Close-Contact Oxygen Vacancies Synthesized by FSP Promote the Supplement of Active Oxygen Species To Improve the Catalytic Combustion Performance of Toluene.

Catalytic combustion is an important means to reduce toluene pollution, and improving the performance of catalytic combustion catalysts is of great significance for practical applications. The study of oxygen vacancies is one of the key steps to improve catalyst performance. Here, two different oxygen vacancy structures were well-defined and controllably synthesized by flame spray pyrolysis (FSP) to evaluate their effect on the catalytic combustion performance of toluene.

Photocatalytic degradation of dyes by novel electrospun nanofibers: A review.

Textile industry is a significant contributor of wastewater, which contains pollutants including dye and other chemical substances. The release of thousands of tons of dye used in textile processing and finishing into natural streams and aquatic bodies present dire harm to the environment. In response to environmental concerns, a number of research have been done using low-cost technology to produce absorbents that can remove dyes from water bodies.

Highly efficient Au/FeO for CO oxidation: The vital role of spongy FeO toward high catalytic activity and stability.

Supported gold catalysts have drawn great attention for many decades due to their outstanding performance in remedying the environment from carbon monoxide (CO) pollution. In this study, due to the large surface area of spongy FeO, fabricated by salt-assisted ultrasonic spray pyrolysis, a considerable amount of Au was loaded on spongy FeO compared to low-surface-area non-spongy FeO. It is seen that the spongy FeO catalyst loaded with Au has an interface that can be extremely active for CO desorption and O activation.
