Formic‐Acid In Situ Hydrogen Enables Programmable Ru–Pd–Pt/C Trimetallic Interfaces for Durable Acidic HER

open access: yesCarbon Energy, EarlyView.
Bamboo diaphragm−derived carbon is used as a support to prepare Ru–Pd–Pt/C catalysts through a stepwise reduction strategy. The Ru–Pd interface promotes formic acid activation and induces Pt deposition. The metallic interface of Ru–Pd–Pt/C enables H* generation, transfer, and recombination, thereby improving Pt utilization, acidic HER activity, and PEM

Revisiting Graphite Electrodes for Electric Arc Furnaces: Three‐Dimensional Microstructural Heterogeneity as a Design Parameter for Fracture Resistance

open access: yesCarbon Innovation, EarlyView.
Graphite electrodes are revisited as strategically important carbon materials for electric arc furnace steelmaking. By correlating three‐dimensional microstructural complexity with fracture energy, this work reveals a fundamental trade‐off between graphitization and energy dissipation, providing a data‐driven framework for the rational redesign of ...

Design of a Novel CeW/Fe‐TiO2 Catalyst With High Oxygen Vacancy for Enhancing the Reactivity and SO2 Resistance in Low‐Temperature NH3‐SCR Reaction

open access: yesEcoEnergy, EarlyView.
Fe3+ was introduced into the TiO2 lattice using the hydrothermal method, and low‐valent cations replaced part of Ti4+ to generate oxygen vacancies within the Fe‐Ov‐Ti unit, resulting in CeW/Fe‐TiO2 catalysts with oxygen‐deficient structures. Compared with CeW/TiO2 catalyst, the increase in oxygen vacancy content significantly improved the catalytic ...

Unprecedented Wall‐Atomically Thick Bi5O7Br Nanotubes Embedding Abundant Bi Nanodots Boosting Efficiently Photothermal Coupling Catalytic CO2 Conversion

open access: yesEcoEnergy, EarlyView.
Atomically thin Bi5O7Br nanotubes embedded with abundant Bi nanodots were constructed as an efficient photothermal catalyst for CO2 conversion. The localized surface plasmon resonance and photothermal effect of Bi nanodots synergistically enhance light harvesting, charge utilization, and reaction kinetics, resulting in significantly improved CO2 to CO ...
