A Ti/Cu laminated electrode with a slot width of 250 µm is fabricated by explosive welding and an electrochemical corrosion process is applied to create groove-shaped interface. The results show that the grooved laminated electrode has superior hydrogen precipitation performance and conductivity, exceptional stability, and minimal potential fluctuation. Hydrogen production efficiency of laminated electrode is 120% higher than that of Cu electrode, which is verified in our self-made hydrogen-making device.

However, the long channel length of conventional planar structures, usually in the micron range, greatly reduces the carrier transport efficiency and leads to an increased probability of defect trapping and complex recombination of photogenerated carriers. Here, an organic phototransistor with a vertical channel structure has been demonstrated, in which the active layer is blended with Mxene. Due to the short channel length of vertical structure, the recombination possibility of photogenerated excitons is reduced, and the high ultraviolet sensitivity of Mxene increases the bandwidth of detection. The device exhibits excellent photodetection performance with the photosensitivity of 4.28 × 106, photoresponsivity of 2.39 × 104 A/W, detectivity of 1.04 × 1017 Jones under irradiation with weak light of 8 μW cm−2 at 365 nm.

For electronic properties, we have studied the band profile, density of states, and electronic density of RFeO3. The band profile of RFeO3 comes out to be half-metallic in mBJ + U. Further, optical properties have been computed corresponding to photon energy (0–10 eV). Thermodynamic examination of these compounds is performed using the Quasi-Harmonic Debye model. Consequently, the thermodynamic parameters' variation has been examined with temperature (0–1200 K) as well as pressure (0–40 GPa). Finally, we have evaluated the thermoelectric parameters using BoltzTrap code, and their variation with temperature (50–1200 K) and chemical potential (−2 to 2 eV) has been presented. We have obtained a maximum thermoelectric efficiency of 0.38 for PrFeO3 perovskite, and it is found that it increases with temperature.

Here, this study reports a novel class of adsorbents Metal Organic Framework (MOF) and its g-C3N4 based composites are used to adsorb CO2. The synthesis of Ni-BDC MOF and its 1–8 wt% g-C3N4/Ni-BDC MOF composites were successfully prepared via the solvothermal method. These samples are characterized by using different techniques like XRD, EDX, SEM, FTIR to investigate the structural and morphological properties. The MOFs and their composites were studied for CO2 adsorption and desorption at a temperature of 25 °C and 0–15 bar pressure. Among all the composites, 5 wt% g-C3N4/Ni-BDC MOF shows the highest adsorption capacity of 0.50 mmol/g. The rising adsorption trend of all prepared materials shows that these samples do not reach their saturation point and can still adsorb more CO2 even at pressure higher than 15 bar.","PeriodicalId":501486,"journal":{"name":"Materials Science and Engineering: B","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138535652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
