Enhancement of piezoelectric catalysis of Na0.5Bi0.5TiO3 with electric poling for dye decomposition

Jingfei Guan et al.

Summary: In this study, the performance of solid-phase sintered Na0.5Bi0.5TiO3 ceramic powder catalyst for Rhodamine B dye decomposition was investigated under different electric poling fields. The results showed that the improvement in piezoelectric catalytic activity could be attributed to the rise in the piezoelectric performance of Na0.5Bi0.5TiO3 after electric poling. Additionally, the addition of different types of radical scavengers further proved the involvement of superoxide and hydroxyl radicals in the catalytic reaction.

Defect dipole induced improved electrocaloric effect in modified NBT-6BT lead-free ceramics

Koyal Suman Samantaray et al.

Summary: The Rietveld refinement confirmed a single rhombohedral phase in 1% Fe and Mn-doped (Na0.5Bi0.5)(0.94)Ba0.06Ti0.98V0.02O3 at the Ti-site. The decrease in oxygen vacancies due to doping led to improvements in dielectric constant and adiabatic temperature difference. This was attributed to the strengthening of Bi-O and Ba-O bonds, as well as the formation of defect dipoles involving Fe, Mn, and Ti ions.

Piezoelectric catalysis for efficient reduction of CO2 using lead-free ferroelectric particulates

Pham Thi Thuy Phuong et al.

Summary: The increase in global energy demand and CO2 levels have led to research on the reduction of CO2 into useful chemicals and fuels. This paper demonstrates the piezocatalytic reduction of CO2 using lead-free lithium-doped potassium sodium niobate (KNN) ferroelectric ceramic particulates. By applying acoustic waves to a suspension of the ceramics particles, the spontaneous polarization of the KNN particles changes, creating charges for CO2 reduction.

Accelerated discovery of high-performance piezocatalyst in BaTiO3-based ceramics via machine learning

Jingjin He et al.

Summary: The study of piezocatalysis, particularly for environmental issues, has become an important topic in piezoelectric research. However, the reliance on nanofabrication poses challenges in investigating complex composition-designed materials for better performance and large-scale applications. In this work, a machine learning strategy is employed to efficiently explore the compositional space for ceramic powders with excellent piezoelectric response, aiming to improve piezocatalytic performance. (Ba0.95Ca0.05)(Ti0.9Sn0.1)O3 is selected as a promising candidate due to its relatively large piezoelectric coefficient d33 and fewer elements. The mechanically-ground ceramic powders exhibit excellent piezocatalytic activity, comparable to previously reported nanoparticles, highlighting their potential for large-scale applications.

Modulating polarization rotation to stimulate the high piezocatalytic activity of (K, Na)NbO3 lead-free piezoelectric materials

Xi-xi Sun et al.

Summary: This study reports on the modulation of polarization rotation in potassium sodium niobate (KNN) lead-free piezoelectric materials to enhance their piezoelectric properties and piezocatalytic activities. Experimental results showed that poled samples with rhombohedral-orthorhombic-tetragonal (R-O-T) coexistence phase exhibited a higher reaction rate constant. The enhanced piezocatalytic activities were attributed to easier polarization rotation and improved carrier concentration.

Piezocatalysis: Can catalysts really dance?

Franziska Bossl et al.

Summary: Piezocatalysis is an emerging area of research focused on the development of piezoelectric materials with catalytic behavior, but there is a lack of understanding of the fundamental principles behind this new catalytic phenomenon. This review highlights overlooked aspects in piezocatalysis research common in other areas like piezoelectricity, sonochemistry, and electrochemistry, discussing factors such as the nature of the mechanic field, frequency, and redox potentials of reactions that are generally ignored but critical for piezocatalysis.
