Solar‐Driven Spin‐State Optimization in Co‐Based Catalysts for Enhanced Photothermal Ammonia Synthesis

Jinhao Li, Chunyao Fang, Yang Li, Shaoquan Li et autres

ABSTRACT Spin‐state engineering of active sites represents a key strategy for boosting catalytic performance, as demonstrated in thermal ammonia synthesis. However, conventional promoter‐mediated ground‐state spin modulation is inherently limited by the electronic structure of the catalyst, imposing a ceiling on achievable spin …

Enhanced Photocatalytic C–N Coupling by Synergistic Facet and Spin-State Modulation in Mixed-Valent WO x

Shaoquan Li, Shanshan Wu, Wenli Su, Zixian Li et autres

Abstract Urea is an essential chemical widely used in agriculture and consumer products, yet its conventional Bosch–Meiser synthesis is energy-intensive and carbon-intensive. Photocatalytic urea synthesis from N2, CO2, and H2O offers a sustainable alternative, but efficient C–N coupling is fundamentally limited by …

Nitrogen configuration engineering in carbon‐encapsulated Ni nanocatalysts for efficient CO 2 / MgCO 3 electroreduction

Meng Wang, Hongri Suo, Qiuhong Sun, Wenjing Dong et autres

Abstract Electrocatalytic CO 2 reduction into value‐added products enables carbon cycling and renewable energy storage. Developing non‐precious metal catalysts with high activity, selectivity, and long‐term stability remains challenging. Herein, we design nitrogen‐doped carbon‐encapsulated Ni nanoparticles (Ni‐N‐C) using layered double hydroxide as precursors. …

Sustainable Synthesis of Ammonium Nitrate From Air and Water via Tandem Plasma‐Electrolyzer System

Qiuhong Sun, Yao Xue, Hao Niu, Yang Li et autres

ABSTRACT Ammonium nitrate (NH 4 NO 3 ) is an indispensable high‐nitrogen fertilizer, yet its conventional industrial production via the energy‐intensive Haber–Bosch and Ostwald processes accounts for a significant global carbon footprint. Herein, we report an alternative method for directly synthesizing NH …

Highly Selective Coupled CO 2 ‐to‐CO Reduction and Anisyl Alcohol Oxidation Over In Situ‐Anchored CdSe Quantum Dots on MgCdAl‐LDH

Yue Wang, Wenjing Cao, Penghui Xu, Hongfan Jin et autres

ABSTRACT Photocatalytic CO 2 reduction reaction (CO 2 RR) is a promising route for solar‐to‐chemical conversion, yet its performance is still limited by weak CO 2 activation, rapid charge recombination, and the use of sacrificial reagents. Coupling CO 2 RR with value‐added …

Nearly all $k$-SAT functions are unate

József Balogh, Dingding Dong, Bernard Lidický, Nitya Mani et autres

We prove that a 1-o(1) fraction of all k -SAT functions of n Boolean variables are unate (i.e., monotone after first negating some variables), for any fixed positive integer k and as n \to \infty . This resolves a conjecture by Bollobás, …

Engineering matched activation on a bifunctional NiRu catalyst for efficient photothermal dry reforming of methane

Zhijia Yang, Yao Xue, Yujun Wang, Ruixue Wang et autres

Abstract Photothermal catalytic dry reforming of methane (DRM) offers a sustainable route for carbon conversion but suffers from kinetic imbalance between CH 4 and CO 2 activation. To address the fundamental challenge, we design a bifunctional NiRu‐MgO/MgAl 2 O 4 catalyst, where …
