Effect of lanthanum addition on the properties of potassium-free catalysts for ethylbenzene dehydrogenation
(2008)
The ethylbenzene dehydrogenation in the presence of steam is the dominant technology for styrene production, one of the most important high value chemicals. The most widely used industrial catalyst comprises potassium-promoted ...
Facile synthesis of potassium poly(heptazine imide) (PHIK)/Ti-based metal–organic framework (MIL-125-NH 2 ) composites for photocatalytic applications
(American Chemical Society, 2017-07)
Photocatalytically active composites comprising potassium poly(heptazine imide) (PHIK) and a Ti-based metal-organic framework (MOF, MIL-125-NH2) are prepared in situ by simply dispersing both materials in water. The driving ...
Use of levoglucosan, potassium, and water-soluble organic carbon to characterize the origins of biomass-burning aerosols
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
Three chemical species related to biomass burning, levoglucosan, potassium and water-soluble organic carbon (WSOC), were measured in aerosol samples collected in a rural area on the outskirts of the municipality of Ourinhos ...
