BiVO4@MoS2 core-shell heterojunction with improved photocatalytic activity for discoloration of Rhodamine B

Heterostructural transformation of mesoporous silica–titania hybrids

“…Hybrids of metal oxides have been prepared by the multi-step preparation to hybridize hetero-components with presynthesized metal oxide nanostructures (building block approach) in addition to the sol-gel reaction to achieve more homogeneously elemental distribution through the materials (bottom-up approach) 4,5 . Macro-to nanoscopic separation of each components in solids 6,7 , elemental doping [8][9][10][11] , and core-shell structures [12][13][14][15] are typical hierarchical structures of hybrids of metal oxides, where various amorphous and crystalline domains are involved as a component.…”

Self-healing microcapsules encapsulated with carbon nanotubes for improved thermal and electrical properties

“…Zhong et al, 19 have reported a method to anchor atomically dispersed platinum atoms on carbon nano-tubes (Pt-CNT) in an ultra-low temperature solution, to reduce the free energy of Pt atoms in the solution and thus reduce their agglomeration. Xu et al, 20 have fabricated bismuth vanadate (BiVO 4 ) nano-rods by electrospinning and successfully synthesized a core-shell heterojunction by growing molybdenum disulde nano-sheets (MoS 2 ) on (BiVO 4 ) nano-rods by solvo-thermal technique. Wang et al, 21 have reported improved catalytic activity for oxygen evolution reaction of ruthenium catalyst by in situ method.…”
