Photocatalytic and photoelectrocatalytic H 2 O 2 production has been identified as a significant pathway within environmental pollution control, green energy, medical treatment, sterilization and disinfection. However, conventional single-material photocatalysts struggle to fulfill the stringent criteria of high efficiency, stability, cost-effectiveness, and responsiveness to visible light. The elevated recombination rates of photogenerated charge carriers, coupled with the suboptimal utilization of visible light, have collectively constrained the photocatalytic and photoelectrocatalytic H 2 O 2 production. Heterojunction catalysts for the production of H 2 O 2 has become a focal point of research. This review commences by elucidating the fundaments underlying the photocatalytic and photoelectrocatalytic H 2 O 2 production. Subsequently, it delineates the distinctive electron transfer mechanisms of Z-scheme and S-scheme heterojunctions, which exhibit enhanced efficiency in the photocatalytic and photoelectrocatalytic H 2 O 2 production, along with a summary of strategies for the improvement of photocatalyst and photoelectrocatalyst performance. Furthermore, this review also outlines the latest fabrication strategies, state-of-the-art in-situ characterization techniques, machine learning and density functional theory (DFT) simulations for Z-scheme or S-scheme catalysts for the photocatalytic and photoelectrocatalytic H 2 O 2 production, and briefly describes the multifunctional applications in H 2 O 2 production. Ultimately, the review contemplates the prospective developmental trajectories and application potential of these heterojunction configurations for the photocatalytic and photoelectrocatalytic H 2 O 2 production.

Oxide solid-state electrolytes (SSEs) are appealing as the potential substitute for conventional liquid electrolyte/separator system in lithium-sulfur batteries (LSBs). However, the poor ionic conductivity severely limits the large-scale applications of oxide SSEs in LSBs. The crystallinity of oxide SSEs is closely related to their relative density, intrinsic defects and impurities in pellets, hence playing a vital role in the ionic conductivity as well as the internal impedance and reaction kinetics of batteries. To explore the influence of the crystallinity of Li 1.5 Al 0.5 Ge 1.5 (PO 4 ) 3 (LAGP) oxide SSEs on the performance of all-solid-state LSBs (ASSLSBs), LAGP SSEs with four different crystallinity degrees are designed by regulating their preparation temperature. As a result, the LAGP with optimized crystallinity realizes the high ionic conductivity of 2.11 × 10 -4 S cm -1 , and enables the reduced internal impedance and enhanced reaction kinetics in ASSLSB, consequently delivering a high reversible capacity of 647.9 mAh g −1 even after 150 cycles at 0.1 C. The current work confirms that the crystallinity optimization is a feasible strategy to prepare better LAGP SSEs for developing future high-performance ASSLSBs. © 2022, The Authors.

Most of simulation activities implemented on semiconductor manufacturing are focus on the device characteristics, and electrical properties. Less investigation pays attention on micro-structure stress/strain calculation with finite element analysis. This investigation demonstrates the ANSYS simulation results match with real cases results. The chip-level micro-structure simulations include the metal grain size behavior influence the BEOL leakage electrical properties;different design layout causes stress concentration issue, and different collapsed behavior induced by surface tension after wet strip. The wafer-level macro-structure simulation demonstrates that different pattern density of design will affect bow height performance in whole wafer. By means of ANSYS analysis, we can achieve more experiments or DOE splits by perdition simulation instead of real wafers and experiments. Thus, we can save the cost and achieve the time-to market requirement during product development. © 2017 Taiwan Semiconductor Industry Association.

IEEE/SEMI Conference and Workshop on advanced Semiconductor Manufacturing

Subtle Ti/TiN bump defects are observed after thermal annealing in the development step of a back-end-of-line (BEOL) via metallization. It disturbs the endpoint detection of a sequential tungsten (W) chemical-mechanical planarization (CMP) process and results in W residue on the surface of the wafer. SIMS analysis conducted before Ti/TiN deposition indicates the presence of high concentrations of fluorine (F) atoms that have already doped into the oxide film after the via hole plasma etching process, even in the presence of an amorphous carbon hard-mask. The doped F species could diffuse out of the surface region, and then react with as-deposited Ti/TiN to form volatile TiF 4 during high-temperature annealing. As a result, severe metallic bump-like defects are observed. In this study, we report that the formation of the metallic bump defect is correlated to both the RF bias frequency, and the RF bias power applied in the capacitive-coupled fluorocarbon plasma via feature etching.

Using an axial feeding dc-plasma spray gun for fabrication of ceramic coatings

Ceramic Transactions

Ceramic Transactions 2018年 263卷 479-490页

Thermal DC-plasma spray is widely used technology for fabrication of ceramic coatings with high deposition rates and relatively low cost. The process is based on supplying the feedstock powder material into a very high temperature plasma jet, where it is rapidly heated and accelerated with a high velocity. The molten or semi-molten particles collide on the substrate surface and rapidly solidify. Then the accumulated particles form a coating. Generally the powder can be injected either from inside the nozzle of the plasma torch (axial or internal injection) or at a very short distance downstream of the plasma torch exit (radial or external injection). The axial injection has the unique advantages of precise location of the powders and more inclusive heating of the particles. Therefore it can be fully entrapped inside and melted within the plasma before being deposited on the substrate surface. This study will show our efforts of developing a new DC-plasma spray system using axial feeding for fabrication of ceramic coatings. New suspension plasma spraying system was developed using the twin cathode plasma spray gun. The system enables the axial injection of the fine particles with using only Ar gas plasma gas (gas consumption) under low working power. The axial feeding is promising in case of using the nano-size particles in the form of suspension. Thus, the liquid suspensions are injected directly into the core zone of the plasma (the highest heat and momentum transfers are between the plasma and feedstock suspension). Therefore, the stream and the drops are introduced directly into the hot gases and are rapidly fragmented in tiny droplets (a few micrometers in diameter). These tiny droplets are then vaporized to form the molten droplet and then deposit on the substrate. Furthermore, the axial injection of the suspensions makes the injections issues simple. Thus, the suspension is directly injected into the center of the plasma jet and therefore avoids the more turbu

Theoretical Study on the Adsorption and Hydrogenation Mechanism of 2-Methylthiophene over the Pt(111) Catalyst

引用

Chinese Journal of Structural Chemistry 2017年第12期36卷 1961-1974页

The adsorption process and hydrogenation mechanisms of 2-methylthiophene on the Pt（111） surface have been elucidated using density functional theory（DFT）. The optimal adsorption sites of reactants, intermediates, and products as well as the activation energy and reaction energy of each elementary reactions were investigated. The results turned out that the 2-methylthiophene tilt to the Pt（111） catalyst with the C_1–C_2 double bond at the top site was the most stable. During the hydrogenation process, the heat of reaction almost located at the negative side, so dropping the temperature is good for the occurrence of hydrogenation process. The hydrogenation steps of mechanism take place along C_2→C_3→C_1→C_4→S→C_1 to generate the product of pentane-2-thiol, in which the first step with the highest energy barrier is the rate-determining step.
