The limitations of the Haber-Bosch reaction, particularly high-temperature operation, have ignited new interests in low-temperature ammonia-synthesis scenarios. Ambient N2 electroreduction is a compelling alternative but impeded by low ammonia production rate (mostly <10 mmol gcat-1 h-1), small partial current density (<1 mA cm-2), and high-selectivity hydrogen-evolving side reaction. Herein, we report that room-temperature nitrate catalyzed strained ruthenium nanoclusters generates at...
Photocatalytic CO2 reduction (PCR) is able to convert solar energy into chemicals, fuels, and feedstocks, but limited by the deficiencies of photocatalysts in steering photon-to-electron conversion activating CO2, especially pure water. Here we report an efficient, water CO2-to-CO photocatalyzed sub-3-nm-thick BiOCl nanosheets with van der Waals gaps (VDWGs) on two-dimensional facets, a graphene-analog motif distinct from majority previously reported usually bearing VDWGs lateral facets....
Abstract The objective of photocatalytic CO 2 reduction (PCR) is to achieve high selectivity for a single energy‐bearing product with efficiency and stability. bulk configuration usually determines charge carrier kinetics, whereas surface atomic arrangement defines the PCR thermodynamic pathway. Concurrent engineering structures therefore crucial achieving goal PCR. Herein, an ultrastable highly selective using homogeneously doped BiOCl nanosheets synthesized via inventive molten strategy...
Regulating the distribution of reactive oxygen species generated from H2 O2 activation is prerequisite to ensuring efficient and safe use in chemistry life science fields. Herein, we demonstrate that constructing a dual Cu-Fe site through self-assembly single-atomic-layered Cu5 nanoclusters onto FeS2 surface achieves selective with high efficiency. Unlike its unitary Cu or Fe counterpart, sites residing at perimeter zone /FeS2 interface facilitate adsorption barrierless decomposition into...
Room-temperature molecular oxygen (O2) dissociation is challenging toward chemical reactions due to its triplet ground-state and spin-forbidden characteristic. Herein, we demonstrate that BiOCl of chlorine dual vacancies can photocatalytically dissociate O2 into monatomic reactive (•O-) for the ring opening aromatic refractory pollutants deep oxidation. The electron-rich geometry-flexible remarkably lengthen O-O bond adsorbed from 1.21 2.74 Å, resulting in rapid subsequent •O- formation....
The photocatalytic O2 activation for pollutant removal highly depends on the controlled generation of desired reactive oxygen species (ROS). Herein, we demonstrate that robust excitonic effect BiOBr nanosheets, which is prototypical singlet (1O2) production to partially oxidize NO into a more toxic intermediate NO2, can be weakened by surface boronizing via inducing staggered band alignment from bulk and simultaneously generating vacancy (VO). destabilizes excitons facilitates their...
Abstract Photocatalytic reduction of CO 2 to value‐added liquid fuels is a promising approach alleviate the global energy and environmental problems. However, highly selective production C2+ products from reaction (CO RR) very difficult because sluggish CC coupling reaction. An asymmetric coupled heteronuclear photocatalyst designed overcome this limitation. The new catalyst contains single atoms nickel cobalt loaded on titanium dioxide. It exhibits an impressive 71% selectivity for acetic...
Electrocatalytic reduction of carbon dioxide into value-added chemical fuels is a promising way to achieve neutrality. Bismuth-based materials have been considered as favorable electrocatalysts for converting formic acid. Moreover, size-dependent catalysis offers significant advantages in catalyzed heterogeneous processes. However, the size effects bismuth nanoparticles on acid production not fully explored. Here, we prepared Bi uniformly supported porous TiO2 substrate electrocatalytic by...
Abstract Microscale zero‐valent iron is one of the most important multifunctional environmental remediation materials, yet its passivated oxide shell hampers transportation inherent electrons. Herein, authors exert tensile strain onto mZVI by interstitial boron doping that destabilizes lattice FeFe interactions, thereby liberating electrons trapped in reservoir. Tensile also upshifts equilibrated Fermi level at iron/iron Ohmic heterojunction, thus populating with abundant for robust heavy...
An appealing strategy in the direction of circular chemistry and sustainable nitrogen exploitation is to efficiently convert NOx pollutants into low-toxic products simultaneously provide crop plants with metabolic nitrogen. This study demonstrates that such a scenario can be realized by defect- morphology-coengineered Ni–Fe-layered double hydroxide (NiFe-LDH) comprising ultrathin nanosheets. Rich oxygen vacancies are introduced onto NiFe-LDH surface, which facilitate charge carrier transfer...
Seawater is one of the most important CO2 sequestration media for delivering value-added chemicals/fuels and active chlorine; however, this scenario plagued by sluggish reaction rates poor product selectivity. Herein, we first report synthesis nitrogen-doped BiOCl atomic layers to directly split carbon-sequestrated natural seawater (Yellow Sea, China) into stoichiometric CO (92.8 μmol h-1 ) HClO (83.2 under visible light with selectivities greater than 90 %. Photoelectrons enriched on...

Abstract Electrochemical urea oxidation offers a sustainable avenue for H 2 production and wastewater denitrification within the water-energy nexus; however, its wide application is limited by detrimental cyanate or nitrite instead of innocuous N . Herein we demonstrate that atomically isolated asymmetric Ni–O–Ti sites on Ti foam anode achieve selectivity 99%, surpassing connected symmetric Ni–O–Ni counterparts in documented Ni-based electrocatalysts with below 55%, also deliver evolution...

For purpose sustainable development, metal decrement and performance improvement are highly desirable development CER anodes. Herein, we demonstrate that surface titanium amorphization crucial to regulate coordination environment stabilized Ir single atoms efficient durable monolithic...
Two-dimensional semiconductors have attracted considerable attention in recent years because of their ability to utilize solar energy mitigate environmental pollution through reactive oxygen species (ROSs) and synthesize fuels using superfluous CO2 as a raw material. However, low-dimensional materials usually display robust Coulomb interaction between electron hole pairs strong structure confinement ability, thus leading the formation electroneutral excitons. In light this, excitonic effects...
