Hydrogen production from thermochemical conversion has been considered the most promising technology for use of biomass, and some novel methods are also being developed low cost high efficiency.
Abstract The emerging solar desalination by interfacial evaporation shows great potential for alleviating the global freshwater crisis. However, salt deposition on whole surface during steam generation leads to a deterioration in rate and long‐term stability. Herein, it is demonstrated that hydrogel‐based 3D structure can serve as an efficient stable evaporator localized crystallization high‐salinity brine desalination. Under function of micron‐grade transport management edge‐preferential...
Interfacial solar-driven evaporation is an effective and sustainable approach to convert solar energy heat for desalination. However, maintaining a rapid rate long-term stability critical challenge that needs be addressed urgently facilitate practical applications of this technology. Here, taking advantage the inherent porosity, wettability, low thermal conductivity wood, we develop flexible mildew-resistant aerogel derived from natural wood as substrate evaporators stable efficient The...
Biomass-derived photothermal conversion materials are considered to be promising evaporator choices for cost-effective, sustainable, and environmentally friendly solar vapor generation. Herein we demonstrate a double-layer flamed straw, which is typical solar-driven interfacial that can directly convert energy into heat then localize at interface Benefiting from the unique structure of natural corn straw exhibits high absorbance 91%, ultralow thermal conductivity (0.042 W m–1 K–1),...
Gas hydrates have an important role in environmental and astrochemistry, as well energy materials research. Although it is widely accepted that gas accumulation necessary process during hydrate nucleation, how guest molecules aggregate remains largely unknown. Here, we performed molecular dynamics simulations to clarify the nucleation path of methane hydrate. We demonstrated gather with a three-body pattern corresponding free minimum three-methane hydrophobic interaction. Methane fluctuate...
Abstract High-concentration organic wastewater has become a great challenge for treatment due to its toxicity and non-biodegradability. Traditional water methods focus on removing or destroying pollutants rather than considering the high-concentration as resource. As an ambitious sustainability goal, resource recovery from achieve zero liquid discharge (ZLD) attracted widespread attention. Here, hydrate-based method is proposed treat textile facilitate reuse of dyes enhance reclamation. The...
Gas hydrates pose a serious flow assurance challenge due to their ability form, agglomerate, and block subsea flowlines on relatively fast time scales, leading the loss of production potential safety environmental risks. The hydrate management strategy based antiagglomerant inhibitors has gained significant interest in recent years, particularly long tiebacks, maturing fields, deep-water projects. However, most antiagglomerants used are not environmentally friendly, compatibility issues with...
Carbon storage in the form of solid hydrate under seafloor has been considered to be promising for greenhouse gas control. Yet, open issues still remain on role organic matters abundant marine environments kinetics formation; particular interest is involvement acid-dissolvable accompanying acidification upon CO2 injection. In this work, formation presence was in-situ monitored through low-field nuclear magnetic resonance technique. It found that could kinetically promote hydrate; effect...
Gas hydrates have attracted substantial attention in energy and environmental research as a medium for storage transport, gas separation, carbon dioxide sequestration. However, the fundamental kinetics of hydrate formation remain poorly understood. Here, we report on new approach determining reaction rate constant formation. High-resolution X-ray computed tomography measurements were performed to monitor xenon water droplet, shell growth model was developed quantify The determined by...
Theoretically, impurities can be excluded from hydrate structure and pure water extracted during formation. We achieved the heavy metal (Cu2+ in this study) removal aqueous solution by process. The samples were analyzed X-ray computed tomography (CT). Boundary layer analysis was conducted to reveal mechanism of ion exclusion. Moreover, effect initial concentrations on characteristics solid–liquid separations optimized. main findings as follows: (1) Solution pockets trapped identified...
A deeper understanding of the kinetics CO2 hydrate formation in complicated natural environment is required for its enhanced sequestration. Here we found that organics-coated nanoclays enriched sediments could contribute to a 92% decline induction time formation. This can be ascribed negative charges carried by organics and resulting ordered arrangement surrounding water molecules. It was, first time, proposed abundant functional groups from coating function as protecting crust enabling...
