Abstract The degradation of fossil fuel and worse environmental conditions leads to the emergence hybrid semiconductor (SC) nanomaterials as photocatalysts. Hybrid SCs have interesting physical, mechanical, optical, chemical, electronic characteristics. Due these properties’ absorption light transfer charge takes place frequently hence act multifunctional surface. These materials should be attributed their optical electrical properties surfaces in energy production, generation, remediation, sensing, etc. When combine with noble, non‐noble metal, metal oxide, some carbon‐based materials, they explore wide applications various fields. Photocatalysis is an effective sustainable technology reduce or fix concerns corrosion problems. By going through extensive literature review, few topics are focused on designing working mechanisms materials. In this way, present review article explains properties, surface‐interface engineering, design, (energy environmental) nanomaterials, emphasizing photocatalytic nature. Additionally, appealing directions, scientific challenges, reasons behind poor stability SC photocatalyst for discussed. Finally, concluding remarks current challenges future prospects domain highlighted.

Toxic pollutant contamination of water resources is a significant problem. Numerous aquatic systems are tainted by various hazardous inorganic and organic species introduced wastewater from different human sources, including domestic homes, businesses, farms, mining. Given this, treating the primary environmental challenge. An overview recent advancements in materials based on graphene (Gr) for treatment given this paper. Because its special qualities, Gr, two-dimensional material with remarkable mechanical, electrical, thermal properties, has become capable applications. Here, we have discussed types Gr-based synthesis methods used to materials. The physiochemical properties materials, such as high surface area, mechanical strength, electrical conductivity, chemical stability, optical gas permeability, also been discussed. Finally, application (such removal contaminants, pharmaceuticals, heavy metals, bacteria viruses), existing challenges, future direction concluded remarks. A comparative study terms degradation performance cost compared other provided review. Therefore, comprehensive review emerging paradigm applications, providing insights into their potential impact treatment.

In this study, we aimed to evaluate the economic, environmental, and social viability of enzymatic hydrolysis process for food waste valorization by applying cost-benefit analysi (CBA). Our research was based on investigation three scenarios/alternatives final product production bioethanol, bioactive peptides, organic acids. Key economic indicators, such as cost/benefit ratios, net present value (NPV), internal rate return (IRR), were used financial performance. At end CBA, a sensitivity analysis conducted highlight performance each scenario under varying conditions, including fluctuating costs, benefits, discount rates. These results indicate that offers significant opportunity reducing its environmental impacts promotes sustainability. Bioactive peptide found be most environmentally viable option, offering highest efficiency. both optimistic pessimistic scenarios analysis, revealed is economically viable, while other alternatives, bioethanol acid production, are more sensitive operational changes. This study hydrolysis, evaluated through impactful method management. It reduces impacts, enhances sustainability, aligns with principles circular economy. The adoption innovative management strategies considered essential building sustainable resource-efficient system.

As the population increases and manufacturing grows, greenhouse gas other harmful emissions increase. Contaminated with chemicals such as dyes, pesticides, pharmaceuticals, oil, heavy metals or radionuclides, wastewater purification has become an urgent issue. Various technologies exist that can remove these contaminants from sources, but they often demand high energy and/or cost, in some cases produce contaminant laden sludge requires safe disposal. The need for methods which are less capital intensive, operationally costly more environmentally friendly is suggested. Cellulose-based materials have emerged promising candidates treatment due to their renewability, low biodegradability, hydrophilicity, antimicrobial property. In this review article, we focussed on developing sustainable biodegradable cellulose-based treatment. This article deals materials' scope conversion into valuable products like hydrogel, aerogel, cellulose composites, nanocellulose. no environmental impact plentiful. modified applying membrane, adsorbent, sorbent, beads purify were discussed.

Abstract There has been a significant scope toward the cutting‐edge investigations in hierarchical carbon nanostructured electrodes originating from cellulosic materials, such as cellulose nanofibers, available natural and bacterial cellulose. Elements of energy storage systems (ESSs) are typically established upon inorganic/metal mixtures, carbonaceous implications, petroleum‐derived hydrocarbon chemicals. However, these conventional substances may need help fulfilling ever‐increasing needs ESSs. Nanocellulose grown significantly an impressive 1D element due to its availability, eco‐friendliness, recyclability, structural identity, simple transformation, dimensional durability. Here, this review article, we have discussed role overview cellulose‐based hydrogels Additionally, extraction sources solvents used for dissolution detail. Finally, properties (such self‐healing, transparency, strength swelling behavior), applications flexible batteries, fuel cells, solar supercapacitors carbon‐based derived cellulose) devices conclusion with existing challenges updated recent findings.
