Ru Nanoparticle Supported by Mesoporous SiOx and Pillared Montmorillonite: Suppressing Catalyst Inhibition in Carbon Dioxide Hydrogenation

Chemistry – A European Journal, EarlyView.
Ru nanoparticles confined within mesoporous SiOx‐pillared montmorillonite exhibit exceptional performance for CO2 methanation. The catalyst maintains a high reaction rate even at elevated CO2 conversion while preserving high Ru mass–specific activity, overcoming typical inhibition by H2O and CO observed in conventional supported Ru catalysts.

Foil-based TiO₂/gel electrolyte/Ni_1-xO electrochromic device made of electrochromic pigment coatings

Acta Chimica Slovenica, 2014
Thin electrochromic coatings were obtained by co-grinding the mTiA particle aggregates (300 nm in size) with open-corner heptaisobutyl trisilanol POSS (T8 IB7 (OH)3 POSS) acting as dispersant. After the addition of titanium tetraisopropoxide (3-5 %) the

Heterovalent, Homometallic Rings: Synthesis, Optical, and EPR Studies of {TiIV7TiIII} Complexes

Chemistry – A European Journal, EarlyView.
A new class of heterovalent, homometallic complexes is reported, based on cyclic {TiIV7TiIII} cores with oxide and carboxylate bridges between nearest neighbors. The clusters show Class II mixed‐valent behavior at room temperature, but are valence localized at low temperature.

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

EcoEnergy, 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 ...

Lattice and Surface Engineering of Transition Metal Oxide Photoanodes for Efficient Photoelectrochemical Water Splitting

EcoEnergy, EarlyView.
This review highlights phase control, facet control, and atomic vacancy engineering as key strategies to enhance charge transport, light harvesting, and surface activity in PEC photoanodes. ABSTRACT Photoelectrochemical (PEC) water splitting is a promising approach for converting solar energy into hydrogen, yet the performance of transition metal oxide

2D/2D/2D Metallic 1T Phase WS2/TiO2/Ti3C2Tx MXene Ternary Composite for Synergistically Enhanced N2 Electroreduction

EcoEnergy, EarlyView.
TiO2 nanosheets were in situ grown on Ti3C2Tx MXene, and then 1T phase WS2 was distributed on TiO2/Ti3C2Tx MXene to form 1T‐WS2/TiO2/Ti3C2Tx MXene, which exhibits a prominent NH3 yield of 46.27 μg h−1 mg−1cat. at −0.8 V versus RHE and a superior FE of 69.26% at −0.65 V versus RHE.

Natural Anthraquinone‐Like Compound Extracted from Green Husk of Walnut Improves Photocatalytic H2O2 Production Catalyzed by TiO2 Nanoparticles

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, a novel biomolecule/semiconductor hybrid catalyst was prepared by loading anthraquinone‐liked juglone onto anatase TiO2. This catalyst exhibited high photocatalytic activity for H2O2 production. Hydrogen peroxide (H2O2) is a vital oxidant with broad industrial applications, and its production via photocatalysis represents a highly ...

Toward a Paradigm Shift in Low‐Temperature SCR Catalyst Design: Defect Engineering and Data‐Driven Integration

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work systematically reviews the key factors influencing the performance of low‐temperature NH3‐SCR. The mechanism and challenges of defect engineering strategies, such as oxygen vacancies, heteroatom doping, crystal facet exposure, and surface reconstruction, in controlling both activity and selectivity were analyzed.
