Atomically dispersed metal catalysts often exhibit high catalytic performances, but the metal loading density must be kept low to avoid the formation of metal nanoparticles, making it difficult to improve the overall activity. Diverse strategies based on creating more anchoring sites (ASs) have been adopted to elevate the loading density. One problem of such traditional methods is that the single...
Single‐Atom Catalysts
The low loading of single‐atom catalysts makes it difficult to improve their overall activity. In article number 2200073, Ang Li, Erjun Kan, Li Song, Jinlong Gong, and co‐workers report a chemical scissors strategy to saturate the anchoring sites for single atoms, which elevates the loading of Pd single atoms even on bare substrate with only a few anchoring sites.
The electroreduction of CO2 to CO provides a potential way to solve the environmental problems caused by excess fossil fuel utilization. Loading transition metals on metal oxides is an efficient strategy for CO2 electroreduction as well as for reducing metal usage. However, it needs a great potential to overcome the energy barrier to increase CO selectivity. This paper describes how 8.7 wt% gold nanoparticles...
The electrochemical reduction of carbon dioxide (CO2) is an emerging route for curbing excessive CO2 emissions and producing add‐valued chemicals. In article number 1703314, Jinlong Gong and co‐workers introduce controlled synthesis of shapecontrolled and composition‐regulatory Pd–Cu nanocatalysts by a one‐pot approach. A highly efficient performance and tunable product distribution were achieved...
Electrochemical conversion of carbon dioxide (electrochemical reduction of carbon dioxide) to value‐added products is a promising way to solve CO2 emission problems. This paper describes a facile one‐pot approach to synthesize palladium–copper (Pd–Cu) bimetallic catalysts with different structures. Highly efficient performance and tunable product distributions are achieved due to a coordinative function...
Cuprous oxide (Cu2O) photocathode is reported as a promising candidate for photoelectrochemical water splitting. The p‐type Cu2O usually forms a Schottky junction with the conductive substrate due to its large work function, which blocks the collection of photogenerated holes. NiO is considered as one of the most promising hole transfer layers (HTL) for its high hole mobility, good stability, and...
Hematite suffers from poor charge transport and separation properties for solar water splitting. This paper describes the design and fabrication of a 3D Fe2O3/Fe2TiO5 heterojunction photoanode with improved charge separation, via a facile hydrothermal method followed by atomic layer deposition and air annealing. A highly crystallized Fe2TiO5 phase forms with a distinct interface with the underlying...
