Themed collection SDG13: Climate Action- chemistry of greenhouse gases, 2022

This review summarizes in detail the current knowledge in the chemical compositions, formation mechanisms, and physicochemical properties of secondary organic aerosols formed from monocyclic aromatic hydrocarbons.

Particulate nitrate photolysis can lead to the formation of secondary inorganic and organic aerosols that affect climate, air quality, and human health.

An overview of the strategies for boosting C₂₊ selectivity by manipulating CO*(CO).

CO₂ sequestration in shales is controlled by the intrinsic properties of shale and external factors shown in grey and green boxes, respectively. The adsorption capacity (orange box) is influenced by both intrinsic properties and external factors.

Iron in mineral dust can catalyze reactions with atmospheric organics that lead to the formation of brown carbon (BrC) that impact the climate in a number of ways.

This review article describes the main technologies for CO₂ capture, highlights the latest research status of nanomaterials for CO₂ capture, and investigates the influence of surface microstructure and modification of materials on CO₂ capture.

We studied the mechanisms of cooking oil decomposition that lead to emission of aldehydes, an important group of air pollutants, from food cooking.

CF₄ hydrolytic decomposition was studied at three-coordinated Al sites on the γ-Al₂O₃ (110) surface.

The decomposition rates of organic hydroperoxides derived from ozonolysis of terpene-alcohol in the presence of short-chain alcohols in aqueous organic media is markedly increased as the temperature is increased.

Sn@NPC composite is synthesized by a design involving the upcycling of Sn electroplating sludge, and exhibits high selectivity and stability for CO₂RR to HCOOH.

Polycatechol and polyguaiacol are light-absorbing and water-insoluble compounds that are produced from biomass burning emissions. The aerosol can act as seeds for cloud droplet formation.

Nitrite reduction by Fe(II) in an agricultural sediment and complete conversion to N₂O suggests chemodenitrification is important to N₂O emissions.

We applied the 1D model SOSAA to simulate the atmospheric concentrations of OH, NO₃, and H₂SO₄ from 2007 to 2018 at SMEAR II. The results showed that daily OH increased by 2.39% per year and NO₃ and H₂SO₄ decreased by 3.41% per year and 2.78% per year, respectively.

New emissions of methane and chloroform, with concurrent depositions of ozone and hydrogen were determined from the peat bogs of Ireland.

Three essential factors, including the final injection pressure, total organic carbon (TOC), and porosity of open pores, could determine methane storage and long-term CO₂ sequestration potentials in depleted shale reservoirs.

An innovative plasma-induced strategy was employed to one-step prepare defect-enriched porous LaMnO₃ and cerium-substituted LaMnO₃ perovskite oxides with excellent performance in methane combustion.

This work quantifies the core–shell structure of nano-confined CO₂ molecules under pressure in silica pores using in operando small-angle neutron scattering (SANS) measurements and molecular dynamics simulations.

The unusual enhancement effect of HF-treated sludge carbon for CO₂ adsorption was found, which contributed to the HF activation role, resulting in the formation of abundant CO₂-philic ultra-micropores and C–F functional groups.

Degradation mechanisms of simple aliphatic amines during ozonation have been investigated by using the DFT method.

Chamber experiments may over emphasize peroxy radical cross reactions due to lower concentrations of reactants that directly convert OH into HO₂.

Divergent soil biogeochemical conditions will determine the fate and pathways of labile carbon released during permafrost thaw, thereby influencing the production of greenhouse gas mixtures and radiative forcing of tundra soils.

Sunlight photolysis of cysteine and dissolved organic matter (DOM) from freshwater to open ocean water sources generates carbonyl sulfide (COS) but not carbon disulfide (CS₂).

With an ongoing interest in displacing petroleum-based sources of energy with biofuels, we measure and model the formation and composition of secondary organic aerosol (SOA) from organic compounds present in biofuels.

Isotope tracer experiments reveal that rates of dissolved organic matter partial photochemical oxidation are considerably underestimated in arctic surface waters.
