Photo-catalysis (green energy) plays a significant role in energy conversion because of its potential to resolve environmental and energy problems. Due to its promising photo-catalytic, self-cleaning, antifungal, antimicrobial, and electronic properties, the semiconductor transition metal Titanium dioxide (TiO₂), after its discovery in 1972, has garnered significant attention in materials science. The first real-world application of splitting water into hydrogen and oxygen in the photo-electrochemical cell triggered the development of semiconductor photo-catalysis devices. Although its overall solar activity is minimal, it possesses the anticipated performance under UV light because of its extensive energy bandgap (3.0∼3.20) eV. TiO₂-based photocatalytic materials outperform others in terms of stability and photo-generation because they are inexpensive and non-toxic materials. In this review, we explore the influence of various dopants on the physicochemical and photocatalytic properties of TiO₂ –based nanomaterials. Particular emphasis is placed on incorporating metal and non-metal elements into the TiO₂ lattice through diverse synthesis techniques aimed at enhancing photocatalytic performance under visible light irradiation. Despite the promising outcomes, several challenges persist during the synthesis process, including structural inconsistencies and phase transformation. Through comprehensive characterization techniques, we investigate the enhanced functional performance of doped TiO₂ in environmental remediation, water purification, antibacterial applications, and energy conservation. The exceptional crystallinity and tunable properties of TiO₂-based nanocomposites make them promising candidates for next-generation photocatalytic applications. This review consolidates recent advancements and offers insights into innovative strategies aimed at enhancing the visible-light-driven photocatalytic efficiency of TiO₂-based systems.</div></div>","PeriodicalId":93548,"journal":{"name":"Energy nexus","volume":"19 ","pages":"Article 100495"},"PeriodicalIF":9.5,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144724687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the environmental significance of legacy waste, it is often overlooked in existing life cycle assessment (LCA) studies. This results in a critical gap in integrated LCA approaches that consider both waste streams within a single system boundary. This study addresses this gap by conducting an integrated attributional LCA, using the case study of Ghazipur landfill, Delhi, India. It covers processes from waste collection to energy recovery, using a functional unit of 1 tonne of MSW. LCA is performed using GaBi software and the Environmental Footprint 3. Four scenarios are analyzed: landfill without gas recovery (LF), landfill with gas recovery (LFGR) for fresh waste, and refuse-derived fuel (RDF) incineration, RDF gasification for legacy waste. LFGR shows an energy recovery of 73.04 kWh/tonne of MSW, significantly reducing the environmental impacts compared to LF. For legacy waste, RDF gasification outperforms incineration, showing an energy recovery of 306.1 kWh/tonne of MSW. The reduction cost of 1 tonne of CO₂ is 20 USD for LFGR and 32 USD for the RDF gasification. Sensitivity analysis highlights that the net electricity output predominantly affects the climate change category. This study highlights the potential of WtE for biomining and landfill reclamation, supporting circular economy transitions. The integrated LCA framework is replicable across developing nations with similar landfills, aligning with SDGs 7, 11, and 13.</div></div>","PeriodicalId":93548,"journal":{"name":"Energy nexus","volume":"19 ","pages":"Article 100472"},"PeriodicalIF":8.0,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144696658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The stoves were designed with optimized air hole configurations (14–18 holes, 10–20 mm diameter) and constructed using advanced materials, including fire clay bricks and fiber cement, to minimize heat loss and improve structural integrity. Experimental results demonstrated that the gasifier stoves achieved thermal efficiencies of up to 39 %, significantly outperforming the Super stove (32.7 %) and Zedtee stove (30.0 %). Heat loss for gasifier stoves using briquette charcoal was as low as 930 kJ, 4.3 times lower than that of the Super stove and 1.84 times lower than that of the Zedtee stove. Briquette charcoal provided the highest thermal efficiency, while eucalyptus chips achieved the highest combustion efficiency (98 %) despite their greater volatile matter content (59.36 %) and associated emissions. The gasifier stoves exhibited superior durability, with compressive strength (16.25 kN) exceeding that of conventional stoves (6.0 kN) by 2.7 times. These improvements reduced reliance on costly fuels, decreased biomass consumption, and mitigated emissions, achieving a CO/CO₂ ratio as low as 0.22 with LC fuel. Additionally, adopting the developed stove could reduce carbon dioxide emissions by approximately 380–760 kg CO₂ per household annually.

Three flat-sheet NF membranes of &lt; 200 µm structure parameter were tested as pressure stimuli-responsive (PSR) membranes in the FO process. The NF membranes are designed to reject divalent ions, such as sulfate, magnesium, and calcium, which are the main reason for scale formation and deposition in the MSF plant.

The water flux in the PSR NF membrane was insignificant at 0 bar pressure but increased several times when the feed pressure increased to 2 and 4 bar pressure. For the FO tests at 4 bar pressure, the average water flux in the PSR membranes was up to 2.6 times more than that in the CTA and TFC FO membranes, all without increasing the energy requirements of the FO process. In the tight NF membrane, the MSF brine dilution occurred by the permeation flow, but in the loose NF membrane, it was by permeation flow and ions' reverse diffusion from the draw solution to the feed solution.

Given the strong synergy between climate change drivers and major air contaminants, energy policy efforts that tackle both challenges simultaneously are becoming increasingly attractive to policymakers. Such integrated strategies not only advance long-term climate change mitigation goals but also improve air quality, thereby reducing adverse health effects that provide important incentives for their adoption. In this context, this study aims to assess the environmental co-benefits of implementing carbon taxation within a low-carbon pathway strategy, focusing on both the reductions in local air pollutants achieved through the low-carbon pathway itself and the additional reductions resulting from carbon taxation. Using a dynamic computable general equilibrium model (ECOGEM-Chile), the research assesses long-term emission trends and quantifies the potential co-benefits of reducing major air pollutants in Chile. The results indicate that adopting a low-carbon pathway leads to significant reductions in local air pollutants relative to the base year. Furthermore, the introduction of a carbon tax produces additional substantial reductions, reinforcing the positive environmental outcomes, and the important economic value of the resulting reduction in health effects.
