Pore Size Effects of Mesoporous N‐Doped Carbon Nanospheres as Advanced Support Material on the Activity of Molybdenum Sulfide Catalysts for the Hydrogen Evolution Reaction

Advanced Functional Materials, Volume 36, Issue 35, 30 April 2026.
By tuning the pore size of mesoporous N‐doped carbon (MPNC) nanospheres as support material for molybdenum sulfide, the electrochemical activity of the composite material for the hydrogen evolution reaction can be optimized. An ideal MPNC pore size of 60 nm allows a high number of molybdenum sulfide active sites while maintaining efficient proton and ...

Evaluation of the Bioenergetic Potential of Marine Macroalgae in Anaerobic Digestion Systems

CLEAN – Soil, Air, Water, Volume 54, Issue 4, April 2026.
ABSTRACT This study evaluated the production of biogas by anaerobic digestion, using three groups of marine macroalgae: Chlorophytes (green), Phaeophytes (brown), Rhodophytes (red), and their mixture (GRB). The objective was to investigate how the composition of each group influences the production of biogas and methane, as well as the use of digestate
