    Methane emissions from oil and gas systems are underestimated in official inventories. Here the authors synthesize thousands of field measurements and develop an inventory-based model for a better understanding of why this underestimation exists and how it can be fixed.

    Partial oxidation of methane to value-added C1 products remains challenging due to the favorable formation of fully-oxidized CO2. Here, the authors show supported B2O3 catalysts with tri-coordinated BO3 units as the active site are highly selective in oxidizing methane to HCHO and CO.

    The two-dimensional morphology of molybdenum oxycarbide (2D-Mo2COx) nanosheets dispersed on silica is found vital for the dry reforming of methane. Here the authors show that the specific activity of 2D-Mo2COx/SiO2 exceeds that of other Mo2C-based catalysts by ca. 3 orders of magnitude.

    MoS2 nanoparticles catalyze the extraction of heteroatom S in hydrocarbons by adsorption onto S vacancies. Here, the authors show that S vacancy properties are highly site sensitive and that adsorption of thiophene leads to self-generation of a more open double vacancy site.

    Propylene production via propane dehydrogenation demands a highly stable catalyst that works without deactivation even at high temperatures. Here, the authors show that single-atom Pt included in thermally stable intermetallic PtGa works as an active and selective catalyst for propane dehydrogenation even at 600 °C for 96 h without deactivation.

    Reacting CO2 and ethane to achieve value-added C3 oxygenates offers opportunities to simultaneously reduce CO2 emissions and upgrade underutilized ethane in shale gas. Here, the authors report a successful oxygenate production strategy enabled by inserting CO2-derived CO into ethane-derived ethylene using a tandem reactor.

    Chinese government has implemented regulations to reduce mining-related methane emission since 2010. Here the authors estimated methane emissions in China using GOSAT satellite observation and results reveal a business-as-usual increase in methane emissions since 2010 despite those ambitious targets.

    The conversion of natural gas to chemicals and fuels via the Fischer-Tropsch synthesis process, depends on the ability of catalyst materials to suppress the formation of methane and carbon dioxide. Here, the authors develop a Co1Mn3-Na2S catalyst, which has a hydrocarbon product spectrum deviating from the Anderson–Schulz–Flory distribution.

    Understanding the growth pathway of faceted alloy nanoparticles at the atomic level is crucial to morphology control and property tuning, but remains a challenge. Here, the authors reveal the particle growth and facet formation mechanisms of octahedral Pt3Ni nanoparticles using multiple cutting-edge in situ techniques.

    A large proportion of methane emissions from natural gas production sites are released by a fraction of high-emitting sources. Here, using Monte Carlo simulations, the authors reveal that super-emitters occur due to abnormal process conditions, explaining component and site-based inventory discrepancies.
