Angewandte Chemie International Edition, EarlyView.A well‐defined Ni/θ‐Al2O3 catalyst prepared by surface organometallic chemistry exhibits sharp temperature‐dependent behavior in dry reforming of methane. At 850°C, a dynamic induction process forms a transient carbide‐like NiCx phase that enables continuous carbon removal and coke resistance, whereas at 800°C incomplete carbon insertion leads to ...

This research aimed to enhance the accuracy of methane (CH₄) emissions estimates from natural wetlands by integrating satellite observations and advanced modeling techniques. Wetlands are among the largest natural sources of CH₄. However, current estimates carry large uncertainties due to the spatial and temporal variability of wetland characteristics.

Methane emission from the Western Siberia’s wetland ecosystems in 2000–2050
Acta Biologica SibiricaThe interannual variability of methane emissions from wetland ecosystems of Western Siberia in 2000–2050 has been investigated. Calculations of CH₄ emission were performed using the approach, in which the total daily methane flux is determined by the sum

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT In the hydrogen production routes from natural gas (methane), methane pyrolysis offers a cleaner option than the established steam methane reforming by producing CO2‐free hydrogen. However, in fixed bed reactors over solid catalysts, this technology experiences rapid catalyst deactivation due to carbon (coke) deposition encapsulating its ...
