Abstract

In the present study, materials based on hydrochar modified with hydrozincite were designed, varying the weight percentage of hydrozincite. The hydrozincite was prepared via a chemical co-precipitation method using thermal urea hydrolysis without any prior activation or calcination process. The hydrochar modified with hydrozincite was synthesized using a hydrothermal method at 300°C. These materials were applied in the photodegradation of contaminants. The characterization of these materials revealed that the presence of heterojunctions and oxygen vacancies plays a crucial role in the photocatalytic reaction mechanism. These materials were evaluated under UV light and a solar light simulator. The material that exhibited the highest photodegradation percentage contained 10 % by weight of hydrozincite. This suggests that these materials could be a promising alternative for the decomposition of such pollutants present in wastewater.

期刊介绍： Catalysis Today focuses on the rapid publication of original invited papers devoted to currently important topics in catalysis and related subjects. The journal only publishes special issues (Proposing a Catalysis Today Special Issue), each of which is supervised by Guest Editors who recruit individual papers and oversee the peer review process. Catalysis Today offers researchers in the field of catalysis in-depth overviews of topical issues. Both fundamental and applied aspects of catalysis are covered. Subjects such as catalysis of immobilized organometallic and biocatalytic systems are welcome. Subjects related to catalysis such as experimental techniques, adsorption, process technology, synthesis, in situ characterization, computational, theoretical modeling, imaging and others are included if there is a clear relationship to catalysis.
