The drawbacks of hydrogen are thoroughly examined in this article, including production-related carbon emissions and security issues. To overcome these obstacles and realize a hydrogen-based economy that contributes to sustainable development objectives and mitigates climate change, interdisciplinary partnerships, legislative interventions, and technological developments are required. Moreover, numerous hydrogen production techniques are discussed, including standard and unconventional ways. In terms of unconventional methods, photocatalytic water splitting stands out as a cutting-edge innovation that makes use of nanomaterials as catalysts to collect solar energy and fuel the water-splitting reaction. The review focuses on the synthesis, characterization, and hydrogen production efficiency of current developments in photocatalytic materials. A thorough overview of hydrogen generation techniques is provided, mainly focusing on photocatalytic water-splitting using nanomaterials. It offers valuable insights for academics, policymakers, and stakeholders looking to promote the integration of hydrogen into a sustainable energy landscape by looking at the color coding of hydrogen production, storage systems, hydrogen utilization, and related issues.","PeriodicalId":639,"journal":{"name":"Journal of Inorganic and Organometallic Polymers and Materials","volume":"40 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2024-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141881231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rGO-ZnO-EPs composite was synthesized using a straightforward chemical route, followed by extensive characterization to elucidate its structural and electrochemical properties. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) analyses confirmed the successful incorporation of ZnO nanospheres and EPs into the rGO matrix, forming a highly porous and well-integrated composite structure. Electrochemical performance assessments revealed that the rGO-ZnO-EPs composite exhibits a high specific capacitance of 535 F/g at a current density of 1 A/g, significantly surpassing traditional electrode materials. Notably, the composite demonstrated exceptional cyclic stability, retaining 90% of its initial capacitance after 3000 charge-discharge cycles, indicative of its robust long-term stability. Further analysis using electrochemical impedance spectroscopy (EIS) indicated low electrical resistance, which facilitates enhanced ion diffusion and surface charge transfer processes. This low resistance, combined with the high surface area and abundant active sites provided by the porous structure of ZnO nanospheres, contributes to the superior electrochemical performance of the rGO-ZnO-EPs composite. These findings emphasize the potential of the rGO-ZnO-EPs hybrid composite for advanced energy storage applications, particularly in supercapacitors, where high capacitance, excellent cyclic stability, and efficient charge transfer are critical.

PLA is widely used in additive manufacturing, especially in biomedical applications, due to its biodegradability and biocompatibility. However, its interaction with biological tissues can be improved. ZnO was chosen for its wound-healing properties, while keto, a nonsteroidal anti-inflammatory drug, was selected to provide local anti-inflammatory effects. PLA filaments were prepared by incorporating ZnO and keto, followed by analyses of their mechanical, thermal, and biological properties. The results showed that the incorporation of ZnO and keto did not compromise the mechanical and thermal properties of the PLA filaments. Compared to pristine PLA, the composites presented a slight improvement in strength. The incorporation of ketoprofen in the composite increased its thermal stability compared to PLA-ZnO filament. Concerning the morphology, when ZnO and Keto were inserted, the scaffold acquired a more robust structure, with well-defined porosity. In vitro biocompatibility tests indicated that the modified filaments exhibited lower cellular toxicity and improved cell adhesion and proliferation compared to pure PLA. Antimicrobial tests demonstrated that the filaments containing ZnO, at the evaluated concentration, did not exhibit activity against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa, gram-positive and gram-negative bacteria. The combination of ZnO and ketoprofen in PLA filaments can enhance their biomedical applications, providing better biocompatibility without compromising the intrinsic characteristics of PLA.
