In this work, we introduce cyclic diacyl peroxides as effective O-electrophiles for cross-coupling with boronic acids, a process that likely proceeds via a Pd(II)/Pd(IV) catalytic cycle. The success of this method can be attributed to the higher oxidative potential of cyclic diacyl peroxides and the ability to avoid the elimination of CO₂ in high-valent Pd intermediates. Additionally, the Pd(IV) complex with cyclic diacyl peroxide maintains a ground state singlet spin state with no radical character on the acetate and carboxylate ligands that facilitate the transmetalation step. The reaction produces a variety of aryl esters with an additional carboxylic acid group as a platform for further functionalization.","PeriodicalId":9,"journal":{"name":"ACS Catalysis ","volume":"208 1","pages":""},"PeriodicalIF":12.9,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143418447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In nature, metalloenzymes use second-sphere interactions like hydrogen bonding and electrostatic interactions to control the rate and selectivity to these multielectron and multiproton reactions, e.g., NO₂^–, SO₂, H⁺, etc. Recent developments have suggested that hydrogen bonding as well as electrostatic interactions in molecular catalysts, like iron porphyrins, results in selective 2e^–/2H⁺ reduction of CO₂, as well, to CO or HCOOH and suppresses competitive reduction of protons to H₂, which occurs at similar reduction potentials. However, until date, there is no direct and systematic investigation of these two different second-sphere effects on multielectron, multiproton transformation like CO₂ reduction. A series of iron porphyrins is synthesized where second-sphere hydrogen bonding and electrostatic interactions are installed in the <i>ortho</i> position of a <i>meso</i>phenyl group in an iron tetraphenyl framework. The results show that both hydrogen bonding and electrostatic interactions can facilitate the selective reduction of CO₂ to CO by iron porphyrins using H₂O as a proton source. In iron porphyrins with hydrogen bonding interactions, the selectivity for CO increases with an increase in H₂O concentrations. However, in the iron porphyrins with electrostatic interactions, the selectivity for CO decreases, and the iron porphyrin becomes more selective for H₂ evolution instead at higher H₂O concentrations. Excited-state lifetime measurements and molecular dynamics simulations of porphyrins suggest that the solvation of the cationic groups in the periphery of the porphyrin by H₂O leads to an increased concentration of water near the metal center, which promotes H₂ evolution over CO₂ reduction.","PeriodicalId":9,"journal":{"name":"ACS Catalysis ","volume":"2 1","pages":""},"PeriodicalIF":12.9,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143418453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

FSP1 is myristoylated and associated with membranes, where it regenerates the reduced forms of quinones using electrons from NADPH. The quinol products intercept reactive oxygen species and ameliorate lipid peroxidation, preventing ferroptosis, a form of regulated cell death. While FSP1 enzymes have been reported to have 6-OH-FAD as an active cofactor, aerobic titration of the enzyme with NADPH in the presence and absence of ubiquinone (UQ) reveals that this is more likely an artifact and that the native form of HsFSP1 has unmodified FAD as the cofactor. Moreover, HsFSP1 suppresses the reaction of the reduced FAD with molecular oxygen three-fold which, from a kinetic standpoint, severely limits the opportunity for cofactor modification. The isolated form of the enzyme has NADP⁺ bound and the rate of release of this product limits the observed rate of reduction by NAD(P)H molecules. The reduction of substrate quinones occurs rapidly (≥2000 s^–1), dictating that the rate of turnover is wholly defined by the rate of release of NADP⁺ from the HsFSP1·NADP⁺ complex. Given that HsFSP1 does not distinguish ubiquinone from ubiquinol by significant differences in binding affinity, this pronounced catalytic commitment to quinone reduction serves to overcome presumed kinetic limitations imposed by the abundance of ubiquinol relative to ubiquinone in the membrane.

Nevertheless, how to decrease the energy barrier of the two-electron (2e^–) ORR process and photosynthesize H₂O₂ efficiently is still challenging. Herein, three hydroxyl-functionalized donor–acceptor covalent organic frameworks (COFs) are synthesized for photocatalytic H₂O₂ production under visible-light irradiation (420 ≤ λ ≤ 780 nm). It is observed that the dihydroxyl functionalization (2,5-DhaTph and 2,3-DhaTph) facilitates the transportation of photogenerated carriers between acceptor and donor units and accelerates the kinetics of the rate-limiting step of the ORR when comparing with the monohydroxyl functionalization (2-DhaTph). Further, 2,5-DhaTph with para-position hydroxyl functionalization shows higher H₂O₂ photosynthesis efficiency than 2,3-DhaTph (ortho-positioned hydroxyl), probably due to the greater exposure of catalytically active sites. This is supported by a better structural symmetry of 2,5-DhaTph, which contributes to higher crystallinity and higher specific surface areas. Electron paramagnetic resonance (EPR) spectra and theoretical calculations show that 2,5-DhaTph produces the *OOH intermediates with a reduced energy barrier, resulting in a high H₂O₂ production rate of 2103.1 μmol h^–1 g^–1. Regulating the amount of hydroxyl substituents and their location on the donor units of COFs is an effective strategy to boost photogenerated carrier transfer and reduce the energy barrier of O₂-to-H₂O₂ conversion.","PeriodicalId":9,"journal":{"name":"ACS Catalysis ","volume":"50 1","pages":""},"PeriodicalIF":12.9,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143401876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we deposit Ir on Pt black nanoparticles via a H₂ gas-promoted reduction of Ir³⁺ ions, exploiting the high activity of Pt toward H₂ oxidation. The affinity between Ir and Pt was proven in electrodeposition experiments, which supports the favored deposition of Ir on Pt and the delayed bulk deposition of Ir on Ir. This method yields a nanosized core–shell catalyst with an Ir content adjustable between 4 and 30 wt % Ir. Intuitively, an increased Ir content results in higher OER activity, while the ORR activity decreases. We show that the Pt core and the strong interaction between Pt and Ir affect the electrocatalytic behavior, since the ORR activity does not decrease to the same extent as the OER activity increases with progressive Ir deposition. The simplicity and robustness of this synthesis method are demonstrated by an upscaling of the synthesized catalyst amount by a factor of 10, revealing its great potential.","PeriodicalId":9,"journal":{"name":"ACS Catalysis ","volume":"29 1","pages":""},"PeriodicalIF":12.9,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143393948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The resulting ZIS-5, rich in cation vacancies, achieved a 3.6-fold higher 2,5-diformylfuran (DFF) yield (92.0%) than the pristine ZIS (25.8%) for the visible-light-driven photocatalytic air-oxidation of 5-hydroxymethylfurfural (HMF).

Density functional theory (DFT) simulations revealed that the presence of dual Zn and In defects endows the catalyst with defect states that intersect the Fermi level and lower work function.
