Angew Chem: The Interplay between Structure and Product Selectivity of CO2 Hydrogenation

Identification of the active structure under reaction condition is of great importance for rational design of heterogeneous catalysts, but which is often hampered due to their structural complexity. This paper describes the interplay between the surface structure of Co3O4 and the CO2 hydrogenation reaction. Experimental results combined with theoretical calculations show that the Co3O4 with […]

ACS Catal: Adsorption Preference Determines Segregation Direction: A Shortcut to More Realistic Surface Models of Alloy Catalysts

A correct description of active sites is the precondition towards reaction mechanism study and catalyst screening. In many cases, high-symmetry and ideally ordered crystalline surfaces are used to represent the reactive sites. However, reaction-induced surface segregation and restructuring weaken the rationality of simply employing the suggested most stable surfaces. This paper describes an establishment of […]

JACS: Ultrathin PdAu Shells with Controllable Alloying Degree on Pd Nanocubes towards ECRR

Electrocatalytic reduction of carbon dioxide (CO2ER) to reusable carbon resources is a significant step to balance the carbon cycle. This Communication describes a seed-mediated growth method to synthesize ultrathin Pd–Au alloy nanoshells with controllable alloying degree on Pd nanocubes. Specifically, Pd@Pd3Au7 nanocrystals (NCs) show superior CO2ER performance, with a 94% CO faraday efficiency (FE) at […]

Angew Chem: Activation and Spillover of Hydrogen on Sub‐1 nm Pd Nano‐clusters Confined within Sodalite Zeolite for Semi‐hydrogenation of Alkynes

The search for efficient nontoxic catalysts able to perform industrial hydrogenations is a topic of interest, transversal to many catalytic processes. This communication describes a mechanistic phenomenon of activation and spillover of hydrogen for remarkable selectivity of semi‐hydrogenation of acetylene over sub‐1 nm Pd nanoclusters confined within sodalite (SOD) zeolite (Pd@SOD). Specifically, hydrogen is dissociated […]

Chem Sci: Achieving efficient and robust catalytic reforming on dual-sites of Cu species

Catalytic reforming provides a practical technique for on-board hydrogen production in fuel cell applications. The high energy density, easy transportation and non-toxicity of biomass-derived dimethyl ether (bio-DME) offer potential to replace methanol for on-board steam reforming (SR). Presently, the reaction mechanism over conventional Cu-based SR catalysts remains elusive, limiting the rational design of highly efficient […]

JACS: The Crucial Role of Surface Hydroxyls on the Activity and Stability in ECRR

The role of surface hydroxyls is significant for understanding catalytic performance of metallic oxides for CO2 electroreduction reaction (CO2ER). This Communication describes, employing SnOx as a model system, how to moderate coverage of hydroxyl to derive a stable Sn branches catalyst for CO2ER with a 93.1% Faradaic efficiency (FE) of carbonaceous products. With use of […]

Angew Chem: Adjustable Reduction Potential of Electrons via Quantum Confinement for Selective CO2 Photoreduction to Methanol

CH3OH production from photocatalytic CO2 reduction reaction (PCRR) represents a promising route for the clean utilization of renewable resources, but serious charge recombination, unsatisfied stability and poor selectivity limit its practical application. This paper describes the design and fabrication of 0D/2D materials with polymeric C3N4 nanosheets and CdSe quantum dots (QDs) to enhance the separation […]

Energy Environ. Sci.:Photoelectrochemical CO2 Reduction to Adjustable Syngas on Grain-boundary-mediated a-Si/TiO2/Au Photocathodes with Low Onset Potentials

Photoelectrochemical (PEC) CO2 reduction reaction (CRR) in aqueous medium is among the most promising methods to produce renewable fuel with solar and water as the energy and electron source. But the high negative bias remains a prerequisite to achieve an appreciable conversion at present due to the large overpotential of CO2 reduction. This communication describes […]

Nat Commun: Breaking the Scaling Relationship via Thermally Stable Pt/Cu Single Atom Alloys for Catalytic Dehydrogenation

Due to the existence of scaling properties of adsorption energies on transition metal surfaces, the enhancement of the catalytic activity is frequently accompanied by side reactions leading to a reduction in selectivity for the target product. Herein, by systematically screening Pt alloy materials using density functional theory calculations, we developed an approach to breaking the […]
