Evaluation of Reduced-Graphene-Oxide Aligned with WO3-Nanorods as Support for Pt Nanoparticles during Oxygen Electroreduction in Acid Medium

, 2018
Hybrid supports composed of chemically-reduced graphene-oxide-aligned with tungsten oxide nanowires are considered here as active carriers for dispersed platinum with an ultimate goal of producing improved catalysts for electroreduction of oxygen in acid

Structural functionalization of TEMPO modified Ni-MOF for electrocatalytic applications

Scientific Reports
Despite their promise, the low conductivity of Metal–Organic Frameworks (MOFs) impedes their effectiveness as electrocatalysts. To address this limitation and boost electron transport and structural stability, functionalization techniques can be applied.

Unraveling the Synergistic Activity‐Stability Enhancement of a High‐Entropy Perovskite Air Electrode for Dual Ceramic Electrochemical Cells

Advanced Science, EarlyView.
A high‐entropy air electrode material, Gd0.2Pr0.2Ba0.2Sr0.2Ca0.2FeO3−δ (GPBSCF), is developed for both solid oxide fuel cells and reversible protonic ceramic cells. Its enhanced activity stems from increased oxygen vacancies/holes. The stability improvement is attributed to lattice distortion, while thermal expansion reduction is synergistically due to

Helicalization of Covalent Organic Framework Nanofibers with Amplified Spin Polarizability for Boosting Photocatalytic Hydrogen Evolution

Advanced Science, EarlyView.
A non‐covalent chirality‐induced strategy via chiral solvents is presented to synthesize helical 2D COF nanofibers with high crystallinity, high chirality, and high spin polarization. The helical structure enhances the concentration of photogenerated charges, suppresses exciton recombination, and extends carrier lifetimes, thereby significantly ...
