It is proposed that tetrabutyl ammonium (TBA) cations most probably intercalate into the gaps and the defects during electrochemical cycling and break the tubes near the defects.
Platinum single-atom and cluster catalysis of the hydrogen evolution reaction
A practical synthesis method to produce isolated single platinum atoms and clusters using the atomic layer deposition technique and indicates that the partially unoccupied density of states of the platinum atoms' 5d orbitals on the nitrogen-doped graphene are responsible for the excellent performance.
Single-atom Catalysis Using Pt/Graphene Achieved through Atomic Layer Deposition
Platinum-nanoparticle-based catalysts are widely used in many important chemical processes and automobile industries. Downsizing catalyst nanoparticles to single atoms is highly desirable to maximize…
Proto-calcite and proto-vaterite in amorphous calcium carbonates.
Amorphous order: Amorphous calcium carbonates (ACC) have an intrinsic structure relating to the crystalline polymorphs of calcite and vaterite. The proto-crystalline structures of calcite and vater…

Atomic layer deposited Pt-Ru dual-metal dimers and identifying their active sites for hydrogen evolution reaction
Pt-Ru bimetallic dimer structures are prepared through atomic layer deposition process and the roles of Pt and Ru in hydrogen evolution reaction are identified.
X-ray studies of the structure and electronic behavior of alkanethiolate-capped gold nanoparticles: the interplay of size and surface effects.
It is found that the lattice contracts and the d charge at the Au atom site depletes relative to bulk Au as the size of the NP decreases, suggesting the interplay of quantum-size and surface effect.
Nitrogen Doping Effects on Carbon Nanotubes and the Origin of the Enhanced Electrocatalytic Activity of Supported Pt for Proton-Exchange Membrane Fuel Cells
Carbon nanotubes (CNTs) and nitrogen-doped carbon nanotubes (CNx) were synthesized by the floating catalyst chemical vapor deposition (FCCVD) method. Pt nanoparticles were deposited onto the two…

Dopant-induced electron localization drives CO2 reduction to C2 hydrocarbons
Simulations show that the ability to tune the average oxidation state of copper enables control over CO adsorption and dimerization, and makes it possible to implement a preference for the electrosynthesis of C2 products.
