However, the SSEs still face the problems of low ionic conductivity, low Li⁺ transference number, and unstable interface with lithium metal. In this work, a novel strategy of frustrated Lewis pairs (FLPs) modulating solid polymer electrolytes (SPEs) has been firstly proposed that enables durable Li reversible cycling. The tunable strength of Lewis acid and base dual-active sites of nickel borate FLPs can synergistically promote both the dissociation of lithium salts and the transfer of Li⁺. As a consequence, the FLPs modulated SPEs (SPE-NiBO-150) exhibit high ionic conductivity of 4.92×10⁻⁴ ​S ​cm⁻¹, high Li⁺ transference number of 0.74, and superior interface compatibility with both lithium anode and LiFePO₄ cathode at room-temperature.

Herein, an efficient RWGS catalyst is constructed through <em>Enteromorpha prolifera</em>–derived N-rich mesoporous biochar (EPBC) supported atomic-level Cu-Mo₂C clusters (Cu-Mo₂C/EPBC). Unlike traditional activated carbon (AC) supported Cu-Mo₂C particles (Cu-Mo₂C/AC), the Cu-Mo₂C/EPBC not only presents the better graphitization degree and larger specific surface area, but also uniformly and firmly anchors atomic-level Cu-Mo₂C clusters due to the existence of pyridine nitrogen. Furthermore, the pyridine N of Cu-Mo₂C/EPBC strengthens an unblocked electron transfer between Mo₂C and Cu clusters, as verified by X-ray absorption spectroscopy. As a result, the synergistic effect between pyridinic N anchoring and the clusters interaction in Cu-Mo₂C/EPBC facilitates an improved CO selectivity of 99.95% at 500 ​°C compared with traditional Cu-Mo₂C/AC (99.60%), as well as about 3-fold CO₂ conversion rate. Density functional theory calculations confirm that pyridine N-modified carbon activates the local electronic redistribution at Cu-Mo₂C clusters, which contributes to the decreased energy barrier of the transition state of CO∗+O∗+2H∗, thereby triggering the transformation of rate-limited step during the redox pathway.

Herein, to alternate the tedious and polluting treatment processes, we propose a high-temperature molten-salt strategy to directly regenerate spent cathodes of LIBs, which can also overcome the barrier of the incomplete defects' restoration with previous low-temperature molten salts. The high-energy and stable medium environment ensures a more thorough and efficient relithiation reaction, and simultaneously provides sufficient driving force for atomic rearrangement and grains secondary growth. In consequence, the regenerated ternary cathode (R-NCM) exhibits significantly enhanced structural stability that effectively suppresses the occurrence of cracks and harmful side reactions. The R-NCM delivers excellent cycling stability, retaining 81.2% of its capacity after 200 cycles at 1 C.

The elimination performance of Fe₁/OPCN towards acid red 9, acid red 13 and amaranth containing similar azonaphthalene structure and increasing sulfonic acid groups increases gradually. The amaranth degradation rate of Fe₁/OPCN is 17.7 and 6.1 times as that of homogeneous Fenton and OPCN, respectively. In addition, Fe₁/OPCN also has more outstanding removal activities towards other contaminants with sulfonic acid and azo groups alone. The considerable enhancement for removing sulfonic azo contaminants of Fe₁/OPCN is mainly ascribed to the following aspects: (1) The modified Fe could enhance the adsorption towards sulfonic azo compounds to accelerate the mass transfer, act as e⁻ acceptor to promote interfacial charge separation, and trigger the self-Fenton reaction to convert in-situ generated H₂O₂ into •OH.

We highlight the crucial role of controllable synthesis and heterogeneous effect in tailoring perovskite properties to boost application efficacy.

The precision in controllable synthesis is essential for fabricating heterogeneous structures, where the synthesized precursor, shape, and surface ligand significantly influence the interfacial strength of the heterogenic interface. We also discuss the key features that must be improved for high-performance applications, exploring how heterogeneous effects can enhance performance and drive the development of heterogeneous devices in various applications, such as photodetectors, solar cells, light-emitting diodes, and photocatalysis.
