Polyoxometalate Catalysis of the Aerobic Oxidation of Hydrogen Sulfide to Sulfur

Influence of peroxometallic intermediaries present on polyoxometalates nanoparticles surface on the adipic acid synthesis

“…Due to their solubility in the reaction medium, heteropolyacids were supported onto an activated carbon fiber A20 (PMo/A20) whose preparation procedure is described in previous work [14]. [15,16,17].…”

Eco-Friendly Synthesis of Bioactive Heterocycles

“…The application of Preyssler catalyst is mostly limited and only a few demonstrations of catalytic activity have been reported [23]. The structure of this catalyst is shown in Fig.…”

“…Recently, HPAs which are low in toxicity and they being recyclable have attracted special attention [27][28][29] 14 − with high thermal and hydrolytic stability throughout a wide pH range has been largely overlooked and only a few reports for catalytic performance of this catalyst have been cited [38]. This HPA is remarkable because of the following advantages: (1) strong Brønsted acidity with 14 titrable acidic protons, (2) high thermal stability, (3) high hydrolytic stability (pH 0-12), (4) reusability, (5) more safety, (6) lower waste quantity, (7) better separability, (8) less corrosiveness, (9) high oxidation potential, and (10) greenness [39][40][41][42].…”

An Innovative Approach to Oxidative Removal of Hydrogen Sulfide Using the Solution of Peroxo Heteropolyacid

“…For example, the system of HPA/H 2 O 2 has been widely employed in the field of deep-desulfurization of fuel oil (Te et al, 2001;Ying et al, 2009;Wang et al, 2010). However, there are only quite limited reports on H 2 S removal using HPA (Kuznetsova and Yurchenko, 1989;Harrup and Hill, 1994;Wang, 2003;Song et al, 2011;Ma et al, 2012;Zou et al, 2013;Kim et al, 2014). Furthermore, the study on H 2 S removal using PHPA has never been reported to date.…”
