Adaptive Catalytic Nanointerfaces for Controlled Hydrogen Evolution: an in Situ Electrochemical Approach

Advanced Science, EarlyView.
The ability to switch the HER activity of precious metals at will through a reconfigurable step‐edge/nanoparticle interface, using sulfur as an inorganic mediator, is demonstrated for the first time. This methodology addresses the durability issue of highly catalytic precious metals, which are typically single‐use, thereby extending their lifespan ...

Designer Electrocatalysts for the Oxygen Reduction Reaction with Controlled Platinum Nanoparticle Locality

Advanced Energy Materials, EarlyView.
Pt/C catalysts differing only in the locality of the Pt nanoparticles, whether inside or outside of the pores of the same carbon support, are needed to study the effect of said locality. Depending on the carbon support used, nanoparticles inside the pores can show hindered accessibility and ORR performance.

Impact of Transition Metals and Electrocatalyst Layer Thickness on the Pt‐Based Cathodes of Proton Exchange Membrane Fuel Cells – Do Multimetallic Electrocatalysts Necessarily Yield an Improved Performance?

Advanced Energy Materials, EarlyView.
Nonnoble transition‐metals (TMs) in PtCuNi/C catalysts have a dual influence in proton‐exchange membrane fuel cell cathode catalyst layer. While TMs act as a “sacrificial component” of PtCuNi/C, inhibiting Pt dissolution from the PtMx nanoparticles bearing the active sites, they promote the formation of separate catalysts and ionomer domains in the ...

Toward Understanding the Stability of Single‐Atom Catalysts in Oxygen Evolution Reactions

Advanced Energy Materials, EarlyView.
Enhancing the stability of single‐atom catalysts for the oxygen evolution reaction hinges on understanding support interactions, local geometry, and structural dynamics. Transitioning to OH‐modified surfaces offers a promising route to cap surface metals and prevent leaching, paving the way for the next generation of stable OER SACs.

Degradation of NiMo Catalyst Under Intermittent Operation of Anion Exchange Membrane Water Electrolyzer and its Mitigation by Carbon Encapsulation

Advanced Energy Materials, EarlyView.
Herein, by employing a reference electrode, the durability of anion exchange membrane water electrolyzer (AEMWE) under intermittent condition is demonstrated to be governed by the stability of the cathode catalyst. By encapsulating NiMo catalyst with carbon shells, the oxidation‐induced irreversible transformation to inactive hydroxide is prevented ...

Food waste, date labels, and risk preferences: An experimental exploration

Applied Economic Perspectives and Policy, EarlyView.
Abstract This study provides theoretical and experimental evidence that consumers adjust their premeditated food waste by date labels and their risk and loss preferences. The “Use by” date label leads to more premeditated food waste than “Best by” for deli meat and spaghetti sauce.
