This review comprehensively summarizes the synthetic strategies, gas sensing applications, and pollutant removal performance of inorganic quantum dots (IQDs). It highlights the recent advancements in organic-phase and aqueous-phase synthesis methods that enable precise control over IQDs size, surface chemistry, and optoelectronic properties for environmental applications. The discussion emphasizes the exceptional gas sensing performance of IQDs through surface charge modulation, fluorescence quenching mechanisms, and quantum confinement effects, thus enabling ultrasensitive detection of nitrogenous and sulfur-containing pollutants. For environment remediation, IQDs demonstrate superior photocatalytic efficiency via tailored bandgap engineering, heterojunction design, and enhanced charge separation for gaseous pollutant degradation. Further, the critical challenges of IQDs in the environmental applications have been proposed from the aspects of scalable synthesis, long-term stability under operational conditions, and toxicity assessments. Overall, this review outlines the sustainable development pathways involving eco-friendly IQDs alternatives and circular economy approaches, which provide deep insights for designing next-generation IQDs systems for environmental applications.

Direct air capture (DAC) of CO2 is attracting more and more attention due to its indispensable role in achieving net-zero carbon emissions by 2050 globally. The large-scale development and deployment of DAC rely heavily on renewable energy to ensure its sustainability and economic feasibility. The feasibility of coupling DAC with renewable energy will ultimately determine its potential as a viable negative emission technology for climate change mitigation. This review examines three representative DAC technology pathways and provides a comprehensive perspective on their integration with renewable energy sources. While current research primarily focuses on the necessity and conceptual feasibility of DAC-renewable integration, limited studies explore specific operational strategies to effectively manage fluctuations and intermittency in the renewable energy supply. Thus, this review aims to bridge the gap between DAC as an energy-intensive process and renewable energy sources, highlighting key challenges and future research directions for optimizing DAC systems in renewable energy-driven frameworks.
