Bubble induced piezoelectric activation of peroxymonosulfate on BiOCl for formaldehyde degradation during the absorption process: a density functional theory study

“…As a new catalytic technology, piezoelectric catalysis produces electric charges on the surface of piezoelectric materials by means of minute mechanical vibrations and then generates active groups such as HO˙ and superoxide radical (O 2 ˙ − ) to assist catalysis. 27–29 Currently, it has been applied in many fields, such as in the degradation of aqueous organic pollutants. For example, Lan et al 30 and Liu et al 31 found that the coupling of the piezoelectric effect and PMS activation can greatly improve the degradation efficiency of benzothiazole and phenol.…”

Comprehensive review of micro/nanostructured ZnSnO3: characteristics, synthesis, and diverse applications

“…Accordingly, to overcome this limitation and improve their characteristics, researchers are actively engaged in the development of ternary oxides, such as ZnSnO 3 and In-Zn-O. [5][6][7] Among them, nanostructures of ZnSnO 3 (various nano shapes, such as wires, rods, rings, tubes, cubes, and spheres) have attracted considerable interest owing to their advantageous chemical sensitivity, wide energy bandgap, high transmittance percentage, electron mobility, low price, non-toxicity, and earth abundance. 5,[8][9][10][11][12][13] The performance of energy storage devices and catalysis is greatly affected by the morphology, structure, and physical characteristics of the active electrode materials.…”

Flexible Hybridized Nanogenerators Based on a Reduced Graphene Oxide Nanosheet-Decorated Piezoceramic Skeleton to Impact Mechanical and Thermal Energy Harvesting

“…However, the nonconvenience caused by regular replacement and the environmental pollution caused by waste after use put forward an urgent need for new energy solutions to replace chemical batteries . For a polar material, the spontaneous polarization ( P s ) can be modulated by an external force field and/or temperature field to show piezoelectric effect and pyroelectric effect independently or simultaneously; thus, it can be used as an energy harvester to scavenge waste mechanical energy and thermal energy in the environment to achieve clean power generation. , Meanwhile, in recent years, catalytic applications related to polar materials have attracted wide attention, and some important achievements have been reported. − As representative polar materials, ferroelectric ceramics such as BaTiO 3 (BT) and Pb­(Zr,Ti)­O 3 (PZT) have excellent piezoelectric and pyroelectric properties. , However, due to their inherent rigidity and brittleness, they cannot be used as energy harvesters to match wearable electronic devices. In contrast, the ferroelectric polymers represented by polyvinylidene difluoride (PVDF) and polyvinylidene fluoride-trifluoroethylene (P­(VDF-TrFE)) have the advantages of flexibility and good machinability, but the weak piezoelectric properties and poor thermal conductivity affect their application as a piezoelectric or pyroelectric energy harvester. − By introducing low-dimensional ferroelectric particles into an organic polymer, the formed piezocomposites can combine the merits of both materials; thus, the derived flexible hybridized nanogenerators (FHNGs) have become a research hotspot in the field of energy harvesting. − It should be noted that for piezocomposites, the ferroelectric filler is the main contributor to piezoelectric and pyroelectric effects, and the polymer is mainly used as the matrix to ensure flexibility .…”
