Ruthenium‐Based Catalysts Supported on Lanthanum and Carbon‐Modified Alumina for Low‐Pressure Ammonia Synthesis

Carbon and Hydrogen, Volume 28, Issue 2, Page 255-268, June 2026.
We proposed a new “hydrogen transfer–desorption” synergistic regulation strategy and developed a Ru/Al2O3‐La‐C catalyst with dual functions. La‐O sites were constructed and carbon components were introduced into the catalyst to regulate the two key steps of hydrogen transfer and desorption on the catalyst surface, respectively, solving the problem of ...

Synergistic Enhancement of Photocatalytic Nitrate Reduction Over Fe‐Doped Bi/Bi2WO6 via Lewis Acidic Sites and Surface Plasmon Resonance

ChemCatChem, Volume 18, Issue 12, 26 June 2026.
The enhanced photocatalytic nitrate‐to‐ammonia conversion over H‐Fe‐B/BWO can be summarized as a cooperative process involving surface reaction chemistry and charge‐carrier dynamics. Fe dopants introduced into the Bi2WO6 lattice generate coordinatively unsaturated metal centers, which function as Lewis acidic sites capable of strongly interacting with ...

Evaluating the Intercropping Systems in the Context of Agroecological Resilience in the Current Era of the Changing Climate: A Scenario of Scientific Analysis of Last Decade Data

Climate Resilience and Sustainability, Volume 5, Issue 1, June 2026.
The extreme event of climate change (CC) has become more crucial, and under the current context of CC during the last decade. The cropping system (CS) approach is more appropriate than a suitable and established package of practices for individual crops, as CS interrelates with other components and resources related to sustainable farming under the ...
