Опубликована: Янв. 20, 2024

Abstract Powder‐based piezo‐catalysis, as an effective approach to degrade wastewater and produce hydrogen from water splitting, has been widely used in the field of energy conservation pollution reduction. However, these hard‐to‐recycle powders pose a challenge secondary environment. As result, this paper provides alternative strategy based on manufacture porous ceramics green chemistry replace ferroelectric currently traditional piezo‐catalysis. The piezo‐catalytic properties Ba 0.75 Sr 0.25 TiO 3 (BST) prepared using freeze casting direct ink writing techniques are investigated detail. positive effect introducing micro‐ macro‐pores is explored discovered, where BST ceramic with hierarchical pore channels by combination exhibts highest first‐order kinetic rate constant per mass catalysts, k , up 2.91 min −1 kg compared bulk ceramics. This study therefore first report for benefits average H 2 production reaching 848.88 nmol g h .

Catalysis Reviews, Год журнала: 2025, Номер unknown, С. 1 - 40

Опубликована: Янв. 8, 2025

This article presents an in-depth analysis of the current status glass-ceramics in piezocatalysis and proposes potential avenues for future research this field. Glass ceramics are a type heterogeneous material that exhibits combination properties from both glass crystalline phases. unique characteristic makes them highly versatile applicable diverse range fields. The review commences by examining historical importance as substance has been utilized since ancient times. delves deeper into various applications glass-ceramics, with specific focus on their utilization area environmental remediation. Piezocatalysis is promising technology employs mechanical energy to facilitate catalytic reactions. piezocatalysts exhibited field Prior examined photocatalytic ceramics; however, underscores dearth published studies piezocatalytic context examines efficacy glass-ceramic degrading organic pollutants purifying water, while also exploring antibacterial purposes.

Photocatalytic NaNbO₃ crystals in 60B₂O₃–30Na₂O–10Nb₂O₅ glass for dye degradation

International Journal of Applied Glass Science, Год журнала: 2025, Номер unknown

Опубликована: Март 7, 2025

Abstract NaNbO 3 crystals were fabricated in the 60B 2 O –30Na O–10Nb 5 glass system. The fabrication of parent was done via melt quench technique, and then crystallization achieved through controlled heat treatment. formation crystallites successfully observed confirmed using X‐ray diffraction Raman spectroscopy. elemental analysis present constituent glass‐ceramics performed photoemission morphological characteristics investigated field emission scanning electron microscopy (FE‐SEM). transparency samples evaluated by UV–vis spectroscopy, it has been established that transparent even after partial crystallization. Prepared used to degrade methylene blue dye photocatalysis. emergence as a photocatalyst with degradation rate 68% 240 min constant 4.5 × 10 −1 .
