Infrared spectrometric studies of the surface basicity of metal oxides and zeolites using adsorbed probe molecules
TL;DR: In this paper, it is concluded that no probe can be universally used and that both acid probes can lead on highly basic metal oxides to polydentate (bulk) species which do not result from their adsorption but from their reaction with the given oxide.

Soybean oil transesterification over zinc oxide modified with alkali earth metals
Zhenqiang Yang,Wenlei Xie +1 more
TL;DR: In this article, the preliminary results of using alkaline earth metal-doped zinc oxide as a heterogeneous catalyst for transesterification of soybean oil were reported, where the highest catalytic activity was obtained with ZnO loaded with 2.5mmol Sr(NO 3 ) 2 /g, followed by calcination at 873k for 5h.

Calcium-based mixed oxide catalysts for methanolysis of Jatropha curcas oil to biodiesel.
TL;DR: In this paper, CaMgO and CaZnO were used for the transesterification of Jatropha curcas oil (JCO) with methanol, in order to evaluate their potential as heterogeneous catalysts for biodiesel production.

Nawin Viriya-empikul,Pawnprapa Krasae,Waraporn Nualpaeng,Boonyawan Yoosuk,Kajornsak Faungnawakij +4 more
TL;DR: The solid oxide catalysts derived from the industrial waste shells of egg, golden apple snail, and meretrix venus were used as biodiesel production catalysts as discussed by the authors, and their catalytic activity in transesterification of palm olein oils and their physicochemical properties (by TG/DTA, EDX, SEM, N 2 sorption, CO 2 -TPD, and XRD) were systematically investigated.

Stabilized magnesia: A novel catalyst (support) material
TL;DR: Magnesium aluminium hydroxycarbonate compounds with the hydrotalcite structure (Feitknecht compounds) and molar ratios of Mg-to-Al of 5-10 have been prepared without the formation of considerable amounts of separate magnesium compounds as discussed by the authors.
