Bi(Mg 0.5 Hf 0.5 )O 3 (BMH) has been frequently exploited to engineer the material’s phase structure, micromorphology, dielectric, piezoelectric, and energy storage performance of BaTiO 3 (BT)-based ceramics for the optimization of multifunctional dielectrics. Herein, combined with the Ba(Ti 0.8 Sn 0.2 )O 3 relaxor, (1 – x )Ba(Ti 0.8 Sn 0.2 )O 3 – x Bi(Mg 0.5 Hf 0.5 )O 3 (BTS- x BMH) ceramic samples were prepared through a solid-state reaction process. The micromorphology, dielectric properties, ferroelectric properties, and energy storage performance of BTS- x BMH ceramics were engineered by increasing BMH content. The addition of BMH can refine the grain size, increase the relaxation degree, raise the breakdown strength, and facilitate the production of the polar nanoregions in the BTS- x BMH ceramics. Compared to pure BTS, the energy efficiency of BTS-BMH is remarkably enhanced, which originates from the disruption of the ferroelectric long-range order owing to the BMH modification. At the maximum applied field of 100 kV/cm, the largest energy density of W rec = 0.3 J/cm 3 was realized at the composition of x = 0.05. The highest energy efficiency of η = 99% was acquired for x = 0.15 at 110 kV/cm. Moreover, the energy efficiency for x = 0.15 displays good temperature stability. These findings can guide the further optimization design of environmentally friendly BT-based ceramic capacitors for energy storage applications.

Piezoceramics with high and fatigue-resisted piezoelectric properties are strongly desired for actuator applications. In this work, textured Pb(Mg 1/3 Nb 2/3 )O 3 -Pb(Zr, Ti)O 3 ceramics with Lotgering factor F 001 ∼98% were fabricated by templated grain growth technique. Strong [001] c -grain orientation ( f ∼90% and r ∼0.22) of the textured ceramics effectively produced about 230% enhanced piezoelectric coefficient d 33 * (i.e., S max / E max ) and substantially improved unipolar electrical fatigue resistance. Unipolar polarization P max and d 33 * of the textured ceramics were nearly maintained up to 10 6 unipolar cycles, while 19% and 14% degradations were respectively observed from randomly oriented counterparts. Especially, normalized d 33 * of the textured ceramics shows better unipolar fatigue resistance than those of piezoceramics reported previously. Much lower bipolar strain asymmetry γ s (∼4%) was observed from the textured samples fatigued after 10 6 unipolar cycles as compared to γ s ∼23% for randomly oriented counterparts. While charged defect accumulation model described the serious fatigue deteriorations in randomly oriented ceramics, the current work revealed that substantially enhanced unipolar fatigue resistance of the textured ceramics is mainly associated with the inherent fatigue anisotropy, weakened local bias fields owing to both enhanced domain mobility and lower defect density near grain boundaries/interfaces, and increased intrinsic contribution due to more tetragonal content. These superior characteristics suggest the great potential of textured ceramics for high-performance and robust actuator applications.

The (1− x )BaTiO 3 – x Bi(Zn 2/3 Nb 1/3 )O 3 ( x = 0.01–0.30) ceramics were synthesized by solid-state reactions. The solubility limit was determined to be x = 0.20. A systematic structural transition from a tetragonal phase ( x ≤ 0.034), to a mixture of tetragonal and rhombohedral phases (0.038 ≤ x ≤ 0.20), and finally to a pseudocubic phase ( x ≥ 0.22) at room temperature was identified. Dielectric measurement revealed a ferroelectric ( x ≤ 0.04) to relaxor ( x ≥ 0.06) transition with permittivity peak broadening and flattening, which was further verified by Raman spectroscopy and differential scanning calorimetry (DSC). Activation energies obtained from the Vogel–Fulcher model displayed an increasing trend from ~0.03 eV for x ~ 0.05, to unusually high values (>0.20 eV) for the compositions with x ≥ 0.15. With the increase in Bi(Zn 2/3 Nb 1/3 )O 3 content, the polarization hysteresis demonstrated a tendency from high nonlinearity to sublinearity coupled with the reduction in remnant polarization and coervice field. The deconvolution of the irreversible/reversible polarization contribution was enabled by first-order reversal curve distributions, which indicates that the decreasing polarization nonlinearity with the increase in Bi(Zn 2/3 Nb 1/3 )O 3 concentration could be related with the change from the ferroelectric domain and domain wall contributions to the weakly coupled relaxor behaviors.

