Porous organic polymer enriched in Re functional units and Lewis base sites for efficient CO₂ photoreduction

Abstract

Photocatalytic reduction of CO2 into valuable chemicals or fuels is one of the promising solutions to mitigate climate changes. However, sound photocatalysts with sensitive responses to light, efficient enrichment and...

Trinuclear Fe Clusters for Highly Efficient CO2 Photoreduction

“…A Xe lamp (400–780 nm) was used to illuminate the solution, which was stirred at room temperature. Gas products in the system were analyzed online by a gas chromatograph (GC) every hour for a total of six times, and liquid products were qualitatively analyzed by 1 H nuclear magnetic resonance (NMR) spectra . Control experiments were conducted under similar conditions except for corresponding condition changes (Table S1).…”

“…Gas products in the system were analyzed online by a gas chromatograph (GC) every hour for a total of six times, and liquid products were qualitatively analyzed by 1 H nuclear magnetic resonance (NMR) spectra. 31 Control experiments were conducted under similar conditions except for corresponding condition changes (Table S1). The PXRD patterns revealed that they are isomorphic and consistent with the patterns reported in a previous literature (Figure 1b).…”

A Fully Conjugated Covalent Organic Framework with Oxidative and Reductive Sites for Photocatalytic Carbon Dioxide Reduction with Water

“…The Re-bpy complex is an excellent catalytic center for the reduction of CO 2 to carbon monoxide (CO). [20][21][22][23][24][25] The triazine structure has a wide range of applications in the reaction of H 2 O oxidation to produce O 2 . [26][27][28] Moreover, the low polarity À C=CÀ can bring great carrier mobility into the obtained material.…”

Photoexcited charge manipulation in conjugated polymers bearing a Ru(ii) complex catalyst for visible-light CO2 reduction

“…29 To date, organic polymer-based photocatalysts have been developed for CO 2 reduction under visible light. [30][31][32][33][34][35][36][37][38][39] Metalbased catalytic sites 31,[33][34][35]39 are frequently required to selectively reduce CO 2 although some organic polymers are reported to facilitate metal-free CO 2 reduction. 30,32,[36][37][38] Hence, the design principle, that maximizes the synergy between the conjugated skeleton and catalyst moiety, is strongly desired for achieving efficient photocatalytic CO 2 reduction.…”

“…30,32,[36][37][38] Hence, the design principle, that maximizes the synergy between the conjugated skeleton and catalyst moiety, is strongly desired for achieving efficient photocatalytic CO 2 reduction. Several combinations of the metal-based catalytic sites and organic polymers have been developed so far, 31,[33][34][35]39 while the design principles, particularly to manipulate the excited charge carrier have not been established satisfactorily. Herein, we show strong impacts of excited charge distribution in conjugated polymer photocatalysts with a site-selectively incorporated Ru(II) complex catalyst (Fig.…”
