Electrochemically Induced Oxide‐to‐Hydroxide Transformation Enables Fast Proton Transport for Enhanced Hydrogen Evolution

Advanced Science, EarlyView.
An electrochemically induced transformation of polar MgO(111) into Mg(OH)2(001) creates a proton‐conductive hydroxide layer during hydrogen evolution. Operando synchrotron XRD and DFT reveal a low‐barrier Grotthuss proton‐hopping mechanism, establishing a feasible strategy for designing oxide‐hydroxide electrocatalysts with enhanced proton transport ...

Densification of expanded graphite

Carbon, 2002
A brief theoretical investigation of the behavior of exfoliated graphite (EG) undergoing compaction is presented. Simple arguments and assumptions allow one to calculate the density of the initial individual worm-like particles of EG for any final porosity of the resultant consolidated blocks. These results as well as excluded volume considerations are

Graphite foam from pitch and expandable graphite

Carbon, 2014
Graphite foams were prepared from a coal tar pitch that was partially converted into mesophase. Expandable graphite was used instead of an inert gas to "foam" the pitch. The resulting foam was subjected to a series of heat treatments with the objective of first crosslinking the pitch, and thereafter carbonizing and graphitizing the resulting foam.
