To address this issue, a new highly stable, greener, nontoxic composite material (ZBH.Sn) consisting of Sn<sup>2+</sup> doped Zn-Bi mixed metal hydroxide (ZBH) was effectively fabricated. The adsorbent underwent a thorough investigation of its structural and morphological properties utilizing XRD, HR-TEM, FE-SEM, FTIR, XPS, Zeta, and DLS. XRD confirms the crystallinity of mixed phases of both zinc and bismuth hydroxides. The hexagonal sheet-like morphology is evident in SEM, and elemental mappings show that individual elements are evenly distributed on the external surface. The ZBH.Sn adsorbent demonstrates an adsorption efficiency in the removal of Fuschin blue (F.B.) from wastewater systems. With optimized 2.5 mg ZBH.Sn in 20 mL (0.05 mM) of F.B concentration at pH 6, the maximum adsorption capacity was 80.56 % in 180 minutes at 298 K.

Recently, Metal-organic frameworks (MOFs) have attracted attention as a prominent class of porous materials with robust topology and excellent potential in photocatalytic water remediation applications. Numerous literatures have reviewed the photocatalytic activity of MOF-based materials for environmental and energy applications. However, only a few articles focus on the pioneering role of MOF-5, a Zn-based MOF in growing contemporary applications. Moreover, a review focused primarily on MOF-5 photocatalysts – their synthesis, application, and detailed mechanism studies for the removal of toxic organic pollutants from an aqueous medium has not been made. In this review, we summarized the recent advances in MOF-5-based photocatalysts and their application in the photocatalytic of dye pollutants from an aqueous medium. The fundamental structure and principle of MOF-5 as a photocatalytic material have been discussed. The various synthesis methods employed for the preparation of MOF-5-based photocatalysts have been discussed. This article compiles and reviews the recent advancements in utilizing MO-5-based materials for the photodegradation of dyes from water. The detailed analysis of the literature revealed that the MOF-5 photocatalysts demonstrate excellent photocatalytic performance toward the elimination of organic dye pollutants such as methylene blue, rhodamine B, congo red, and methyl orange from an aqueous medium. Furthermore, an overview of the general mechanism and pathways observed in the photodegradation of dyes using MOF-5 has also been provided.

Given the huge demand for green hydrogen to decarbonize the energy sector and chemical industry, the global supply of metal catalysts has become a large concern. In this context, atomically dispersed catalysts (ADCs) have been proposed to be a promising alternative to the conventional nanoparticulate catalysts, enabling maximal utilization of metals and in the meantime good OER performance in the aqueous solutions of both alkali and acid. In view of huge potential application in the OER as well as water splitting, well-designed ADCs composing of transition metals (iron, cobalt or nickel) or noble metals (ruthenium or iridium) as active sites are summarized firstly in the current review. Next, the powerful tools in the investigation of structure-performance relationship and OER catalytic mechanism have been elaborated, including various <em>in-situ</em> characterizations and theoretical calculation. Finally, some challenges and perspectives for future development of ADCs are also listed, such as increasing the apparent activity, operation stability as well as possible device performance verification.

There are also substantial political and technical risks which can prevent timely mitigations.

Such revenues are not possible without assessing the baseline emissions, the forest reference emission level (FREL), and the effectiveness of the REDD+ activities. This study aimed to assess the carbon emission reductions from reducing deforestation, carbon removals from enhancing forest carbon stocks, and carbon revenues in the Vavuniya district, Sri Lanka by assessing baseline emissions and FREL (2001 – 2020) in dry monsoon forest using the Google Earth Engine and the phenology-based threshold classification. The Vavuniya district is one of the war-affected dry zone districts showing a significant loss in forest cover. This study considered the carbon pools aboveground, belowground biomass, and litter to calculate forest carbon stocks since a significant change can be observed in these pools due to forest loss. The estimation shows that the annual depletion of carbon stocks was 45,083.6 MgC between 2001 and 2020, which accounts for the total carbon emissions of 165,306.6 MgCO<sub>2</sub>. FREL established for the period of the Paris Agreement was at 155,187.9 MgCO<sub>2</sub> yr<sup>−1</sup>. Around 94,331.0 MgCO<sub>2</sub> of annual carbon emissions could be reduced if REDD+ actions are implemented between 2020 and 2030. While annual carbon removals from the open forest could be 7731.5 MgCO<sub>2</sub>. Based on the carbon price selected at the voluntary carbon market and the European Union emission trading system, total emission reductions and removals can be equivalent to carbon revenues ranging from approximately USD 7.3 million to USD 87.5 million. These revenues are important for the Sri Lankan government to promote conservation efforts for the remaining forests to better conserve biodiversity. The estimation suggests high carbon revenues, which can attract successful implementation of the projects through appropriate policy interventions and sectoral collaboration, which can then contribute to long-term economic development and climate change mitigation.</p></div>","PeriodicalId":100960,"journal":{"name":"Next Sustainability","volume":"3 ","pages":"Article 100035"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949823624000126/pdfft?md5=ffbd6eb27b3c8a7bb0b83b9f3cfec1a3&pid=1-s2.0-S2949823624000126-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140347066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
