Elimination of dilute gaseous toluene is one the critical concerns within field indoor air remediation. The typical degradation route on titanium-based catalysts, "toluene-benzaldehyde-carbon dioxide", necessitates oxidation methyl group as a prerequisite for photocatalytic oxidation. However, inherent planar adsorption configuration molecules, dominated by benzene rings, leads to significant steric hindrance group. This prevents from contacting active species catalyst surface, thereby limiting removal under conditions. To date, no effective strategy control has been identified. Herein, we showed B-Ti-O interface that exhibits significantly enhanced efficiency In-depth investigations revealed that, compared Ti-based photocatalysts, between and surface decreased 3.42 3.03 Å designed interface. reduction originates matching orbital energy levels Ti 3d

Abstract Replacing fossil fuels by renewable biomass enables green syngas production in an effort to achieve carbon neutrality and sustainable circular processes. Here, inexpensive catalyst of Ni nanoparticles supported on SiO 2 modified La 3+ (Ni/La 0.10 –S) is presented, exhibiting exceptional H CO rates (4051.4 2467.8 mmol g −1 h , respectively) with 7.7% light‐to‐fuel efficiency cellulose steam reforming (SR), merely under focused illumination. Excellent performance mainly attributed photothermal catalysis resulting from the strong solar absorption high conversion nanoparticles. The mitigation tar char formation significantly benefits O involvement reaction, which substantially improved addition enhancing sorption. Remarkably, illumination exerts mere photoactivation during primarily pronounced activation Ni─O bonds at surface. Particularly, Ni–O–La moieties, combination species replenishment O, makes Ni/La –S superior Ni/SiO . synergy promotion Ni–O poses a promising strategy for efficient catalytic SR syngas.

The complete catalytic oxidation of propane (C3H8) at low temperatures remains challenging due to the competitive adsorption between O2 and C3H8 molecules. In this study, we propose an innovative approach enhance by strategically designing active Ptδ+ sites with modulated electronic structures on F-doped TiO2-supported Pt catalyst (Pt/F-TiO2), which exhibits 50 90% conversion 200 320 °C. Our mechanistic study reveals that electron coupling 5d F 2p alters d orbital property, leads generation abundant efficient electron-enriched species. These new facilitate promote activation chemisorbed into superoxide species, in form bridge Pt-(O–O)ad-Ti, synergistically facilitates methyl C–H cleavage C3H8. This presents strategy for structure engineering Pt-based catalysts, paving way development high-performance catalysts oxidation.
