Clay-supported zinc oxide as catalyst in pyrolysis and deoxygenation of licuri (Syagrus coronata) oil

In situ self-exsolved ultrasmall Fe2P quantum dots from attapulgite nanofibers as superior cocatalysts for solar hydrogen evolution

“…Among them, attapulgite (ATP), a magnesium aluminum silicate clay featuring an unusual fiber-like morphology with a high aspect ratio and large surface area, 36 has been used as an ideal host matrix for accommodating catalysts with high dispersion and uniform distribution for catalytic applications ranging from electrocatalysis 37 to photocatalysis 38–40 and thermal catalysis. 33,34 Apart from its structural merits as a support, it is worth mentioning that ATP is naturally doped with Fe ions (Fe 2+/3+ ) in the form of the –O–Fe–O– structure, which is isostructural to the –O–Mg–O–/–O–Al–O– structure. 41,42 As many Fe-based compounds, such as Fe 2 P, 21,43 Fe 3 C, 44,45 and FeSe, 46 have been identified as excellent catalysts for electrocatalytic and photocatalytic HERs, we therefore envision that if the doped Fe ions in ATP can be exsolved and simultaneously converted into targeted Fe active components on the surface of ATP, 47,48 an advanced supported catalyst that combines the merits of the ATP substrate and the exsolved Fe components would be achieved with collaboratively optimized functionality and catalyst-support interfacial interaction.…”

“…Natural clay minerals consist of Earth-abundant elements with different types of nanostructures that have been employed in preparing many catalytic materials, [31][32][33][34][35] whereas they typically serve as catalyst supports due to their large specific surface area, good chemical stability, and excellent mechanical strength. Among them, attapulgite (ATP), a magnesium aluminum silicate clay featuring an unusual fiber-like morphology with a high aspect ratio and large surface area, 36 has been used as an ideal host matrix for accommodating catalysts with high dispersion and uniform distribution for catalytic applications ranging from electrocatalysis 37 to photocatalysis [38][39][40] and thermal catalysis.…”

Emerging Lipids from Arecaceae Palm Fruits in Brazil

“…Biodiesel production is also among the industrial applications suggested for BRP oil [19,213]. Many authors reported LIK oil as a raw material for biofuel production [18,68,153,154,214]. Araújo et al [154] indicated that LIK oil has excellent properties for jet fuel, as 90% of its composition fits well with the requirements for this product.…”

“…The addition of LIK oil to biofilms based on arrowroot starch caused significant and positive effects on its mechanical, solubility, and color properties, indicating that it may be an alternative and sustainable raw material for the development of biofilms used in biodegradable packaging [222]. Oliveira et al [214] studied the properties and applicability of vermiculite clay as an alternative catalyst and catalytic support for zinc oxide in the pyrolysis of LIK oil, suggesting the formation of a bio-oil rich in hydrocarbons.…”
