Such toxicants are found in aquatic systems and can seriously ruin the water quality subsequently affecting human health and other components in the ecosystem. Aerogels are light weight porous materials that are potentially alternative of powdered nanomaterials for wastewater treatment. The aerogel-based adsorbents have found excellent properties including low density, highly stable, reusable, and easy to separate from solution. This review summaries the synthesis, and tailoring strategies of various types of aerogels for drug adsorption. The adsorption mechanisms and parameters affecting the adsorption of pharmaceuticals onto aerogels have been discussed. Freeze-drying (FD) is the most investigated method compared to supercritical drying because of its low energy consumption and consequent benefits to the environment. The aerogels based on a single material demonstrated a lower adsorption rate than the customized multifunctional hybrid aerogels. The adsorption efficiency of aerogels can be increased by chemical modifications including amination, carboxylation, and sulfonating. This review also explored the mechanistic insight of different drug adsorption onto various aerogels. Hydrogen bonding, electrostatic interaction, π-π stacking, and hydrophobic interactions, etc. are primary forces involved in the drug molecules' adsorption onto aerogels. The literature demonstrated that aerogel materials can be reused for several adsorption-desorption cycles. Furthermore, the sustainability footprint approach was utilized to assess the sustainability of nano-structured aerogels in comparison to alternative materials used for water purification.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"12 6","pages":"Article 114538"},"PeriodicalIF":7.4,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142553879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides this, it is also prominently considered as a potential candidate for new liquid fuel therefore, its production is garnering attention of scientific fraternity. However, the conventional method of producing H₂O₂ through anthraquinone oxidation is often viewed as inefficient and less environmentally friendly, as it is high energy process and generates a lot of harmful organic waste products. This review article highlights recent advancements in metal-free photocatalytic systems for sustainable production of H₂O₂. Over the last decade, significant advancement has been made in developing ecological benign protocols for the synthesis of H₂O₂ to meet UN Sustainable Development Goals (SDGs). This comprehensive review showcases key findings and refinements in metal-free light-mediated H₂O₂ production, offering promising strategies to acquire SDGs <em>via</em> more eco-friendly and cost-effective approach, utilizing only H₂O and gaseous O₂ as primary inputs and harnessing solar energy as its sustainable energy source. Nevertheless, practical applications of photocatalytic H₂O₂ production continue to face challenges such as high electron-hole (e^--h⁺) pair recombination rates, limited utilization of visible light, and suboptimal product selectivity. While progress has been achieved in improving the photocatalytic activity for generating H₂O₂, it remains primarily within the realm of laboratory research due to its currently unsatisfactory productivity levels. Given the significance of H₂O₂, we have also considered the prevailing hurdles and potential breakthroughs in photocatalytic production.
