Abstract Electrochemical nitrate reduction method (NitRR) is a low‐carbon, environmentally friendly, and efficient for synthesizing ammonia, which has received widespread attention in recent years. Copper‐based catalysts have leading edge due to their good adsorption of *NO 3 . However, the formation active hydrogen (*H) on Cu surfaces difficult insufficient, resulting large amount by‐product NO 2 − In this work, Pd single atoms suspended interlayer unsaturated bonds CuO formed dislocations...

Abstract As for Atrazine (C 8 H 14 ClN 5 ) degradation in soil, iron (Fe)-manganese (Mn) bimetallic biochar composites were proved to be more efficient persulfate (PS) activation than monometallic ones. The atrazine removal rates of Fe/Mn loaded + PS systems 2.17–2.89 times higher alone. Compared with biochar, the by (77.2–96.7%) mainly attributed synergy and adsorption due larger amounts metal oxides on surface. Fe-rich was free radicals (i.e., $${\text{SO}}_{4}^{ \cdot - }$$ <mml:math...

Metal oxide nanocrystals have been pursued for various applications in photovoltaics as a buffer layer. However, it remains challenging task to adjust their energy levels achieve better match of the donor–acceptor system. Herein, we report fabrication graphene quantum dots (GQDs) with bright blue photoluminescence by top-down strategy based on laser fragmentation posthydrothermal treatment. The GQDs demonstrate appropriate level positions and are used an intermediate layer between TiO2 P3HT...

Electrochemical nitrogen reduction reaction (NRR) is a promising method for ammonia synthesis under ambient conditions. However, the NRR performance limited to an extremely strong N≡N bond in N2 and competing hydrogen evolution reaction. Introducing oxygen vacancies (OVs) has been considered as forceful means accelerate sluggish kinetics. Herein, we reported design of Fe-doped NiMoO4 catalysts NRR. Fe doping can increase amount OVs catalyst contribute lattice strain enhancement, thereby...

Novel and less toxic quantum dot (QD) semiconductors are desired for developing environmentally benign colloidal solar cells. Here, the synthesis of novel lead/cadmium‐free neodymium chalcogenide Nd 2 (S, Se, Te) 3 QDs via solution‐processed method is reported first time. The results show that small‐bandgap semiconductor with a narrow size distribution ranging from to 8 nm can be produced, wide absorption band achieved by redshift owing quantization effect controlling initial loading...

Facile and sensitive determination of formaldehyde (FA) in indoor environments still remains challenging. Herein, a fluorescent probe, termed PHN@MOF, was synthesized by embedding the molecule N-propyl-4-hydrazine-naphthalimide (PHN) into metal–organic framework (MOF) for visual monitoring FA. The hydrazine group PHN acts as specific reaction with FA based on condensation reaction. host MOF (UiO-66-NH2) offers surrounding confinement space required Owing to enrichment effect molecular sieve...

In this work, a diverse set of chemically stable covalent organic frameworks (COFs) has been studied to understand their water adsorption behavior and how will affect CO2 capture performance in the COFs using grand canonical Monte Carlo (GCMC) simulations. Our results revealed three different types COFs: (1) initial small cluster formation was followed by early monolayer coverage with smooth hydrophilic surface, such as TpPa-1, TpPa-NO2, DAAQ-TFP; (2) hydrophobic functional groups presented...

A highly efficient inverted polymer solar cell (PSC) has been successfully demonstrated by using a ZnO nanoparticle (NP) and poly[(9,9-bis(3′-(N,N-dimethylamino)propyl)-2,7-fluorene)-alt-2,7-(9,9-dioctyfluorene)] (PFN) bilayer structure as an effective electron collecting layer. This ZnO/PFN is designed to combine the advantages of both PFN, based on performance comparison ZnO-only, PFN-only, devices in our work. NPs can serve transport buffer layer for reduced series resistance, while PFN...
