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 […]

Nanostructured NiFe (Oxy)hydroxide with Easily Oxidized Ni Towards Efficient Oxygen Evolution Reaction

Water splits into hydrogen and oxygen electrochemically is one of the most promising strategies for the utilization and storage of solar energy. However, oxygen evolution reaction (OER) with sluggish kinetics hinders its larger-scale application. NiFe-based catalysts are one of the most efficient oxygen evolution catalysts (OECs). High-valence Ni is considered as active site or conductive […]

Low-Coordinated Edge Sites on Ultrathin Palladium Nanosheets Boost CO2 Electroreduction Performance

Electrochemical conversion of carbon dioxide (CO2) to value-added products is a promising way to solve CO2 emission problems. Thanks to the eminent conductivity and proper adsorption to intermediates, palladium has become a promising candidate for CO2 electroreduction (CO2ER). However, Pd-based nanocatalysts generally need a large overpotential to overcome energy barriers in generating highly selective products […]

Subsurface Catalysis-mediated Selectivity of Dehydrogenation Reaction

Progress in heterogeneous catalysis is often hampered by the difficulties of constructing active architecture and understanding reaction mechanism at molecular level due to the structural complexity of practical catalysts, in particular for multicomponent catalysts. Although surface science experiment and theoretical simulation help understand the detailed reaction mechanisms over model systems, the direct study of the […]
