Remarkably enhanced catalytic performance in CoOx/Bi4Ti3O12 heterostructures for methyl orange degradation via piezocatalysis and piezo-photocatalysis

Ultrasonics Sonochemistry, Journal Year: 2023, Volume and Issue: 100, P. 106616 - 106616

Published: Sept. 23, 2023

A novel heterojunction composite of CoOx/Bi4Ti3O12 was synthesized through a combination molten salt and photodeposition methods. The optimal sample exhibited superior performance in the piezocatalytic degradation methyl orange (MO) dye with rate 1.09 h−1, which 2.4 times higher than that pristine Bi4Ti3O12. Various characterizations were conducted to reveal fundamental nature accountable for outstanding CoOx/Bi4Ti3O12. investigation band structure indicated formed type-I p-n structure, CoOx acting as hole trapper effectively separate transfer piezogenerated carriers. Significantly, MO best further increased 2.96 h−1 under combined ultrasonic vibration simulated sunlight. synergy between piezocatalysis photocatalysis can be ascribed following factors. photoexcitation process ensures sufficient generation charge carriers CoOx/Bi4Ti3O12, while piezoelectric field within Bi4Ti3O12 promotes separation electron-hole pairs bulk phase. Furthermore, significantly facilitates surface This involvement free electrons holes reaction leads remarkable enhancement catalytic degradation. work contributes understanding coupling mechanism effect photocatalysis, also provides promising strategy development efficient catalysts wastewater treatment.

A Comprehensive Review on the Boosted Effects of Anion Vacancy in the Heterogeneous Photocatalytic Degradation, Part II: Focus on Oxygen Vacancy

ACS Omega, Journal Year: 2024, Volume and Issue: 9(6), P. 6093 - 6127

Published: Feb. 5, 2024

Environmental problems, including the increasingly polluted water and energy crisis, have led to a need propose novel strategies/methodologies contribute sustainable progress enhance human well-being. For these goals, heterogeneous semiconducting-based photocatalysis is introduced as green, eco-friendly, cost-effective, effective strategy. The introduction of anion vacancies in semiconductors has been well-known an strategy for considerably enhancing photocatalytic activity such systems, giving them advantages promoting light harvesting, facilitating photogenerated electron-hole pair separation, optimizing electronic structure, yield reactive radicals. This Review will introduce effects vacancy-dominated photodegradation systems. Then, their mechanism illustrate how vacancy changes pathway degradation efficiency toward pollutants overall performance. Specifically, defect types methods tailoring be briefly illustrated, this part focus on oxygen (OV) its recent advances. challenges development issues engineered defects photocatalysts also discussed practical applications provide promising research direction. Finally, some prospects emerging field proposed suggested. All permission numbers adopted figures from literature are summarized separate file Editor.
