“…[1,2]. Molybdenum dioxide powders have been widely used in the fields of catalysis essentially in cracking and reforming of alkanes [3,4], sensors [5], recording materials [6], and electrode materials [7]. Generally, molybdenum dioxide is prepared by reducing molybdenum trioxide with hydrogen at high temperature and the product is coarse-grained or using alkali-metal borohydrides such as NaBH 4 [8].…”

MoO 2 nanoparticles with tremella-like morphology have been synthesized and characterized. Characterization by powder X-ray diffraction (XRD) and transmission electron micrographs (TEM) microscopy made possible to estimate that the nanosheets have ca. 12 nm and aggregate to form tremella-like structures. The resulting MoO 2 nanoparticles were used as catalyst for epoxidation of several olefins. The use of tert-butylhydroperoxide (tbhp), H 2 O 2 and cumenehydroperoxide (chp) as oxygen sources was screened under different reaction conditions, namely, solvent and temperature. The results from the catalytic experiments show that this catalyst was very efficient leading to very high conversion and product selectivity levels. In addition, the use of oxidant:olefin ratios close to 1 show that this catalyst is very efficient conducting olefin epoxidation. Further details are discussed in the work. The catalyst showed overall excellent performance with tbhp. When using H 2 O 2 , the catalyst showed good activity, which is very relevant as well. All these achievements contribute with a step forward in the development of more environmentally friendly processes.

“…A number of techniques was reported for the deposition of MoO 3 including pulse laser deposition [12], thermal evaporation [20], sputtering [21], sol-gel [1,22], spray pyrolysis [23], chemical vapour deposition [24,25], and electro-deposition [26]. The deposition of MoO 3 using evaporative techniques is advantageous as it can produce highly crystalline and stratified structures.…”
