【Piezoelectric Field and TENG Co-Promoted Photocatalytic Degradation of HCHO on BaTiO3/g-C3N4/PTFE/Cu for Self-Cleaning and Air-Purification】 Applied Catalysis B: Environment and Energy (IF 20.2) Pub Date : 2024-11-24 , DOI:10.1016/j.apcatb.2024.124859 Photocatalysis represents a powerful way for air purification. The key problem is how to design powerful and stable photocatalysts. This work developed a novel triple functional BaTiO3/g-C3N4/Polytetrafluoroethylene (PTFE) /Cu photocatalyst. The wind-induced piezoelectric field from BaTiO3, together with the BaTiO3/g-C3N4 heterojunctions, facilitated the separation of photoelectron-hole pairs. Meanwhile, the wind-generated surface charges via triboelectric nanogenerator (TENG) from PTFE/Cu film promoted the formation of ·O2- and adsorption of formaldehyde (HCHO) via electrostatic attraction. As a result, the as-prepared BaTiO3/g-C3N4/PTFE/Cu thin film exhibited high activity in degradation of trace HCHO in air under wind blowing and sunlight irradiating, which was 1.5 times higher than pure g-C3N4. Moreover, it also displayed strong stability against leaching owing to the PTFE, leading to a long lifetime during photocatalysis. By spraying films of piezoelectric photocatalysts on car and train surfaces, this study provides an efficient and durable strategy for self-cleaning and air-purification under sunlight-irradiation and wind-blowing. https://lnkd.in/ep45WAPG

𝐒𝐜𝐢𝐞𝐧𝐭𝐢𝐬𝐭𝐬 𝐝𝐞𝐯𝐞𝐥𝐨𝐩 𝐡𝐲𝐝𝐫𝐨𝐠𝐞𝐧 𝐟𝐫𝐨𝐦 𝐚𝐥𝐮𝐦𝐢𝐧𝐮𝐦, 𝐬𝐞𝐚𝐰𝐚𝐭𝐞𝐫 𝐚𝐧𝐝 𝐜𝐚𝐟𝐟𝐞𝐢𝐧𝐞 Scientists from #MIT have demonstrated a way to produce hydrogen using recycled aluminum cans, seawater and caffeine. The study is published in the journal Cell Reports Physical Science and details how the processed aluminum interacts with seawater salts to produce hydrogen gas. This happens without the formation of a protective oxide film, which normally interferes with the reaction. Adding caffeine, particularly its active component imidazole, speeds up the hydrogen production process by a factor of 5. Based on this, the team created a compact reactor... https://lnkd.in/dResa5qG #archtown #science #greenenergy

Anew material that converts sunlight and water into clean energy has been developed by scientists. The photocatalyst created by researchers at Oregon State University enables the high-speed, high-efficiency production of hydrogen. The collaboration led by Kyriakos Stylianou of the OSU College of Science represented the potential new tool to use against greenhouse gas emissions and climate change. Stylianou’s research focuses on crystalline, porous materials known as metal organic frameworks, usually abbreviated as MOFs. Researchers tested multiple RTTAs with different amounts of the oxides In this study, researchers used an MOF to derive a metal oxide heterojunction – a combination of two materials with complementary properties – to make a catalyst that, when exposed to sunlight, quickly and efficiently splits water into hydrogen. The heterojunction, which they refer to as RTTA, features MOF-derived ruthenium oxide and titanium oxide doped with sulfur and nitrogen. They tested multiple RTTAs with different amounts of the oxides and found a clear winner, according to Oregon State University https://lnkd.in/dpVzxyWG #Green hydrogen #Catalysts #Metaloxides

Are you interested in unlocking new pathways for sustainable, eco-friendly energy solutions based on biosourced materials?  Our latest article reports on the potential of using polyphenols as green materials for energy storage devices. Through a systematic electrochemical study, we evaluated the performance of several polyphenols with similar molecular structures as organic electrodes for supercapacitors. Our studies include the interface engineering of polyphenol-modified carbon paper electrodes, the effect of monovalent/multivalent cations on the electrochemical behavior of polyphenols, charge transfer kinetics, and relationships between their (supra)molecular structure-electrochemical properties.

Exploring Zinc Vanadate/Cobalt Oxide (Zn3(VO4)2/CoO) Nano Hybrid Composites as Supercapacitors for Sustainable Energy Storage Applications A hybrid nanocomposite of zinc vanadate/cobalt oxide (Zn3(VO4)2/CoO at ratios of 90/10, 80/20, 50/50, and 20/80) was obtained using a simple co-precipitation technique, then calcinated for 4 hrs at 400°C. The surface morphological, vibrational, and structural characteristics of the synthesized hybrid nanocomposites were examined. According to the structural study, orthorhombic Zn3(VO4)2 and cubic crystal systems of CoO with space groups Fm-3m were formed. The functional groups of Zinc Vanadate/Cobalt Oxide were examined using FTIR spectroscopy. A scanning electron microscopy (SEM) study reveals the nanosheets structures with the size of 200 nm. The chemical composition and formation of the Zn3(VO4)2/CoO composites were confirmed using X-ray photoelectron spectroscopy (XPS). The electrochemical performance of the hybrid nanocomposites was assessed through CV, GCD and impedance analysis. Among the nanocomposites, Zn3(VO4)2/CoO 80/20 exhibited a high specific capacitance value of 564.36 Fg-1 and retaining 97% of their total capacitance even after 3000 cycles. #ZincVanadate #CobaltOxide #Supercapacitor #Energystorageapplications #Research #MaterialScience #Innovation #Journal #Publication #Scopus #OpenAcess #Environment #Engineering #Scientific #Science #Study #R&D Read more https://lnkd.in/gZu8ZECE        For more information, please read our recent articles at https://lnkd.in/gqaMY-sW
