Double-Layered Sillen–Aurivillius Perovskite Oxybromide Sr2Bi3Nb2O11Br as a Fatigue-Free Piezocatalyst with Ultrahigh Hydrogen Evolution Performance
Piezocatalytic water splitting is an emerging approach for generating green hydrogen by using noise. However, while the efficiency of hydrogen production remains limited, barely anything is known about the long-term usability of the piezocatalysts. In this study, we present single-crystalline Sr2Bi3Nb2O11Br nanoplates with precise facet control and remarkable piezoelectric properties, exhibiting a significantly enhanced piezocatalytic hydrogen production rate of 5.3 mmol/g/h without needing any expensive cocatalyst, such as Pt. Furthermore, we extend the application of these nanoplates to seawater splitting with a commendable rate retention of 4.1 mmol/g/h seawater, mimicking NaCl solution and 3.5 mmol/g/h in real, unprocessed seawater, surpassing the existing piezocatalysts operated using pure water. A key finding in this work is the fatigue-resistant nature of the Sr2Bi3Nb2O11Br nanoplates originating from the layered structure. These maintain ∼100% activity for over 150 h of continuous operation, while the existing catalysts have not been tested beyond 10–15 h, offering a sustainable approach for renewable hydrogen production.
期刊介绍:
The journal Chemistry of Materials focuses on publishing original research at the intersection of materials science and chemistry. The studies published in the journal involve chemistry as a prominent component and explore topics such as the design, synthesis, characterization, processing, understanding, and application of functional or potentially functional materials. The journal covers various areas of interest, including inorganic and organic solid-state chemistry, nanomaterials, biomaterials, thin films and polymers, and composite/hybrid materials. The journal particularly seeks papers that highlight the creation or development of innovative materials with novel optical, electrical, magnetic, catalytic, or mechanical properties. It is essential that manuscripts on these topics have a primary focus on the chemistry of materials and represent a significant advancement compared to prior research. Before external reviews are sought, submitted manuscripts undergo a review process by a minimum of two editors to ensure their appropriateness for the journal and the presence of sufficient evidence of a significant advance that will be of broad interest to the materials chemistry community.
