The controlled disassembly of mesostructured perovskites as an avenue to fabricating high performance nanohybrid catalysts

Disassembly of three-dimensionally ordered materials generates nanoparticles with new structural and physicochemical properties. Here the authors show a fragmentation strategy applied to a perovskite material leading to nanostructures with improved catalytic activity in the methane combustion.

A single-Pt-atom-on-Ru-nanoparticle electrocatalyst for CO-resilient methanol oxidation

PtRu nanoparticles are the state-of-the-art catalysts for methanol electrooxidation—the anodic reaction in direct methanol fuel cells. Now, a method of dispersing single Pt atoms over Ru nanoparticles is presented and monitored in situ, thereby boosting the catalytic performance in the methanol oxidation reaction.

Single-phase perovskite oxide with super-exchange induced atomic-scale synergistic active centers enables ultrafast hydrogen evolution

Efficient electrocatalysts are crucial for the sustainable hydrogen production as an alternative clean fuel. Here, the authors explore a single-phase perovskite oxide as a high-performance hydrogen evolution electrocatalyst via super-exchange induced atomic scale synergistic active sites.

Unusual synergistic effect in layered Ruddlesden−Popper oxide enables ultrafast hydrogen evolution

Water may serve as a renewable hydrogen fuel source to replace fossil fuels, although such electrolysis requires highly active catalysts. Here, authors explore Ruddlesden−Popper oxides as hydrogen evolution electrocatalysts that feature an unusual synergistic effect to promote high activity.

Metallicity at interphase boundaries due to polar catastrophe induced by charge density discontinuity

We introduce a mechanism that can result in metallicity at stoichiometric interphase boundaries between semiconductors, based on the idea of polar catastrophe induced by charge density discontinuity. As an example, we demonstrate metallicity at the stoichiometric (110) interphase boundary of the semiconductors SnO and SnO₂. The proposed mechanism is of general validity and expected to have an important role at interphase boundaries between polar materials.
