Catalytic Pyrolysis of Torrefied Municipal Solid Waste Using Local Iron for Improved Bio‐Oil Yield and Energy Efficiency

open access: yesEnergy Science &Engineering, EarlyView.
Catalytic Pyrolysis of Torrefied Municipal Solid Waste to sustainable bio‐oil. ABSTRACT South Africa faces growing municipal solid waste (MSW) accumulation and energy insecurity due to fossil fuel dependence. Torrefaction improves MSW for waste‐to‐energy use, while conventional pyrolysis produces low‐quality oxygen‐rich bio‐oil.

Hydrogen Production With Water Electrolysis Technologies: Advances, Performance, and Potential Use for Low‐Gradient Combustion

open access: yesEnergy Science &Engineering, EarlyView.
This review links recent advances in water electrolysis with hydrogen utilization in low‐gradient combustion systems. While hydrogen eliminates direct CO2 emissions, its environmental and economic benefits depend strongly on production pathways, system‐level efficiency, and NOx mitigation through MILD/FLOX/HiTAC combustion.

Engineering Cobalt‐Based Thin Films for Fischer–Tropsch Synthesis

open access: yesSmall, EarlyView.
Cobalt thin films with tailored crystalline phases and oxidation states serve as well‐defined model Fischer–Tropsch catalysts. In situ synchrotron GIXRD reveals distinct reduction behaviour and phase evolution, while catalytic testing demonstrates phase‐dependent hydrocarbon selectivity and improved structural stability. These model thin‐film catalysts

Rhodium Cluster Catalysts Enable Efficient Catalytic Hydroformylation in Mild Conditions: Cluster Size Dependence

open access: yesSmall, EarlyView.
Nanometer‐sized Rh clusters provide a specific reaction environment that facilitates the balanced co‐adsorption of styrene, CO, and H, thereby promoting hydroformylation. ABSTRACT The size of the reactive metal domain, termed an ‘ensemble’, in supported metal catalysts critically influences their catalytic activity.

Unbiased Tandem System for Simultaneous Methane and Glycerol Upgrading to Formic Acid Under Ambient Conditions

open access: yesSmall, EarlyView.
A bias‐free photovoltaic‐photoelectrochemical tandem system enables simultaneous methane and glycerol upgrading to formic acid under ambient conditions. The cathode generates hydrogen peroxide for methane oxidation, while the photoanode efficiently oxidizes glycerol.

Downsize Effect on Photocatalytic Syngas Production of a 2D Metal Organic Framework—Tuning the Selectivity From HER to CO2RR via Dimensional Modulation and Mechanical Exfoliation of 2D Metal‐Organic Layers

open access: yesSmall Methods, EarlyView.
A cobalt(II) 2D MOF (2D) has been downsized by covalent bond breaking to form a 1D MOF (1D) and by sonication, to form a 2D exfoliated MOF (2D‐ex). Photocatalytic CO2 reduction shows that 2D and 1D lead to H2‐enriched syngas, whereas 2D‐ex leads to CO‐enriched syngas.
