Abstract
Efficient catalytic conversion can be achieved by electro-mechanical coupling and solar energy-induced photogenerated carriers. In this work, an advanced semimetal Bi decorated Bi4Ti3O12 (Bi/BTO) heterojunction catalyst was constructed through in-situ reduction without organic solvent. The piezo-photocatalytic removal toward MB of Bi/BTO catalyst reaches 87.2% within 70 min, and the rate constant is 2.23 and 1.80 times higher than that of piezocatalysis and photocatalysis, respectively. The enhanced performance is attributed to not only surface plasmon resonance effect of Bi nanoparticles that enhances light absorption and accelerates charge separation, but also the piezoelectric effect of Bi4Ti3O12 which strengthens internal electric fields. Moreover, the metal titanium template can be recycled to synthesize Bi/BTO catalyst, thus favouring commercial-scale application. This work demonstrates an effective strategy to design efficient catalyst to utilize natural solar and mechanical energy.
期刊介绍:
The aim of the journal is to provide a respectful outlet for ''sound science'' papers in all research areas on surfaces and interfaces. We define sound science papers as papers that describe new and well-executed research, but that do not necessarily provide brand new insights or are merely a description of research results.
Surfaces and Interfaces publishes research papers in all fields of surface science which may not always find the right home on first submission to our Elsevier sister journals (Applied Surface, Surface and Coatings Technology, Thin Solid Films)
