“…Pyroelectric characteristics have been discovered in asymmetric perovskite structures, for example, lithium niobate (LiNbO 3 ), [32][33][34] barium titanate (BaTiO 3 ), [35][36][37] and lead titanate (PbTiO 3 ). [38,39] This is an appealing class of properties that convert temperature changes into current output, which is essential in the analysis of biomarkers because the current development of temperature-related detectors has hit a snag due to sensitivity limitations, whereas current recording can easily reach 10 -12 A orders of magnitude. Furthermore, the pyroelectric mechanism of pyroelectric pervoikte arises from a shift in the spontaneous polarization of certain anisotropic solids in the temperature field, which can replace the traditional Seebeckbased transducer as a new and simple core of thermoelectric generators.…”

Acute myocardial infarction (AMI) survivors face a high risk of mortality as a result of increasing heart failure and irreparable myocardial injury. New portable methods for immediate diagnosis must be developed to provide patients with daily warnings. Herein, the development of a dual‐mode photothermal‐pyroelectric output system based on a point‐of‐care platform for rapid AMI detection is reported. Termed as Integrated Photothermal‐Pyroelectric Biosensor for AMI (IPPBA), the method leverages cascade enzymatic amplification to convert the target signal into a thermal and pyrooelectric conversion of the testing process by delicate pyroelectric pervokite NaNbO3 nanocubes modified microelectrodes for sensitive detection of cTnI protein in whole blood. In addition, the mechanism of the proposed pyroelectric bioassay model is explored in depth based on in situ variable temperature X‐ray diffraction (XRD) lattice change statistics and density function theory (DFT) calculations. With standard samples and under optimized experimental conditions, the proposed IPPBA platform exhibits excellent signal stability and ultra‐low detection limit (0.05 ng mL–1) for the target cTn I. With further developments in digital technology (e.g., 5G signaling protocols, fully automated systems), the integrated digital bio‐testing platform IPPBA is fully capable of accomplishing positive and timely diagnosis of AMI.

“…In this process, pyroelectric catalysis occurs with the adsorption and desorption of shielded charge. [15][16][17][18] At present, there are more and more researches on pyroelectric materials in the field of catalysis. Sun et al have studied silicon carbide as pyroelectric catalyst, and the reactor moved alternately between hot water bath and cold water bath to ensure the cold and hot cycle at room temperature of 300-333 K. The pyroelectric properties of silicon carbide are then used to resolve hydrogen from water.…”

Doping Sr and Introducing Oxygen Vacancies in Ba_0.7Sr_0.3TiO_3‐X Synergistically Promote the Pyro‐Photo‐Electric Catalysis Performance

et al. 2022

The low utilization of light and the severe recombination of charge carriers have always restricted the development of photoelectric catalysis. In this work, the photoelectric catalytic performance is tuned by doping Sr in BaTiO 3 pyroelectric material and simultaneously introducing oxygen vacancies to form double-type defects, combined with pyroelectric polarization. Under the light and 20-50 °C cold-heat cycle, the current density of Ba 0.7 Sr 0.3 TiO 3-X reaches the maximum of 0.92 mA • cm À 2 , which is higher than the current density of Ba 0.7 Sr 0.3 TiO 3-X under only light (0.69 mA • cm À 2 ). Under light alone, the current density of Ba 0.7 Sr 0.3 TiO 3-X is higher than that of BaTiO 3 (0.19 mA • cm À 2 ) and Ba 0.7 Sr 0.3 TiO 3 (0.44 mA • cm À 2 ). This is because the incorporation of Sr can introduce the Fermi level, improve the utilization rate of solar energy, and improve the pyroelectric polarization effect with volume shrinkage, and promote the separation and transfer of carriers. Oxygen vacancies can be used as reactive centers for excited electrons to suppress the recombination of excited electron-hole pairs. Furthermore, the generation of photogenerated and pyrogenerated carriers increases the overall carrier concentration. This provides ideas for the modification of traditional photoelectrodes for photoelectric catalysis water splitting.

“…The key to achieving this goal is to find an efficient photocatalyst that is able to ideally utilize visible light, which takes %49% of the whole energy of sunlight. [10][11][12][13][14] Graphitic carbon nitride (GCN) as a non-metal organic semiconductor photocatalyst has many advantages, such as economical cost, good thermal and chemical stability, easy preparation, safety, and non-toxicity.

Graphitic carbon nitride (GCN) has become an attractive photocatalyst for solar energy conversion, but the photocatalytic activity of GCN is still limited by the extremely fast electron–hole recombination. Herein, a defective ultrathin mesoporous graphitic carbon nitride (DUMCN) photocatalyst with high specific surface area and mesoporous structure is fabricated through a facile three‐step heat‐treatment strategy, which reduces the distance of bulk photogenerated carriers to the surface, resulting in efficient adsorption and diffusion of reactants and products, and exposing adequate surface active sites. Moreover, suitable N‐vacancy defects are formed via high‐temperature surface hydrogenation, which can extend light absorption and produce ultra‐high intrinsic carrier mobility, and further increase the active sites. The photocatalytic hydrogen production rate is up to 13.63 mmol h−1 g−1 under visible light in the triethanolamine solution and 33.5 μmol h−1 g−1 for overall water splitting, which is much higher than that of bulk graphitic carbon nitride (BCN) structures. Density functional theory (DFT) calculations further reveal the effect of surface defects on the band structure for promoting the spatial charge separation. This facile strategy may offer new insights into designing other ultrathin mesoporous semiconductor photocatalysts with high performance.
