Year: 2020, Volume and Issue: 5(2), P. 486 - 519

Published: Jan. 8, 2020

The conversion of carbon dioxide (CO2) into fuels and value-added products is one the most significant inventions to address global warming energy needs. Photoelectrochemical (PEC) CO2 can be considered as an artificial photosynthesis technique that produces formate, formaldehyde, formic acid, methane, methanol, ethanol, etc. Recent advances in electrode materials, mechanisms, kinetics, thermodynamics, reactor designs PEC have been comprehensively reviewed this article. adsorption activation CO2/intermediates at surface are key steps for improving kinetics conversion. efficiency could upgraded through utilization 2D/3D plasmonic metals, carbon-based catalysts, porous nanostructures, metal–organic frameworks, molecular biological molecules. defect engineered (by cation/anion vacancy, crystal distortion, pits, creation oxygen vacancies) Z-scheme heterojunctions, bioelectrodes, tandem photovoltaic–PEC reactors suitable options enhance low external bias.

Geometrical E → Z alkene isomerization is intimately entwined in the historical fabric of organic photochemistry and enjoying a renaissance (Roth et al. Angew. Chem., Int. Ed. Engl. 1989 28, 1193–1207). This consequence fundamental stereochemical importance Z-alkenes, juxtaposed with frustrations thermal reactivity that are rooted microscopic reversibility. Accessing excited state paradigms allow this latter obstacle to be circumnavigated by exploiting subtle differences photophysical behavior substrate product chromophores: provides molecular basis for directionality. While direct irradiation operationally simple, photosensitization via selective energy transfer enables augmentation repertoire include substrates not directly photons. Through sustained innovation, an impressive portfolio tailored small molecule catalysts range triplet energies now widely available facilitate contra-thermodynamic thermo-neutral reactions generate Z-alkene fragments. review intended serve as practical guide covering geometric alkenes enabled catalysis from 2000 2020, logical sequel excellent treatment Dugave Demange (Chem.

The incorporation of molecular switches in organic structures is great interest the chemical design stimuli-responsive materials that mimic complex functions living systems. Merocyanine dyes convert to spiropyran moieties upon exposure visible light have been extensively studied as they can be incorporated hydrated covalent networks will expel water when this conversion occurs and induce a volumetric shrinkage. We report here on sulfonate-based water-soluble photoswitch that, contrast well-known systems, triggers expansion hydrogels photons. Contraction turn observed under dark conditions highly reversible manner. novel behavior network was predicted by coarse-grained simulations system's structure. Using pH control polymeric differ lower critical solution temperature, we were able develop with tunable expansion. function systems developed led negative phototaxis plants could expand potential use sensors, soft robots, actuators.

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.
