An All‐in‐One Lignin‐Based Artificial Thylakoid Nanovesicle Via In‐Situ Confined Growth Strategy for High‐Efficient and Selectivity CO2 Photoreduction

Carbon Energy, EarlyView.
The low light/CO2 capture and slow dynamic transfer of photogenerated electrons hamper photocatalysts’ high activity and selectivity. Inspired by the chloroplast's photosynthesis mechanism, an all‐in‐one lignin‐based artificial thylakoid nanovesicle (AiO‐L‐ATN) is constructed using a confined growth strategy of lignin molecules. The performance of such

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.
