Strain engineering offers an attractive strategy for improving intrinsic catalytic performance of a heterogeneous catalyst. Herein, we successfully create strain into layered indium sulfide (In2S3) at atomic scale via introducing oxygen coordination and sulfur vacancy using wet-chemistry method. The atomically strained In2S3 exhibits greatly enhanced CO2 photoreduction performance, achieving to CO conversion rate 5.16 μmol gcatalyst−1 h−1 under visible light illumination in ambient air. In-situ spectroscopic measurements together with theoretical calculations indicate that the features lattice disordered defects on surface, which provides rich uncoordinated sites induces structural distortion, resulting modified band structure promotes adsorption/activation boosts photogenerated charge carriers' separation during photoreduction. This work new approach rational design photocatalysts reduction Achieving visible-light-driven air is significant yet challenging. Here, authors introduce promoted activation boosted carrier atmospheric

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 (Pd−CuO) were prepared by low temperature treatment, located subjected shear stress dynamic effect support promote conversion into ammonia. The catalysis had an ammonia yield 4.2 mol. g cat −1 h , Faraday efficiency 90 % production at −0.5 V vs. RHE. situ characterization theoretical calculations indicate that effects carriers under obviously hydrogen, reduce reaction energy barrier decision‐making step further generation.

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 leading improvement electron transport rate catalytic active In 0.1 M Na2SO4 solution, 5% Fe-NiMoO4 achieves NH3 yield 15.36 μg h-1 mgcat.-1 Faradaic efficiency 26.85% -0.5 V versus RHE. Furthermore, exhibits excellent stability (up 13 h) during
