Optimized Nb-Based Zeolites as Catalysts for the Synthesis of Succinic Acid and FDCA.
El Fergani M, Candu N, Tudorache M, Granger P, Parvulescu VI, Coman SM. El Fergani M, et al. Molecules. 2020 Oct 22;25(21):4885. doi: 10.3390/molecules25214885. Molecules. 2020. PMID: 33105761 Free PMC article.
The catalytic behavior of these catalysts, in terms of conversion and especially the selectivity, mainly depended on the base/acid sites ratio. Thus, the HMF/glucose wet oxidation occurred with a total conversion and a selectivity to SA of 37.7% (from HMF) or 69.1% (from g …

Metal-Incorporated Mesoporous Silicates: Tunable Catalytic Properties and Applications.
Ramanathan A, Subramaniam B. Ramanathan A, et al. Molecules. 2018 Jan 29;23(2):263. doi: 10.3390/molecules23020263. Molecules. 2018. PMID: 29382121 Free PMC article. Review.
The metal-incorporation is carried out using one-pot synthesis procedures that are amenable to easy scale-up. By such tuning, M-KIT-6 catalysts are shown to provide remarkable activity and selectivity in industrially-significant reactions, such as alcohol dehydration, ethy …

One-pot synthesis of acid-base bifunctional catalysts for biodiesel production.
Dai YM, Li YY, Jia-Hao-Lin, Chen BY, Chen CC. Dai YM, et al. J Environ Manage. 2021 Dec 1;299:113592. doi: 10.1016/j.jenvman.2021.113592. Epub 2021 Aug 31. J Environ Manage. 2021. PMID: 34479149
We investigated the use of niobium and three alkali metal oxides (Li, Na, and K) as M(y)NbO(X) (M = Li, Na, K) composite as acid-base catalysts for biodiesel production. M(y)NbO(X) catalysts were prepared using a simple solid-state reaction, mixing, and grind …
