In this work, we have successfully triggered the aqueous auto‐redox reactions between reductive Ce(OH)3 and oxidative MnO4−/Pd2+ ions to form PdO/Mn3O4/CeO2 (PMC) nanocomposites. PMC could spontaneously self‐assemble into compact encapsulation on the surface of halloysite nanotubes (HNTs) to form the final one dimensional HNTs supported PMCs (HPMC). It is identified that there exists strong synergistic effects among the components of PdO, Mn3O4, and CeO2, and hence HPMC could show excellent performance on photoassisted thermal catalytic CH4 combustion that its light‐off temperature was sharply reduced to be 180 °C under visible light irradiation. Based on detailed studies, it is found that the catalytic reaction process well follows the classic MVK mechanism, and adsorption/activation of O2 into active oxygen species (O*) should be the rate‐determining step for CH4 conversion.

The performance of electrode material is correlated with the choice of electrolyte,h owever,h ow the solvation has significant impact on electrochemical behavior is underdeveloped. Herein, N-heteropentacenequinone (TAPQ) is investigated to reveal the solvation effect on the performance of sodium-ion batteries in different electrolyte environment. TAPQ cycled in diglyme-based electrolyte exhibits superior electrochemical performance,but experiences arapid capacity fading in carbonate-based electrolyte.T he function of solvation effect is mainly embodied in two aspects:o ne is the stabilization of anion intermediate via the compatibility of electrode and electrolyte,t he other is the interfacial electrochemical characteristics influenced by solvation sheath structure.Byrevealing the failure mechanism, this work presents an avenue for better understanding electrochemical behavior and enhancing performance from the angle of solvation effect.

Superior high‐rate performance and ultralong cycling life have been constantly pursued for rechargeable sodium‐ion batteries (SIBs). In this work, a facile strategy is employed to successfully synthesize porous CoxP hierarchical nanostructures supported on a flexible carbon fiber cloth (CoxP@CFC), constructing a robust architecture of ordered nanoarrays. Via such a unique design, porous and bare structures can thoroughly expose the electroactive surfaces to the electrolyte, which is favorable for ultrafast sodium‐ion storage. In addition, the CFC provides an interconnected 3D conductive network to ensure firm electrical connection of the electrode materials. Besides the inherent flexibility of the CFC, the integration of the hierarchical structures of CoxP with the CFC, as well as the strong synergistic effect between them, effectively help to buffer the mechanical stress caused by repeated sodiation/desodiation, thereby guaranteeing the structural integrity of the overall electrode. Consequently, CoxP@CFC as an anode shows a record‐high capacity of 279 mAh g−1 at 5.0 A g−1 with almost no capacity attenuation after 9000 cycles.
