Light presents substantial potential in disease treatment, where the development of efficient photocatalysts could enhance utilization photocatalytic systems biomedicine. Here, we devised a novel approach to designing and synthesizing conjugated polymers for CO2 reduction, relying on multiple linear regression model built with theoretically calculated descriptors. We established logarithmic relationship between molecular structure CO yield identified poly(fluorene-co-thiophene) deviant (PFT) as optimal one. PFT excited regeneration ratio 231 nmol h–1 acetonitrile 46 an aqueous solution reaction selectivity 88%. Further advancements were made through liposomes encapsulating targeted macrophage delivery. By distributing liposome membranes, our constructed system efficiently generated situ from surrounding CO2. This localized production served endogenous signaling molecule, promoting desirable polarization macrophages M1 M2 phenotype. Consequently, cells reduced secretion pro-inflammatory cytokines (TNF-α, IL-6, IL-1β). also demonstrated efficacy treating lipopolysaccharide-induced inflammation cardiomyocytes under white light irradiation. Moreover, research provides comprehensive understanding intricate processes involved reduction by combination theoretical calculations experimental techniques including transient absorption, femtosecond ultrafast spectroscopy, infrared spectroscopy. These findings pave way further biomedical investigation.

Uncovering the Origin of Light‐Promoted Synergetic Effect and Y Doping in Enhancing Photothermocatalytic Dry Reforming of Methane on Ni/Ni‐Y₂‐Al₂O₃

Solar RRL, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 31, 2025

Photothermocatalytic dry reforming of methane (DRM) can convert CH 4 and CO 2 into syngas, offering an effective approach to reducing greenhouse gas emissions. However, photothermocatalytic DRM reaction generally needs a high light intensity surpassing 192 kW m −2 attain light‐fuel conversion. Also, catalysts applied are liable inactivation due carbon deposition. Herein, nanocomposite Ni nanoparticles supported on Ni‐ Y‐doped Al O 3 (Ni/Ni‐Y ‐Al ) is prepared. It achieves H production rates with light‐to‐fuel efficiency (29.2%) at lower (80.1 ). Meanwhile, it sustains excellent durability accomplishes 37‐fold reduction in deposition rate compared Ni/Al . The substantially enhanced catalytic activity resistance Ni/Ni‐Y correlated accelerating species (C*) oxidation (the rate‐determining steps DRM). This acceleration derives from the synergetic effect carbonate resulting Y doping, which participate C* via two separate pathways. When light, further facilitates oxidation. Simultaneously, immensely reduces activation energy, activates NiO bonds interface region, expedites between interface, enhancing resistance.
