摘要:The invention relates to synthesis of nanoparticles from hazelnut husk extract by green synthesis with high efficiency. Use of chemical is limited in the present invention and therefore the synthesis of nanoparticles is provided by green chemistry in the present invention. Said hazelnut may be Corylus and said hazelnut husk may be cob or shell of the hazelnut. In an embodiment of the invention said Corylus may be Colyrus colurna, Corylus americana Corylus avellana, Corylus avellana var. Avellana, Corylus avellana var. Pontica, Corylus chinensis, Corylus colchica, Corylus × colurnoides, Corylus cornuta, Corylus cornuta ssp. californica, Corylus cornuta ssp. cornuta, Corylus fargesii, Corylus ferox, Corylus ferox var. ferox, Corylus ferox var. thibetica, Corylus heterophylla, Corylus heterophylla var. heterophylla, Corylus heterophylla var. sutchuensis, Corylus jacquemontii, Corylus maxima, Corylus potaninii, Corylus sieboldiana, Corylus sieboldiana var. mandshurica, Corylus sieboldiana var. sieboldiana, Corylus wangii, Corylus wulingensis or Corylus yunnanensis.

摘要:High surface area, high entropy oxides comprising multiple metal cations in a single-phase fluorite lattice material enables intrinsic catalytic activity without platinum group metals, tunable oxygen storage capacity, and thermal stability. These properties can be obtained through a facile sol-gel synthesis to provide a low-temperature route for production of phase-pure multi-cationic oxides. The resulting materials achieved significantly higher surface area and catalytic performance, taking advantage of all the properties endowed by the various cations in the composition.
