Selective electroreduction of CO₂ to C₂₊ products on cobalt decorated copper catalysts

Chemical Synthesis, Год журнала: 2024, Номер 4(3)

Опубликована: Авг. 6, 2024

Cu-catalyzed electrochemical CO2 reduction reaction (CO2RR) to multi-carbon (C2+) products is often plagued by low selectivity because the adsorption energies of different intermediates are in a linear scaling relationship. Development Cu-based bimetallic catalysts has been considered as an attractive strategy address this issue; however, conventional avoid metals with strong CO prevent surface poisoning. Herein, we demonstrated that limiting amount Co CuCo can enhance C2+ product selectivity. Specifically, synthesized series CuCox trace amounts (0.07-1.8 at%) decorated on Cu nanowires using simple dip coating method. Our results revealed volcano-shaped correlation between loading and selectivity, CuCo0.4% catalyst exhibiting 2-fold increase compared nanowire sample. In situ Raman Infrared spectroscopies suggested optimal could stabilize oxide/hydroxide species under CO2RR condition promote CO, thus enhancing This work expands potential for developing CO2RR.

Multifunctional Thermally Activated Delayed Fluorescence Carbon Dots for Temperature‐Responsive Sensor, Information Encryption, and Organelle Imaging

Advanced Functional Materials, Год журнала: 2024, Номер 34(40)

Опубликована: Июль 10, 2024

Abstract Thermally activated delay fluorescence (TADF) has great potential for information encryption, temperature detection, and bioimaging due to its long‐lived luminescence, temperature‐sensitive high signal‐to‐noise ratio. However, it is still a challenge establish TADF in aqueous environments. In this study, the composite with (M‐FNCDs) prepared using fluorine‐nitrogen co‐doped carbon dots (FNCDs) melamine. It worth mentioning that M‐FNCDs show stable under long‐wavelength excitation (470 nm) Moreover, distinctive temperature‐responsive properties exhibit good linear relationships range of 77–370 K. Simultaneously, suspension as ink utilized realize encryption/decryption their afterglow cannot be quenched an solution. More importantly, biocompatibility can target mitochondria lysosomes living cells, first time achieve ratio low background signal imaging organelles. This work proposes new strategy prepare solutions extend material applications future.
