Summary
This study introduces a domino-type proton strategy for platinum single-atom catalysts (SACs) to boost hydrogen evolution reaction (HER) efficiency. The novel Pt-NC1@TiN NWs platform significantly enhances catalytic activity and stability in acidic HER.
Area of Science:
- Materials Science
- Electrochemistry
- Catalysis
Background:
- Proton engineering is key for enhancing single-atom catalysts (SACs) in hydrogen evolution reactions (HER).
- Managing proton transfer across multiple reaction steps is more effective but challenging than single-step regulation.
- Developing advanced catalysts requires novel strategies for efficient proton management.
Purpose of the Study:
- To propose and investigate a domino-type proton provision-conversion-spillover programming for Pt SACs in acidic HER.
- To design a unique catalyst platform (Pt-NC1@TiN NWs) for concerted proton management.
- To demonstrate enhanced HER performance through a cascade proton effect.
Main Methods:
- Fabrication of ultrathin porous nitrogen-doped carbon encapsulated TiN nanowires with tips (Pt-NC1@TiN NWs).
- Utilized experimental and theoretical analyses to study proton dynamics and catalytic mechanisms.
- Evaluated catalyst performance in acidic HER and proton exchange membrane water electrolyzer (PEMWE) conditions.
Main Results:
- The Pt-NC1@TiN NWs platform demonstrated a domino-type proton cascade effect, enhancing interfacial proton accessibility and intrinsic activity of Pt-N2 sites.
- Achieved a superior Pt mass activity of 153.5 A/mgPt at -100 mV, significantly outperforming commercial Pt/C.
- Exhibited excellent stability, reaching 2 A/cm² at 1.75 V and maintaining 1 A/cm² for 1200 hours in PEMWE.
Conclusions:
- The developed domino-type proton strategy effectively enhances HER performance by orchestrating multi-step proton management.
- Pt-NC1@TiN NWs show great potential as highly active and stable electrocatalysts for HER and water electrolysis.
- Harnessing multi-step domino processes is a promising avenue for designing next-generation catalysts.

44.9K
An atomic orbital represents the three-dimensional regions in an atom where an electron has the highest probability to reside. The radial distribution function indicates the total probability of finding an electron within the thin shell at a distance r from the nucleus. The atomic orbitals have distinct shapes which are determined by l, the angular momentum quantum number. The orbitals are often drawn with a boundary surface, enclosing densest regions of the cloud.

Hydrogen bonds are weak attractions between atoms that have formed other chemical bonds. One of these atoms is electronegative, like oxygen, and has a partial negative charge. The other is a hydrogen atom that has bonded with another electronegative atom and has a partial positive charge.
Hydrogen Bonds Control the World!
Because hydrogen has very weak electronegativity when it binds with a strongly electronegative atom, such as oxygen or nitrogen, electrons in the bond are unequally shared....

Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

01:24Intracellular Signaling Cascades
53.7K
Once a ligand binds to a receptor, the signal is transmitted through the membrane and into the cytoplasm. The continuation of a signal in this manner is called signal transduction. Signal transduction only occurs with cell-surface receptors, which cannot interact with most components of the cell, such as DNA. Only internal receptors can interact directly with DNA in the nucleus to initiate protein synthesis. When a ligand binds to its receptor, conformational changes occur that affect the...

Atoms — and the protons, neutrons, and electrons that compose them — are extremely small. For example, a carbon atom weighs less than 2 × 10−23 g. When describing the properties of tiny objects such as atoms, we use appropriately small units of measure, such as the atomic mass unit (amu). The amu was originally defined based on hydrogen, the lightest element, then later in terms of oxygen. Since 1961, it has been defined with regard to the most abundant isotope of carbon, atoms of which...
