Modified halloysite for heterogeneous conversion of saccharides to 5-hydroxymethylfurfural: recent advances and future trends

CLAY‑BASED PILLARED CATALYSTS FORSUSTAINABLEMETHYL OLEATE PRODUCTION

This research focuses on the catalytic dehydration of methyl 12-hydroxystearate, a derivative of non-edible castor oil, into methyl oleate using vanadia-pillared montmorillonite catalysts modified with zirconium, iron, and cerium. Structural and physicochemical analyses were conducted to establish correlations between...

Synthesis and Evaluation of a Novel Cassava-Based Starbon-Type Mesoporous Catalyst

Mesoporous materials are well suited as supports for heterogeneous catalysis because they facilitate the access and mobility of large molecules, thereby improving yields across a range of chemical reactions. Among these, mesoporous carbons can be advantageously synthesized from biobased sources and further functionaliz...

Which modification for which feedstock? a strategy-by-strategy review of Zr-MOF catalysts for biodiesel production

Catalyst design is central to producing sustainable biodiesel from waste feedstocks. Homogeneous bases such as NaOH and KOH are highly active but cause corrosion, saponification, and difficult separation, while conventional heterogeneous catalysts suffer from low surface area and poor tunability. Zirconium-based metal–...

Synthesis of Cobalt-Based Carbon Catalysts Derived from Triallyl Isocyanurate for the Highly Efficient Oxidation of 5-Hydroxymethylfurfural to 2, 5-Furandicarboxylic Acid

A Sustainable Phosphonoacetic Acid–Based Sulfonated Acidic Ionic Liquid Catalyst for Efficient Conversion of Alkaline and Dealkaline Lignin into Phenolics

The valorization of lignin into high-value phenolic compounds represents a pivotal step toward sustainable biorefineries, yet its recalcitrant structure poses significant challenges. Accordingly, we hypothesized that a hybrid inorganic and organic acid framework with controlled proton activity could provide tunable a...

Homogeneous catalytic oxidation of coconut shells to high-yield aromatic monomers and holocellulose in mild TMAH-imidazole.

An efficient homogeneous catalytic oxidation (HCO) process based on tetramethylammonium hydroxide derived deep eutectic solvent (TMAH-DES) was designed to enable "lignin-first" biorefining. Compared to the other TMAH-DES, the TMAH-imidazole exhibited superior HCO performance. An aromatic monomer yield of 19.5% (71% of...
