Sub-nanometric Pd clusters on porous nanorods of CeO2 (PN-CeO2) with a high dispersion 73.6% exhibit the highest catalytic activity and best chemoselectivity for hydrogenation nitroarenes to date. For 4-nitrophenol, catalysts yield TOF ∼44059 h(-1) 4-aminophenol >99.9%. The superior performance can be attributed cooperative effect between highly dispersed sub-nanometric hydrogen activation unique surface sites PN-CeO2 concentration oxygen vacancy an energetically geometrically preferential...
Abstract Identification on catalytic sites of heterogeneous catalysts at atomic level is important to understand mechanism. Surface engineering defects metal oxides can construct new active and regulate activity selectivity. Here we outline the strategy by controlling surface nanoceria create solid frustrated Lewis pair (FLP) oxide for efficient hydrogenation alkenes alkynes. Porous nanorods ceria ( PN -CeO 2 ) with a high concentration acidic two adjacent Ce 3+ . The neighbouring lattice...
Hydrogen spillover phenomenon of metal-supported electrocatalysts can significantly impact their activity in hydrogen evolution reaction (HER). However, design active faces grand challenges due to the insufficient understandings on how overcome this thermodynamically and kinetically adverse process. Here we theoretically profile that interfacial charge accumulation induces by large work function difference between metal support (∆Φ) sequentially strong proton adsorption construct a high...

Effective activation of CO2 is a prerequisite for efficient utilization in organic synthesis. Precisely controlling the interfacial events solids shows potential activation. Herein, defect-enriched CeO2 with constructed frustrated Lewis pairs (FLPs, two adjacent Ce3+···O2–) effectively activates via interactions between C/Lewis basic lattice O2– and O atoms CO2/two acidic Ce3+ ions. Selective cyclic carbonate production from catalytically tandem protocol olefins used to demonstrate FLP-inspired
The development of heterogeneous frustrated-Lewis-pair (FLP) catalysts from homogeneous FLP conception is great promise in practical applications. While our recent discovery has shown that all-solid FLPs can be created on ceria via surface oxygen vacancy regulation (Zhang et al. Nat. Commun. 2017, 8, 15266), a sound understanding the intrinsic property and reactivity solid still expected. Here we present comprehensive theoretical study (Ce···O) constructed CeO2(110) (100) surfaces by using...
Pristine Ru generally shows unsatisfying activity for the electrocatalytic hydrogen evolution reaction (HER). How to activate its HER through facile methodologies is very challenging. Recently, metal-supported electrocatalysts integrating metals with efficient adsorption and supports desorption delivered a high performance metal-to-support spillover process, where small metal–support work function difference (ΔΦ) was identified as criterion successful interfacial spillover. Herein, we...
Abstract Carbon neutrality initiative has stimulated the development of sustainable methodologies for hydrogen generation and safe storage. Aqueous-phase reforming methanol H 2 O (APRM) attracted particular interests their high gravimetric density easy availability. Thus, to efficiently release significantly suppress CO at low temperatures without any additives is pursuit APRM. Herein, we demonstrate that dual-active sites Pt single-atoms frustrated Lewis pairs (FLPs) on porous nanorods CeO...
The low-temperature reverse water-gas shift (RWGS) reaction faces the following obstacles: low activity and unsatisfactory selectivity. Herein, dual-active sites of platinum (Pt) clusters frustrated Lewis pair (FLP) on porous CeO2 nanorods (Ptcluster /PN-CeO2 ) provide an interface-independent pathway to boost high performance RWGS at temperatures. Mechanistic investigations illustrate that Pt can effectively activate dissociate H2 . FLP sites, instead metal support interfaces, not only...
Activation of aryl chlorides for Suzuki–Miyaura coupling (SMC) reactions is particularly challenging heterogeneous catalysts due to the chemically inert nature C–Cl bond. Herein, multifunctional Pd/Au/porous nanorods CeO2 (PN-CeO2) with a well-defined spatial configuration deliver first example activate strong bond under irradiation visible light (>400 nm) at room temperature. PN-CeO2 basicity not only provides photogenerated electrons enrich electron density metal nanoparticles but also...
Nanomaterials with intrinsic enzyme-like characteristics exhibit their great potentials as alternatives to natural enzymes. Among various enzymes, the finding of substitutes DNA photolyases, a family photoenzymes for repairing ultraviolet (UV)-induced damage by forming cyclobutane pyrimidine dimers (CPDs) between two adjacent thymines in strand, is still unsuccessful. CPDs raise significant health concerns skin diseases. Essentially, photolyases selectively split into monomers photoelectrons...
Abstract Despite the known efficacy of CeO 2 as a promoter in alkaline hydrogen evolution reaction (HER), underlying mechanism this effect remains unclear. CoS , pyrite‐type HER electrocatalyst, suffers from sluggish kinetics and severe catalyst leaching due to its weak water dissociation oxygen‐related corrosion. Herein, it is demonstrated that interfacial Lewis acid–base Ce∙∙∙S pairs ‐loaded effectively improve catalytic activity durability. In nanowire array electrodes, these with unique...
Adsorption of molecules on active sites heterogeneous catalysts significantly affects their catalytic performance, which provides a perspective to understand the process/mechanism at atomic level and establish structure–function relationships. This Perspective illustrates strong correlation between adsorption reactants CeO2-based improved activity and/or selectivity for various transformations.

Rational design of heterogeneous catalysts with dual-active sites provides a strategy to achieve efficient and selective hydrogenation under mild conditions by breaking the restriction Brønsted-Evans-Polanyi scaling relations. Steric hindrance effects encapsulating active components inside porous shells have been widely adopted for hydrogenation. However, this methodology is always at cost limited catalytic activity due restricted mass transfer through shell inevitable sacrifice part shells....