O3-NaNi1/3Fe1/3Mn1/3O2 has attracted much attention as a cathode for sodium-ion batteries, because of its low cost and high sodium-ion storage capacity. However, its slow Na+ diffusion kinetics and harmful P3–O3′ phase transition with severe bulk strain at high voltage leads to poor rate capability and fast capacity fading. Herein, we propose a multivariate doping strategy with Cu, Mg, and Ti ions to solve the above problems of the O3-NaNi1/3Fe1/3Mn1/3O2 cathode. The O3–Na(Ni1/3Fe1/3Mn1/3)0.9Cu0.03Mg0.02Ti0.05O2 (NFMCMT) cathode exhibits enlarged Na+ diffusion channels and a strengthened layered structure, which improves the Na+ diffusion kinetics, suppresses the harmful P3–O3′ phase transition at high voltages, and inhibits the intragranular fatigue cracks, leading to enhanced rate capability and cycling performance. As a result, the NFMCMT exhibits outstanding performance in the 2–4.1 V voltage window, delivers a discharge capacity of 151.2 mAh g–1 with the 81.5% capacity retention for 100 cycles at 0.1 C, and 83.1% capacity retention for 300 cycles at 5 C. Especially in the rate performance, the NFMCMT delivers a 115.6 mAh g–1 and 100.1 mAh g–1 discharge capacity even at 5 and 10 C. This work provides an effective multivariate doping strategy for development of high-performance layered oxide cathodes for sodium-ion batteries.

High-performance piezoelectric materials , whose displacement is sensitive to an external field and vice versa, are constantly required in electromechanical applications. Here, we introduce Nd 3+ ions into 0.49Pb(Nb 2/3 Ni 1/3 )O 3 -0.51Pb(Hf 0.3 Ti 0.7 )O 3 (PNN-PHT) ceramics via the solid-state method. By constructing a ferroelectric system in the morphotropic phase boundary region and exploiting the synergistic effect of polar nanoregions and an enhanced local structural heterogeneity, excellent piezoelectricity and dielectric properties are obtained. The optimized piezoelectric coefficient d 33 , dielectric constant ε 33 , electromechanical coupling factor k p , and dielectric loss tanδ are 1125 pC/N, 8667, 0.66 %, and 1.94 %, respectively. The Vogel-Fulcher law and relaxation analysis were adopted to understand the origin of the high piezoelectricity. The Rayleigh analysis method was used to study the intrinsic and extrinsic contributions to the piezoelectricity of the Nd-doped PNN-PHT ceramics, the extrinsic contribution was found to be up to 19 % in the optimal region (PNN-PHT + 0.4 at. % Nd 2 O 3 ). Moreover, according to in-situ ferroelectric measurements and fatigue measurements, the PNN-PHT + 0.4 at. % Nd 2 O 3 ceramic exhibits excellent fatigue resistance and stable piezoelectric behavior at 60 ℃ . This work provides an approach to realize high-performance piezoelectric ceramics with good electromechanical stability under external condition, which is expected to expand the range of application of piezoelectric materials, e.g., for transducers.

As a significant branch of cathodes for sodium-ion batteries (SIBs), the O3-type layered oxide usually receives extensive attention due to its high theoretical capacity. Due to the high tetrahedral site energy of Na+ diffusion transition state, the kinetics of the charge and discharge processes is sluggish. When the concentration of Na+ decreases, the transition metal layers undergo relative slip, leading to layer structure rearrangement and interface degradation, which result in a decrease in performance. In this work, we propose a strategy to optimize the above problem by varying the sodium content to prepare biphasic cathode materials. The prepared Na0.85Fe0.22Ni0.33Mn0.45O2 cathode has an O3/P2 biphasic structure. It shows excellent electrochemical performance, with an initial discharge specific capacity of 121.3 mAh g–1 at 0.1 C and a capacity retention rate of 94.9% after 100 cycles at 0.2 C. A small amount of P2 is introduced into the phase structure of the O3 to improve the diffusion kinetics and enhance the cycling stability. Due to the cooperative effect of O3/P2, the phase transition of O3/P2–O3/P3/P2 occurs in the electrochemical process, and the complex phase transition of O3–O’3 is inhibited. This study provides an idea for the preparation of high-performance cathode materials.

To achieve high NO oxidation efficiency, excessive O 3 must be used, which would lead to the high cost and escape of ozone. Herein, we adopted low cost and environmental-friendly TiO 2 as the catalyst of low concentration O 3 and H 2 O 2 system for high-efficiency NO x oxidation. The Ti sites on TiO 2 were the deprotonation sites of H 2 O 2 and H 2 O into Ti-OOH and Ti-OH species, respectively. We found that the surface of rutile phase TiO 2 had a low concentration Ti-OOH component but a large amount of Ti-OH after contacting with H 2 O 2 solution, thus lots of ·OH and a few O 2 − radicals formed with introducing O 3 molecules. H 2 O 2 solution induced the formation of a large amount of Ti-OOH and Ti-OH species on the anatase phase TiO 2 surface, thus lots of O 2 − generated in the O 3 /H 2 O 2 system. O 2 − and O H radicals could efficiently oxidize NO, in which O 2 − radicals could oxidize NO to NO 3 − in one step with high selectively. Therefore, anatase TiO 2 had better performance in NO x oxidation than rutile phase TiO 2 . The effect of temperature and SO 2 concentration on NO oxidation was also investigated, the results showed that TiO 2 -A/O 3 /H 2 O 2 system promoted NO oxidation at a low temperature and a low concentration of SO 2 .

