Dry ice-mediated rational synthesis of edge-carboxylated crumpled graphene nanosheets for selective and prompt hydrolysis of cellulose and eucalyptus lignocellulose under ambient reaction conditions
( Royal Society of Chemistry , 2020 , Article)Edge-selectively carboxylated graphene (ECG) crumpled nanosheets are of great importance in potential applications; however, their catalytic activity towards biomass hydrolysis is not yet highlighted. Herein, we rationally ... -
Highly dispersed Pt nanoparticles on ultrasmall EMT zeolite: A peroxidase-mimic nanoenzyme for detection of H2O2 or glucose
( Elsevier Inc. , 2020 , Article)In past decade, Pt-based nanomaterials as peroxidase mimics have attracted much attention for H2O2 and glucose detection. However, easy aggregation of Pt nanoparticles (Pt NPs) greatly decreases their peroxidase-like ... -
Hollow Mesoporous Carbon Nanospheres Loaded with Pt Nanoparticles for Colorimetric Detection of Ascorbic Acid and Glucose
( American Chemical Society , 2020 , Article)With the rapid development of nanotechnology and catalysis science, numerous enzyme-mimicking nanomaterials have been rationally designed as the substitutes for natural enzymes. Herein, the Pt-loaded hollow mesoporous ... -
Lanthanide oxide modified H-Mordenites: Deactivation of external acid sites in the isopropylation of naphthalene
( Elsevier B.V. , 2016 , Article)The external surface of the H-Mordenite (MOR) was modified with lanthanide oxides such as CeO2, La2O3, Pr2O3, Sm2O3, Dy2O3, and Yb2O3, to investigate the deactivation of external acid sites. It is confirmed that the ... -
Nonenzymatic nitrogen-doped carbon nanofber-supported NiOx glucose sensor
( M Y U Scientific Publishing Division , 2017 , Article)The glucose electrooxidation reaction at NiOx nanoparticles loaded on a nitrogen-doped carbon nanofber (N-CNF)-modifed glassy carbon electrode (NiOx@N-CNF/GCE) in an alkaline medium was studied. The N-CNF was produced by ... -
Ordered, highly zeolitized mesoporous aluminosilicates produced by a gradient acidic assembly growth strategy in a mixed template system
( American Chemical Society , 2016 , Article)Tremendous efforts have been made in recent years to synthesize ordered mesoporous zeolite materials, because of the accelerating demands of industrial bulky molecule conversion. Here, we develop a novel gradient acidic ... -
Synthesis of Podlike Magnetic Mesoporous Silica Nanochains for Use as Enzyme Support and Nanostirrer in Biocatalysis
( American Chemical Society , 2020 , Article)Magnetic mesoporous materials have attracted great interest due to their combined property of magnetic nanomaterials and mesoporous materials as well as their potential applications in catalysis, bioenrichment, drug delivery, ...
