Anthraquinone inhibitors of photosystem II electron transport [PDF]

, 1988
Various substituted 9,10-anthraquinones were tested for their inhibitory activity on photosystem II electron transport. Maximal inhibitory activity was achieved if the positions adjacent to one of the quinone carbonyl groups were unsubstituted or ...

Doped Ta3N5 Semi‐Transparent Photoanode Enabling Stable Solar Redox Flow Cell Operation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Synergistic Al:TiO2 underlayer and La doping stabilize semitransparent Ta3N5 photoelectrodes for over 90 h of continuous operation in alkaline solution. The solar redox flow cell demonstrated 12 photocharge–discharge cycles at ∼55% coulombic efficiency using a K4Fe(CN)6|1,5‐DHAQ chemistry. Solar redox flow cells (SRFCs) are photoelectrochemical devices

Chlorine-Free Depolymerization of Commercial PMMA via Oxygen-Centered Radicals. [PDF]

Angew Chem Int Ed Engl
A new chlorine‐free photothermal method enables sustainable recycling of plastics with C–C backbones under mild conditions. Driven by an oxygen‐centered radical pathway with ppm levels of anthraquinone catalyst, it eliminates hazardous chlorinated solvents, achieving an impressive 97% depolymerization conversion.

Precisely Constructed Asymmetric Coordination Tuned High‐Spin Co Sites for Sacrificial Agent‐Free H2O2 Photocatalytic Production

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The asymmetric Co–N2O2 coordination structure was precisely constructed through the assembly of Salen COF. The high‐spin (t2g4eg3$$ {\mathrm{t}}_{2\mathrm{g}}^4{\mathrm{e}}_{\mathrm{g}}^3 $$) Co center enables Pauling‐type O2 adsorption, inhibiting the cleavage of the O–O bond. π‐d conjugation enhances charge separation and transport.

Electron‐Rich Para‐Methylpyridine‐Functionalized TEMPO Empowers Long‐Lived Neutral Aqueous Organic Redox Flow Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Three methylpyridine‐functionalized TEMPOs were synthesized through an electron‐rich regulation strategy. The calculation of transition states supported the highest reaction efficiency of para‐MePy‐TEMPOs, which outperformed its analogues to have the best performance of AORFBs, opening a new avenue for exploring TEMPO‐based catholytes.
