Durable nitrogen-coordinated iron single-atom catalysts are achieved by an innovative strategy, featuring a protective carbon encapsulation from additional organic compound coating. Adequate control of the carbon coating transforms edge-defective Fe sites into in-plane and durable FeN4 sites, significantly enhancing ORR stability without any performance...

Herein, an organic-inorganic hybrid cathode is explored, HNaV6O16·4H2O-Glu (HNVO-Glu), through a guest material-mediated NVO synthesis strategy utilizing glutamic acid to induce Na substituted by proton and enable crystal transformation of Na2V6O16·3H2O. Consequently, the HNVO-Glu exhibits a high specific capacity, excellent Zn2+ diffusion capability...

It is revealed that the working principle through the water molecule has triple roles in driving moisture electric generators: 1) intrinsic H2O absorption on the material surface and splitting into hydroxy group and proton. 2) freely diffused protons derived from the H2O splitting work as the ions charge carriers; 3) via the hydrogen bond of the water...

The review seeks to delve into the essence of catalyst structural degradation by clarifying the irreversible cationic and anionic overoxidation. Simultaneously, the connections between mainstream OER reaction mechanisms and cationic/anionic overoxidation are explored. Additionally, 4 state-of-the-art strategies to curb catalyst overoxidation, providing...

This review summarizes the strategies for precise modulation and densification of single-atom catalysts (SACs). Focusing on their advantages in enhancing the product's yield, improving the energy storage efficiency, and revealing the unique effects, the applications of these SACs are discussed. Finally, the challenges and perspective of precise modulation...

In this work, polymer:Y6 organic solar cells are found prominent thermal degradation dominated by open-circuit voltage (V OC) and fill factor (FF) losses. The underlying mechanism is elucidated that the polymer orientation transition from edge-on to face-on induces V OC decay, while demixing and aggregation intercept electron transportation leading...
