We describe a synergistic utilization of cerium photocatalysis and photoinduced electron transfer catalysis that enables an atom- step-economical ring expansion readily available cycloalkanols. This operationally simple protocol provides rapid access to privileged synthetically challenging bridged lactones. The mild catalytic manifold has been adapted continuous flow for scale-up applications employed the concise synthesis polycyclic core nepalactones.
Currently, the highest-performing lead-free perovskite solar cells utilize element tin. Tin halide perovskites, typically FASnI3, resemble their lead-based counterparts in optoelectronic properties but possess dissimilar crystallization kinetics. To tackle usually poor film quality, we introduced trimethylthiourea (3T) to spin coating of FASnI3 films. This bifunctional ligand greatly improved morphology and texture films by spreading joining individual crystal grains. Accordingly,...
The intermediacy of alkoxy radicals in cerium-catalyzed C–H functionalization via H-atom abstraction has been unambiguously confirmed. Catalytically relevant Ce(IV)–alkoxide complexes have synthesized and characterized by X-ray diffraction. Operando electron paramagnetic resonance transient absorption spectroscopy experiments on isolated pentachloro Ce(IV) alkoxides identified as the sole heteroatom-centered radical species generated ligand-to-metal charge transfer (LMCT) excitation....
Reversible protonic ceramic electrochemical cells (R-PCECs) offer the potential for high-efficiency power generation and green hydrogen production at intermediate temperatures. However, commercial viability of R-PCECs is hampered by sluggish kinetics oxygen reduction reaction (ORR) evolution (OER) within conventional air electrodes operating reduced To address this challenge, work introduces a novel approach based on simultaneous optimization bulk-phase metal-oxygen bonds in-situ formation...
Recently, layered perovskites attracted great attention for its excellent stability and light-emitting property. However, most of them rely on the toxic element lead their emission quantum yields are generally low.
