Engineering an Oxygen‐Binding Protein for Photocatalytic CO₂Reductions in Water

Angewandte Chemie International Edition, Год журнала: 2023, Номер 62(20)

Опубликована: Март 14, 2023

Abstract While native CO 2 ‐reducing enzymes display remarkable catalytic efficiency and product selectivity, few artificial biocatalysts have been engineered to allow understanding how the work. To address this issue, we report cobalt porphyrin substituted myoglobin (CoMb) as a homogeneous catalyst for photo‐driven conversion in water. The activity selectivity were optimized by varying pH concentrations of enzyme photosensitizer. Up 2000 TON(CO) was attained at low with (15 %), while 74 % reached increasing loading but compromised TON(CO). generation overall further improved introducing positively charged residues (Lys or Arg) near active stie CoMb, which demonstrates value tuning secondary coordination sphere enhance performance protein‐based photocatalytic system.

Energy Science & Engineering, Год журнала: 2024, Номер 12(9), С. 3967 - 3981

Опубликована: Июль 16, 2024

Abstract Since the industrial revolution, global anthropogenic CO 2 emissions have surged dramatically to unsustainable levels, resulting in severe issues, such as warming, extreme weather events, and species extinction. In response this critical situation, extensive efforts been undertaken across academia, industry, policymaking sectors deploy carbon capture, utilization, storage (CCUS) technologies. Here, we present annual summary of CCUS for year 2023. We begin by discussing trends atmospheric concentrations, then offer an up‐to‐date progress policy, respectively. analyze number categories publications highlight some key breakthroughs. industry sector, meticulously collect information on operational commercial carbon‐capture facilities. Furthermore, elucidate significant policy announcements reforms diverse regions. This concise comprehensive report aims inspire ongoing collaboration among policymakers toward advancing neutrality.

Electrocatalytic CO₂ reduction by a cobalt porphyrin mini-enzyme

Chemical Science, Год журнала: 2025, Номер unknown

Опубликована: Янв. 1, 2025

Cobalt-mimochrome VI*a (CoMC6*a), a synthetic mini-enzyme with cobalt porphyrin active site, is developed as biomolecular catalyst for electrocatalytic CO2 reduction in water. The catalytic turnover number reaches ∼14 000 CO production selectivity of 86 : 5 over H2 under the same conditions. Varying applied potential and pK proton donor was used to gain insight into basis selectivity. protected site CoMC6*a proposed enhance conditions that typically favor by related catalysts. activity change only marginally air, indicating excellent oxygen tolerance.

Self-Assembling Peptide–Co-PPIX Complex Catalyzes Photocatalytic Hydrogen Evolution and Forms Hydrogels

Molecules, Год журнала: 2025, Номер 30(8), С. 1707 - 1707

Опубликована: Апрель 10, 2025

The sustainable production of carbon-free fuels such as hydrogen is an important goal in the search for alternative energy sources. Herein, we report a peptide-based system light-driven evolution from water under neutral conditions. M1 peptide ABC triblock polymer featuring two coiled-coil alpha-helical regions flanking water-soluble, polyanionic, intrinsically disordered region. formed hydrogel at high concentrations upon binding to cobalt protoporphyrin IX. This process driven by terminal regions, which coordinate metalloporphyrin through histidine residues and form helical oligomers interconnected flexible, resulting network formation. Co-M1 catalyzes irradiation presence photosensitizer sacrificial electron donor; activity eight times higher than that free Co-PPIX.
