The electrocatalytic C-N coupling for one-step urea synthesis under ambient conditions serves as the promising alternative to traditional synthetic protocol. However, hydrogenation of intermediate species hinders efficient synthesis. Herein, oxygen vacancy-enriched CeO2 was demonstrated electrocatalyst with stabilization crucial *NO via inserting into vacant sites, which is conducive subsequent process rather than protonation, whereas poor selectivity protonation observed on...
Abstract Electrochemical actuators directly converting electrical energy to mechanical are critically important for artificial intelligence. However, their transduction efficiency is always lower than 1.0% because electrode materials lack active units in microstructure, and assembly systems can hardly express the intrinsic properties. Here, we report a molecular-scale graphdiyne-based electrochemical actuator with high electro-mechanical of up 6.03%, exceeding that best-known piezoelectric...
Abstract Charged defects at the surface of organic–inorganic perovskite active layer are detrimental to solar cells due exacerbated charge carrier recombination. Here we show that charged can be benign after passivation and further exploited for reconfiguration interfacial energy band structure. Based on electrostatic interaction between oppositely ions, Lewis-acid-featured fullerene skeleton iodide ionization (PCBB-3N-3I) not only efficiently passivates positively but also assembles top...

Simple hydrophilic modification fights an opportunity to prevent oil contamination but fails eliminate severe decline. In essence, a “single‐defense” mechanism is insufficient build potent barrier against accumulated cake layer under filtration environment. This work reports “double‐defense” design by integrating polymer brushes and hydrogel on separation desired anti‐oil‐fouling property, where...

A solid electrolyte interphase (SEI) with robust mechanical property and high ionic conductivity is imperative for high-performance lithium metal batteries since it can efficiently impede the growth of notorious dendrites. However, difficult to form such a SEI directly from an electrolyte. In this work, crowding dilutant modified liquid (M-ILE) has been developed purpose.
