EES:Bifacial Passivation of n-silicon Metal-insulator-semiconductor Photoelectrodes for Efficient OER and HER

Silicon-based (Si-based) junctions have been widely investigated in recent years as photoelectrochemical (PEC) water splitting photoelectrodes, including buried junctions and metal-insulator-semiconductor (MIS) Schottky junctions. However, Si-based MIS photoelectrodes suffer from low performance for PEC oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) because of the dilemma that a thin insulator cannot provide enough interfacial […]

JACS: Single-atom Mn-N4 Sites Catalyzed Peroxone Reaction for Efficient Production of Hydroxyl Radicals under Acidic Solution

The peroxone reaction between O3 and H2O2 has been deemed a promising technology to resolve the increasingly serious water pollution problem by virtue of the generation of superactive hydroxyl radicals (•OH), but it suffers greatly from an extremely limited reaction rate constant under acidic conditions (ca. less than 0.1 M–1 s–1 at pH 3). This […]

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 […]