The pursuit of advanced battery chemistries with enhanced energy density necessitates the exploration of new materials, a process intricately tied to synthesis science. Despite the promise of O3-type sodium oxygen anionic redox cathodes as high-capacity materials, their development has been severely hindered by a lack of understanding regarding synthetic mechanisms. Here, we elucidate the pivotal role of atmospheric conditions, particularly oxygen content, in the synthesis of such materials by synchronizing multiple operando characterization techniques to monitor changes in both solid and gaseous components. Utilizing the O3-Na[Li 1/3 Mn 2/3 ]O 2 system as a model, we demonstrate that a low oxygen environment is essential and the reaction is highly complex as evidenced by multiple oxygen uptake and release processes, resulting in numerous intermediates. This behavior contrasts sharply with Na-Mn-O and Li-Mn-O ternary systems which show less significant oxygen dynamics, underscoring the unique reaction mechanism within the Na-Li-Mn-O system. We further adopt a dynamic controlled atmosphere approach to modulate oxygen concentration and demonstrate successful synthesis of Ti-substituted NaLi 1/3 Mn 2/3- x Ti x O 2 materials, all exhibiting capacities surpassing 190 mAh g -1 . Our findings highlight the importance of the atmospheric conditions for the synthesis of oxide cathode materials and these fundamental insights unlock avenues for developing novel high-energy-density sodium-ion battery chemistries.

The degradation of polycyclic aromatic hydrocarbons (PAHs) in textile dyeing sludge by O3/H2O2 treatment was investigated. Fluorene (Fl), phenanthrene (Ph), anthracene (An) and dibenz[a,h]anthracene (DBA) were selected to represent typical PAHs. The effect of radical inhibitors, H2O2, O3 flow rate, pH and reaction time on the degradation of the four types of PAHs were examined to determine the optimal conditions for degradation and to clarify the mechanism(s) of PAHs degradation. The results indicated that the combined O3/H2O2 treatment resulted in high removal rates of the selected PAHs: 89% for Fl, 66% for Ph, 71% for An and 81% for DBA. These results correspond to the optimal conditions of an O3 flow rate of 0.4 L min−1, a H2O2 concentration of 0.60 mol L−1, a reaction time of 15 min and pH 7. The removal rate (within 30 min) increased by 5% for Fl, 27% for Ph, 21% for An and 5% for DBA through the addition of H2O2 to the O3 process. The O3 flow rate, reaction time and pH were the key parameters affecting PAH degradation with multiple interacting factors (p < 0.05) by the O3/H2O2 treatment. The degradation of the PAHs can be fitted well by pseudo-first-order kinetics (R2 = 0.9656). The combined O3/H2O2 treatment is demonstrated to be an efficient approach for the degradation of PAHs in textile dyeing sludge.

Grain size effect plays a vital role in piezoelectric performance from both scientific and technological view. However, the underlying structural mechanism related to grain size is still unclear. In the present study, the structural mechanism of grain size effect on piezoelectric performance has been revealed in the prototype Pb(Zr,Ti)O 3 system by using in-situ synchrotron X-ray diffraction. The miniaturization of grain size tends to favor the appearance of higher symmetric tetragonal phase, while a single monoclinic phase is determined in the coarse-grained ceramics. The direct structural evidence reveals that both tetragonal and monoclinic phases in the fine-grained ceramics are less sensitive to the electric field, corresponding to the inferior piezoelectric performance, while the single monoclinic phase in the coarse-grained ceramics is more active to be driven by the electric field, generating good piezoelectric behavior. Both domain switching ability and lattice strain are suppressed with decreasing grain size, which directly leads to the deterioration in piezoelectric performance. The current results will benefit the structural understanding of the size effect of piezoelectric and other related systems.

The investigation of lead-free ceramics with exceptional piezoelectric properties holds great importance in the substitution of lead-based materials, hence promoting the development of green technology and fostering an environmentally sustainable society. This study successfully synthesized two series of Bi(Mg 2/3 Nb 1/3 )O 3 (BMN)-modified BiFeO 3 –BaTiO 3 (BF–BT) lead-free piezoelectric ceramics using the conventional solid-state reaction approach. The phase structure, microstructure, dielectric, and piezoelectric properties of these ceramics were comprehensively investigated. A typical perovskite structure is observed in all probed compositions, and the associated phase structure undergoes a gradual transition from a rhombohedral-cubic phase mixture to a cubic-dominant phase structure as increases the content of BMN and BT. All compositions exhibit obvious core–shell microstructures with inhomogeneous element distributions. Most importantly, the BF–0.30BT–0.005BMN and BF–0.34BT–0.03BMN piezoelectric ceramics presented remarkable values for the piezoelectric coefficient (225 pC/N) and converse piezoelectric coefficient (396 pm/V), respectively. These findings highlight the potential of BMN-modified BF–BT ceramics for use in high-performance piezoelectric applications.
