A broad overview of the achievements and emerging areas in field Green Chemistry.
Biomass valorization for the production of various value-added biochemicals and biofuels plays a significant role in modern biorefineries/bioenergy towards climate neutrality future. Among developed techniques biorefining, hydrothermal biological treatments have been demonstrated to valorize raw biomass materials or upgrade biorefinery intermediate products afford respectably desired product yields. From perspective both green chemistry circular bioeconomy, whether inter-disciplinary...
Bio-oil is a mixture of organics produced from pyrolysis biomass. The in bio-oil serve as the feedstock for production hydrogen, chemicals, biofuels, and carbon materials. In many processes conversion bio-oil, heating required. thermal treatment induces polymerization/cracking producing coke. Coke could lower efficiency clog reactor chamber, deactivate catalyst, imposing main challenge utilization involving bio-oil. This review investigates coking issues upgrading including esterification,...
Abstract. Vanillin (VL), a phenolic aromatic carbonyl abundant in biomass burning emissions, forms triplet excited states (3VL∗) under simulated sunlight leading to aqueous secondary organic aerosol (aqSOA) formation. Nitrate and ammonium are among the main components of aerosols cloud or fog water. Under atmospherically relevant conditions, solutions composed either VL only with nitrate were subjected irradiation compare aqSOA formation via direct photosensitized oxidation absence presence...
The development of alternative routes for ammonia (NH3) synthesis with high Faradaic efficiency (FE) is crucial energy conservation and to achieve zero carbon emissions. Electrocatalytic nitrate (NO3−) reduction NH3 (e‐NO3RRA) a promising the energy‐intensive, fossil‐fuel‐driven Haber–Bosch process. implementation this innovative technique requires an efficient electrocatalyst in‐depth mechanistic understanding e‐NO3RRA. In study, we developed ultrathin sheet (µm) iron–nickel nanoflower...
Electrocatalytic hydrogenation (ECH) is an option for stabilizing or upgrading bio-oil that employs mild conditions (≤80 °C and ambient pressure) compared to hydrotreatment. In this study, phenol, guaiacol (2-methoxyphenol), syringol (2,6-dimethoxyphenol) were chosen as model lignin-like substrates because of their abundance in high resistance relative the carbonyl compounds. Cathodic reduction was catalyzed by ruthenium supported on activated carbon cloth (Ru/ACC), a novel electrocatalyst....

The electrochemical selective oxidative transformation of lignin feedstocks into valuable oxygenated aromatics is essential to establish a sustainable biorefinery.
<p>Anthropogenic climate and environmental changes increasingly threaten the sustainability of life on Earth, hindering sustainable development human societies. These detrimental ecological are driven by activities that have elevated atmospheric levels greenhouse gases toxic substances, increased inorganic organic pollutants in water bodies, led to accumulation solid waste soils. Over next two three decades, impacts change, pollution, soil contamination expected intensify, posing...
Direct converting low concentration CO2 in industrial exhaust gases to high-value multi-carbon products via renewable-energy-powered electrochemical catalysis provides a sustainable strategy for utilization with minimized separation and purification capital energy cost. Nonetheless, the electrocatalytic conversion of dilute into value-added chemicals (C2+ products, e.g., ethylene) is frequently impeded by rate weak carbon intermediates' surface adsorption strength. Here, we fabricate range...
