Phase‐Stable Palladium Hydride Derived from PdCoO2 for Sustainable Hydrogen Evolution Reaction

open access: yesAdvanced Functional Materials, EarlyView.
The exceptionally active β‐PdHx is demonstrated for the hydrogen evolution reaction in acidic media. The fast activation kinetics from the PdCoO2 template are resolved by operando spectroscopy, and isotope‐labeled atom probe tomography quantifies the H content in β‐PdHx. The outstanding stability of the electrocatalyst is attributed to the retention of

PbCrO4/Pb Hybrid with Surface Unsaturated Metal Sites for Efficient CO2‐to‐Formate Reduction

open access: yesAdvanced Functional Materials, EarlyView.
An in‐operando electrochemically synthesized Vo‐rich PbCrO4/Pb hybrid exposes abundant unsaturated metal sites on PbCrO4 surface, which facilitates CO2 activation and stability of *OCHO intermediates. Simultaneously, the bulk Pb nanorod significantly enhances the conductivity of electrode for fast charge transport. The Vo‐rich PbCrO4/Pb electrocatalyst

Harmonizing the Pyrene and Ether Groups in Covalent Triazine Polymers for Highly Effective H2O2 Photosynthesis via One‐Step Two‐Electron Oxygen Reduction

open access: yesAdvanced Functional Materials, EarlyView.
The pyrene and ether groups are incorporated into the covalent triazine polymer (CTP) structure. The synergistic effect of the two functional groups endows CTP with better electron transfer, light absorption, and oxygen activation properties. An impressive apparent quantum yield (13.2% @420 nm) and a remarkable solar‐to‐chemical conversion efficiency ...

An Introduction to Programming and Proving with Dependent Types in Coq

open access: yesJournal of Formalized Reasoning, 2010
Computer proof assistants vary along many dimensions. Among the mature implementations, the Coq system is distinguished by two key features. First, we have support for programming with dependent types in the tradition of type theory, based on dependent ...
