Low‐Power Tunable Micro‐Plasma Device for Efficient and Scalable CO2 Valorization

Advanced Science, EarlyView.
Tunable in‐chip micro‐plasma generation leads to efficient, low‐power and scalable CO2 valorization under atmospheric pressure via vibrational excitation mechanism. Abstract Valorizing CO2 into chemical building blocks via efficient electrified processes could significantly decrease carbon emissions.

Heme/NADH Mimics Co‐Decorated Allosteric Capsules for Regulating Oxygen Activation and Upregulating Intracellular Methionine Depletion

Advanced Science, EarlyView.
Through modifying the switchable µ‐oxo bridged FeIII‐porphyrins moiety and NADH mimics into a metal‐organic capsule, multiple responsive manners for O2 activation, chemical oxygenation and metabolic transformation have been demonstrated for upregulating intracellular methionine depletion and accumulation of methionine sulfoxide to achieve effective ...

Spin‐State Engineering of Iron Phthalocyanine D‐Orbitals via Atomic Fe‐N4 Coupling for Enhanced Oxygen Reduction Reaction

Advanced Science, EarlyView.
We propose a strategy of coupling FePc to atomically dispersed Fe‐N4 sites, and design a composite catalyst (FePc‐Fe‐NCNT) that can synergistically tune the 3d electronic configuration of Fe. This strategy triggers a low‐spin to intermediate‐spin transition at Fe centers, balancing the adsorption and dissociation of oxygen‐containing intermediates. The

Scalable and Integrated Photocatalytic Reactor Systems for Solar‐to‐Fuel Production: Photoredox and Photoreforming Processes

Advanced Energy Materials, EarlyView.
Solar fuels and other value‐added chemicals derived from light‐driven reactions are highly desirable. Although advanced photoactive materials have been reported, demonstrations of their feasibility in large‐scale production are needed. Hence, strategies and recent efforts in scaling up photocatalytic reactors and integrating them into comprehensive ...

Toward Complete CO2 Electroconversion: Status, Challenges, and Perspectives

Advanced Energy Materials, EarlyView.
Electrocatalytic CO2 reduction and CO2 batteries face challenges in achieving complete CO2 conversion with high conversion rates and Faradaic efficiency simultaneously. Existing systems compromise one for the other with incomplete CO2 conversion and inefficiencies, hindering practical applications. This perspective highlights state‐of‐the‐art progress,
